Depending upon how the DIMM Modules are populated in each memory channel, a number of different configurations can exist. Single-Channel Mode In this mode, all memory cycles are directed to a single-channel. Single-channel mode is used when either Channel A or Channel B DIMM connectors are populated in any order, but not both. Dual-Channel Mode - Intel(R) Flex Memory Technology Mode The IMC supports Intel Flex Memory Technology Mode. Memory is divided into symmetric and asymmetric zones. The symmetric zone starts at the lowest address in each channel and is contiguous until the asymmetric zone begins or until the top address of the channel with the smaller capacity is reached. In this mode, the system runs with one zone of dual-channel mode and one zone of single-channel mode, simultaneously, across the whole memory array. Note: Channels A and B can be mapped for physical channel 0 and 1 respectively or vice versa; however, channel A size must be greater or equal to channel B size. Figure 2. Intel(R) Flex Memory Technology Operations TOM C Non interleaved access B C B B CH A CH B Dual channel interleaved access B CH A and CH B can be configured to be physical channels 0 or 1 B - The largest physical memory amount of the smaller size memory module C - The remaining physical memory amount of the larger size memory module Dual-Channel Symmetric Mode Dual-Channel Symmetric mode, also known as interleaved mode, provides maximum performance on real world applications. Addresses are ping-ponged between the channels after each cache line (64-byte boundary). If there are two requests, and the second request is to an address on the opposite channel from the first, that request can be sent before data from the first request has returned. If two consecutive cache lines are requested, both may be retrieved simultaneously, since they are ensured to Desktop 4th Generation Intel(R) CoreTM Processor Family, Desktop Intel(R) Pentium(R) Processor Family, and Desktop Intel(R) Celeron(R) Processor Family March 2015 Datasheet - Volume 1 of 2 Order No.: 328897-010 21 Processor--Interfaces be on opposite channels. Use Dual-Channel Symmetric mode when both Channel A and Channel B DIMM connectors are populated in any order, with the total amount of memory in each channel being the same. When both channels are populated with the same memory capacity and the boundary between the dual channel zone and the single channel zone is the top of memory, the IMC operates completely in Dual-Channel Symmetric mode. Note: The DRAM device technology and width may vary from one channel to the other. 2.1.3.1 System Memory Frequency In all modes, the frequency of system memory is the lowest frequency of all memory modules placed in the system, as determined through the SPD registers on the memory modules. The system memory controller supports one or two DIMM connectors per channel. The usage of DIMM modules with different latencies is allowed, but in that case, the worst latency (among two channels) will be used. For dual-channel modes, both channels must have a DIMM connector populated and for single-channel mode only a single channel may have one or both DIMM connectors populated. Note: In a two-DIMM Per Channel (2DPC) layout memory configuration, the furthest DIMM from the processor of any given channel must always be populated first. 2.1.3.2 Intel(R) Fast Memory Access (Intel(R) FMA) Technology Enhancements The following sections describe the Just-in-Time Scheduling, Command Overlap, and Out-of-Order Scheduling Intel FMA technology enhancements. Just-in-Time Command Scheduling The memory controller has an advanced command scheduler where all pending requests are examined simultaneously to determine the most efficient request to be issued next. The most efficient request is picked from all pending requests and issued to system memory Just-in-Time to make optimal use of Command Overlapping. Thus, instead of having all memory access requests go individually through an arbitration mechanism forcing requests to be executed one at a time, the requests can be started without interfering with the current request allowing for concurrent issuing of requests. This allows for optimized bandwidth and reduced latency while maintaining appropriate command spacing to meet system memory protocol. Command Overlap Command Overlap allows the insertion of the DRAM commands between the Activate, Pre-charge, and Read/Write commands normally used, as long as the inserted commands do not affect the currently executing command. Multiple commands can be issued in an overlapping manner, increasing the efficiency of system memory protocol. Out-of-Order Scheduling While leveraging the Just-in-Time Scheduling and Command Overlap enhancements, the IMC continuously monitors pending requests to system memory for the best use of bandwidth and reduction of latency. If there are multiple requests to the same open page, these requests would be launched in a back-to-back manner to make optimum use of the open memory page. This ability to reorder requests on the fly allows the IMC to further reduce latency and increase bandwidth efficiency. Desktop 4th Generation Intel(R) CoreTM Processor Family, Desktop Intel(R) Pentium(R) Processor Family, and Desktop Intel(R) Celeron(R) Processor Family Datasheet - Volume 1 of 2 March 2015 22 Order No.: 328897-010 Interfaces--Processor 2.1.3.3 Data Scrambling The system memory controller incorporates a Data Scrambling feature to minimize the impact of excessive di/dt on the platform system memory VRs due to successive 1s and 0s on the data bus. Past experience has demonstrated that traffic on the data bus is not random and can have energy concentrated at specific spectral harmonics creating high di/dt, which is generally limited by data patterns that excite resonance between the package inductance and on die capacitances. As a result, the system memory controller uses a data scrambling feature to create pseudo-random patterns on the system memory data bus to reduce the impact of any excessive di/dt. 2.2 PCI Express* Interface This section describes the PCI Express* interface capabilities of the processor. See the PCI Express Base* Specification 3.0 for details on PCI Express*. 2.2.1 PCI Express* Support The PCI Express* lanes (PEG[15:0] TX and RX) are fully-compliant to the PCI Express Base Specification, Revision 3.0. The processor with the PCH support the configurations shown in the following table (may vary depending on PCH SKUs). Table 7.

The PCI Express* configuration uses standard mechanisms as defined in the PCI Plugand-Play specification. The processor PCI Express* ports support Gen 3. At 8 GT/s, Gen 3 operation results in twice as much bandwidth per lane as compared to Gen 2 operation. The 16 lanes PEG can operate at 2.5 GT/s, 5 GT/s, or 8 GT/s. Gen 3 PCI Express* uses a 128b/130b encoding that is about 23% more efficient than the 8b/10b encoding used in Gen 1 and Gen 2. The PCI Express* architecture is specified in three layers - Transaction Layer, Data Link Layer, and Physical Layer. See the PCI Express Base Specification 3.0 for details of PCI Express* architecture. 2.2.3 PCI Express* Configuration Mechanism The PCI Express* (external graphics) link is mapped through a PCI-to-PCI bridge structure.

PCI Express* Related Register Structures in the Processor PCI Express* Device PEG0 PCI-PCI Bridge representing root PCI Express ports (Device 1 and Device 6) PCI Compatible Host Bridge Device (Device 0) DMI PCI Express* extends the configuration space to 4096 bytes per-device/function, as compared to 256 bytes allowed by the conventional PCI specification. PCI Express* configuration space is divided into a PCI-compatible region (that consists of the first 256 bytes of a logical device's configuration space) and an extended PCI Express* region (that consists of the remaining configuration space). The PCI-compatible region can be accessed using either the mechanisms defined in the PCI specification or using the enhanced PCI Express* configuration access mechanism described in the PCI Express* Enhanced Configuration Mechanism section. The PCI Express* Host Bridge is required to translate the memory-mapped PCI Express* configuration space accesses from the host processor to PCI Express* configuration cycles. To maintain compatibility with PCI configuration addressing mechanisms, it is recommended that system software access the enhanced configuration space using 32-bit operations (32-bit aligned) only. See the PCI Express Base Specification for details of both the PCI-compatible and PCI Express* Enhanced configuration mechanisms and transaction rules. PCI Express* Port The PCI Express* interface on the processor is a single, 16-lane (x16) port that can also be configured at narrower widths.

Upstream write transactions to addresses above 64 GB will be dropped. * Supports the following traffic types to or from the PCH: * -- DMI -> DRAM -- DMI -> processor core (Virtual Legacy Wires (VLWs), Resetwarn, or MSIs only) -- Processor core -> DMI APIC and MSI interrupt messaging support: -- Message Signaled Interrupt (MSI and MSI-X) messages * Downstream SMI, SCI and SERR error indication. * Legacy support for ISA regime protocol (PHOLD/PHOLDA) required for parallel port DMA, floppy drive, and LPC bus masters. * DC coupling - no capacitors between the processor and the PCH. * Polarity inversion. * PCH end-to-end lane reversal across the link. * Supports Half Swing "low-power/low-voltage". DMI Error Flow DMI can only generate SERR in response to errors, never SCI, SMI, MSI, PCI INT, or GPE. Any DMI related SERR activity is associated with Device 0. DMI Link Down The DMI link going down is a fatal, unrecoverable error. If the DMI data link goes to data link down, after the link was up, then the DMI link hangs the system by not allowing the link to retrain to prevent data corruption. This link behavior is controlled by the PCH. Downstream transactions that had been successfully transmitted across the link prior to the link going down may be processed as normal. No completions from downstream, non-posted transactions are returned upstream over the DMI link after a link down event.

All the cores are fully programmable, increasing the versatility of the 3D Engine. 3D Engine Execution Units * Supports up to 20 EUs.The EUs perform 128-bit wide execution per clock. * Support SIMD8 instructions for vertex processing and SIMD16 instructions for pixel processing. Vertex Fetch (VF) Stage The VF stage executes 3DPRIMITIVE commands. Some enhancements have been included to better support legacy D3D APIs as well as SGI OpenGL*. Desktop 4th Generation Intel(R) CoreTM Processor Family, Desktop Intel(R) Pentium(R) Processor Family, and Desktop Intel(R) Celeron(R) Processor Family March 2015 Datasheet - Volume 1 of 2 Order No.: 328897-010 29 Processor--Interfaces Vertex Shader (VS) Stage The VS stage performs shading of vertices output by the VF function. The VS unit produces an output vertex reference for every input vertex reference received from the VF unit, in the order received. Geometry Shader (GS) Stage The GS stage receives inputs from the VS stage. Compiled application-provided GS programs, specifying an algorithm to convert the vertices of an input object into some output primitives. For example, a GS shader may convert lines of a line strip into polygons representing a corresponding segment of a blade of grass centered on the line. Or it could use adjacency information to detect silhouette edges of triangles and output polygons extruding out from the edges. Clip Stage The Clip stage performs general processing on incoming 3D objects. However, it also includes specialized logic to perform a Clip Test function on incoming objects. The Clip Test optimizes generalized 3D Clipping. The Clip unit examines the position of incoming vertices, and accepts/rejects 3D objects based on its Clip algorithm. Strips and Fans (SF) Stage The SF stage performs setup operations required to rasterize 3D objects. The outputs from the SF stage to the Windower stage contain implementation-specific information required for the rasterization of objects and also supports clipping of primitives to some extent. Windower / IZ (WIZ) Stage The WIZ unit performs an early depth test, which removes failing pixels and eliminates unnecessary processing overhead. The Windower uses the parameters provided by the SF unit in the object-specific rasterization algorithms. The WIZ unit rasterizes objects into the corresponding set of pixels. The Windower is also capable of performing dithering, whereby the illusion of a higher resolution when using low-bpp channels in color buffers is possible. Color dithering diffuses the sharp color bands seen on smooth-shaded objects. Video Engine The Video Engine handles the non-3D (media/video) applications. It includes support for VLD and MPEG2 decode in hardware. 2D Engine The 2D Engine contains BLT (Block Level Transfer) functionality and an extensive set of 2D instructions. To take advantage of the 3D during engine's functionality, some BLT functions make use of the 3D renderer. Processor Graphics VGA Registers The 2D registers consists of original VGA registers and others to support graphics modes that have color depths, resolutions, and hardware acceleration features that go beyond the original VGA standard.

The 128-bit BLT engine provides hardware acceleration of block transfers of pixel data for many common Windows operations. The BLT engine can be used for the following: * Move rectangular blocks of data between memory locations * Data alignment * To perform logical operations (raster ops) The rectangular block of data does not change, as it is transferred between memory locations. The allowable memory transfers are between: cacheable system memory and frame buffer memory, frame buffer memory and frame buffer memory, and within system memory. Data to be transferred can consist of regions of memory, patterns, or solid color fills. A pattern is always 8 x 8 pixels wide and may be 8, 16, or 32 bits per pixel. The BLT engine expands monochrome data into a color depth of 8, 16, or 32 bits. BLTs can be either opaque or transparent. Opaque transfers move the data specified to the destination. Transparent transfers compare destination color to source color and write according to the mode of transparency selected. Data is horizontally and vertically aligned at the destination. If the destination for the BLT overlaps with the source memory location, the BLT engine specifies which area in memory to begin the BLT transfer. Hardware is included for all 256 raster operations (source, pattern, and destination) defined by Microsoft*, including transparent BLT. The BLT engine has instructions to invoke BLT and stretch BLT operations, permitting software to set up instruction buffers and use batch processing. The BLT engine can perform hardware clipping during BLTs. 2.5.2 Multi Graphics Controllers Multi-Monitor Support The processor supports simultaneous use of the Processor Graphics Controller (GT) and a x16 PCI Express* Graphics (PEG) device. The processor supports a maximum of 2 displays connected to the PEG card in parallel with up to 2 displays connected to the processor and PCH. Note: When supporting Multi Graphics Multi Monitors, "drag and drop" between monitors and the 2x8PEG is not supported. 2.6 Digital Display Interface (DDI) * The processor supports: -- Three Digital Display (x4 DDI) interfaces that can be configured as DisplayPort*, HDMI*, or DVI. DisplayPort* can be configured to use 1, 2, or 4 lanes depending on the bandwidth requirements and link data rate of RBR (1.62 GT/s), HBR (2.7 GT/s) and HBR2 (5.4 GT/s).

Refer to the HDMI section for more information on the signals and data transmission. To drive DVI-I through the back panel the VGA DDC signals are connected along with the digital data and clock signals from one of the Digital Ports. When a system has support for a DVI-I port, then either VGA or the DVI-D through a single DVI-I connector can be driven, but not both simultaneously.

The implementation of the features may vary between the processor SKUs. Details on the different technologies of Intel processors and other relevant external notes are located at the Intel technology web site: http://www.intel.com/technology/ 3.1 Intel(R) Virtualization Technology (Intel(R) VT) Intel(R) Virtualization Technology (Intel(R) VT) makes a single system appear as multiple independent systems to software. This allows multiple, independent operating systems to run simultaneously on a single system. Intel VT comprises technology components to support virtualization of platforms based on Intel architecture microprocessors and chipsets. Intel(R) Virtualization Technology (Intel(R) VT) for IA-32, Intel(R) 64 and Intel(R) Architecture (Intel(R) VT-x) added hardware support in the processor to improve the virtualization performance and robustness. Intel(R) Virtualization Technology for Directed I/O (Intel VT-d) extends Intel(R) VT-x by adding hardware assisted support to improve I/O device virtualization performance. Intel(R) VT-x specifications and functional descriptions are included in the Intel(R) 64 and IA-32 Architectures Software Developer's Manual, Volume 3B and is available at: http://www.intel.com/products/processor/manuals/index.htm The Intel VT-d specification and other Intel VT documents can be referenced at: http://www.intel.com/technology/virtualization/index.htm https://sharedspaces.intel.com/sites/PCDC/SitePages/Ingredients/ingredient.aspx? ing=VT Intel(R) VT-x Objectives Intel VT-x provides hardware acceleration for virtualization of IA platforms. Virtual Machine Monitor (VMM) can use Intel VT-x features to provide an improved reliable virtualized platform. By using Intel VT-x, a VMM is: * Robust: VMMs no longer need to use paravirtualization or binary translation. This means that off-the-shelf operating systems and applications can be run without any special steps. * Enhanced: Intel VT enables VMMs to run 64-bit guest operating systems on IA x86 processors. Desktop 4th Generation Intel(R) CoreTM Processor Family, Desktop Intel(R) Pentium(R) Processor Family, and Desktop Intel(R) Celeron(R) Processor Family March 2015 Datasheet - Volume 1 of 2 Order No.: 328897-010 39 Processor--Technologies * More reliable: Due to the hardware support, VMMs can now be smaller, less complex, and more efficient. This improves reliability and availability and reduces the potential for software conflicts. * More secure: The use of hardware transitions in the VMM strengthens the isolation of VMs and further prevents corruption of one VM from affecting others on the same system. Intel(R) VT-x Features The processor supports the following Intel VT-x features: * Extended Page Table (EPT) Accessed and Dirty Bits -- * Extended Page Table Pointer (EPTP) switching -- * EPT A/D bits enabled VMMs to efficiently implement memory management and page classification algorithms to optimize VM memory operations, such as defragmentation, paging, live migration, and check-pointing. Without hardware support for EPT A/D bits, VMMs may need to emulate A/D bits by marking EPT paging-structures as not-present or read-only, and incur the overhead of EPT page-fault VM exits and associated software processing. EPTP switching is a specific VM function. EPTP switching allows guest software (in VMX non-root operation, supported by EPT) to request a different EPT paging-structure hierarchy. This is a feature by which software in VMX nonroot operation can request a change of EPTP without a VM exit. Software can choose among a set of potential EPTP values determined in advance by software in VMX root operation. Pause loop exiting -- Support VMM schedulers seeking to determine when a virtual processor of a multiprocessor virtual machine is not performing useful work. This situation may occur when not all virtual processors of the virtual machine are currently scheduled and when the virtual processor in question is in a loop involving the PAUSE instruction. The new feature allows detection of such loops and is thus called PAUSE-loop exiting. The processor core supports the following Intel VT-x features: * * * Extended Page Tables (EPT) -- EPT is hardware assisted page table virtualization. -- It eliminates VM exits from the guest operating system to the VMM for shadow page-table maintenance. Virtual Processor IDs (VPID) -- Ability to assign a VM ID to tag processor core hardware structures (such as TLBs). -- This avoids flushes on VM transitions to give a lower-cost VM transition time and an overall reduction in virtualization overhead. Guest Preemption Timer -- Mechanism for a VMM to preempt the execution of a guest operating system after an amount of time specified by the VMM. The VMM sets a timer value before entering a guest. -- The feature aids VMM developers in flexibility and Quality of Service (QoS) guarantees.

Intel(R) VT-d Objectives The key Intel VT-d objectives are domain-based isolation and hardware-based virtualization. A domain can be abstractly defined as an isolated environment in a platform to which a subset of host physical memory is allocated. Intel VT-d provides accelerated I/O performance for a virtualized platform and provides software with the following capabilities: * I/O device assignment and security: for flexibly assigning I/O devices to VMs and extending the protection and isolation properties of VMs for I/O operations. * DMA remapping: for supporting independent address translations for Direct Memory Accesses (DMA) from devices. * Interrupt remapping: for supporting isolation and routing of interrupts from devices and external interrupt controllers to appropriate VMs. * Reliability: for recording and reporting to system software DMA and interrupt errors that may otherwise corrupt memory or impact VM isolation. Intel VT-d accomplishes address translation by associating a transaction from a given I/O device to a translation table associated with the Guest to which the device is assigned. It does this by means of the data structure in the following illustration. This table creates an association between the device's PCI Express* Bus/Device/Function (B/D/F) number and the base address of a translation table. This data structure is populated by a VMM to map devices to translation tables in accordance with the device assignment restrictions above, and to include a multi-level translation table (VT-d Table) that contains Guest specific address translations.

This might be in a chipset component or in the PCI Express functionality of a processor with integrated I/O. When one such Intel VT-d engine receives a PCI Express transaction from a PCI Express bus, it uses the B/D/F number associated with the transaction to search for an Intel VT-d translation table. In doing so, it uses the B/D/F number to traverse the data structure shown in the above figure. If it finds a valid Intel VT-d table in this data structure, it uses that table to translate the address provided on the PCI Express bus. If it does not find a valid translation table for a given translation, this results in an Intel VT-d fault. If Intel VT-d translation is required, the Intel VT-d engine performs an N-level table walk.

Note: Intel VT-d Technology may not be available on all SKUs. 3.2 Intel(R) Trusted Execution Technology (Intel(R) TXT) Intel Trusted Execution Technology (Intel TXT) defines platform-level enhancements that provide the building blocks for creating trusted platforms. The Intel TXT platform helps to provide the authenticity of the controlling environment such that those wishing to rely on the platform can make an appropriate trust decision. The Intel TXT platform determines the identity of the controlling environment by accurately measuring and verifying the controlling software. Desktop 4th Generation Intel(R) CoreTM Processor Family, Desktop Intel(R) Pentium(R) Processor Family, and Desktop Intel(R) Celeron(R) Processor Family March 2015 Datasheet - Volume 1 of 2 Order No.: 328897-010 43 Processor--Technologies Another aspect of the trust decision is the ability of the platform to resist attempts to change the controlling environment. The Intel TXT platform will resist attempts by software processes to change the controlling environment or bypass the bounds set by the controlling environment. Intel TXT is a set of extensions designed to provide a measured and controlled launch of system software that will then establish a protected environment for itself and any additional software that it may execute. These extensions enhance two areas: * The launching of the Measured Launched Environment (MLE). * The protection of the MLE from potential corruption. The enhanced platform provides these launch and control interfaces using Safer Mode Extensions (SMX). The SMX interface includes the following functions: * Measured/Verified launch of the MLE. * Mechanisms to ensure the above measurement is protected and stored in a secure location. * Protection mechanisms that allow the MLE to control attempts to modify itself. The processor also offers additional enhancements to System Management Mode (SMM) architecture for enhanced security and performance. The processor provides new MSRs to: * Enable a second SMM range * Enable SMM code execution range checking * Select whether SMM Save State is to be written to legacy SMRAM or to MSRs * Determine if a thread is going to be delayed entering SMM * Determine if a thread is blocked from entering SMM * Targeted SMI, enable/disable threads from responding to SMIs both VLWs and IPI For the above features, BIOS must test the associated capability bit before attempting to access any of the above registers. For more information, refer to the Intel(R) Trusted Execution Technology Measured Launched Environment Programming Guide. 3.3 Intel(R) Hyper-Threading Technology (Intel(R) HT Technology) The processor supports Intel Hyper-Threading Technology (Intel HT Technology) that allows an execution core to function as two logical processors. While some execution resources, such as caches, execution units, and buses are shared, each logical processor has its own architectural state with its own set of general-purpose registers and control registers. This feature must be enabled using the BIOS and requires operating system support. Desktop 4th Generation Intel(R) CoreTM Processor Family, Desktop Intel(R) Pentium(R) Processor Family, and Desktop Intel(R) Celeron(R) Processor Family Datasheet - Volume 1 of 2 March 2015 44 Order No.: 328897-010 Technologies--Processor Intel recommends enabling Intel HT Technology with Microsoft Windows* 8 and Microsoft Windows* 7 and disabling Intel HT Technology using the BIOS for all previous versions of Windows* operating systems. For more information on Intel HT Technology, see http://www.intel.com/technology/platform-technology/hyperthreading/. 3.4 Intel(R) Turbo Boost Technology 2.0 The Intel Turbo Boost Technology 2.0 allows the processor core to opportunistically and automatically run faster than its rated operating frequency/render clock, if it is operating below power, temperature, and current limits. The Intel Turbo Boost Technology 2.0 feature is designed to increase performance of both multi-threaded and single-threaded workloads. Maximum frequency is dependant on the SKU and number of active cores. No special hardware support is necessary for Intel Turbo Boost Technology 2.0. BIOS and the operating system can enable or disable Intel Turbo Boost Technology 2.0. Compared with previous generation products, Intel Turbo Boost Technology 2.0 will increase the ratio of application power to TDP. Thus, thermal solutions and platform cooling that are designed to less than thermal design guidance might experience thermal and performance issues since more applications will tend to run at the maximum power limit for significant periods of time. Note: Intel Turbo Boost Technology 2.0 may not be available on all SKUs. Intel(R) Turbo Boost Technology 2.0 Frequency The processor rated frequency assumes that all execution cores are running an application at the thermal design power (TDP). However, under typical operation, not all cores are active. Therefore, most applications are consuming less than the TDP at the rated frequency. To take advantage of the available thermal headroom, the active cores can increase their operating frequency. To determine the highest performance frequency amongst active cores, the processor takes the following into consideration: * The number of cores operating in the C0 state. * The estimated core current consumption. * The estimated package prior and present power consumption. * The package temperature. Any of these factors can affect the maximum frequency for a given workload. If the power, current, or thermal limit is reached, the processor will automatically reduce the frequency to stay within its TDP limit. Turbo processor frequencies are only active if the operating system is requesting the P0 state. For more information on P-states and C-states, see Power Management on page 49. 3.5 Intel(R) Advanced Vector Extensions 2.0 (Intel(R) AVX2) Intel Advanced Vector Extensions 2.0 (Intel AVX2) is the latest expansion of the Intel instruction set. Intel AVX2 extends the Intel Advanced Vector Extensions (Intel AVX) with 256-bit integer instructions, floating-point fused multiply add (FMA) instructions, and gather operations. The 256-bit integer vectors benefit math, codec, image, and Desktop 4th Generation Intel(R) CoreTM Processor Family, Desktop Intel(R) Pentium(R) Processor Family, and Desktop Intel(R) Celeron(R) Processor Family March 2015 Datasheet - Volume 1 of 2 Order No.: 328897-010 45 Processor--Technologies digital signal processing software. FMA improves performance in face detection, professional imaging, and high performance computing. Gather operations increase vectorization opportunities for many applications. In addition to the vector extensions, this generation of Intel processors adds new bit manipulation instructions useful in compression, encryption, and general purpose software. For more information on Intel AVX, see http://www.intel.com/software/avx 3.6 Intel(R) Advanced Encryption Standard New Instructions (Intel(R) AES-NI) The processor supports Intel Advanced Encryption Standard New Instructions (Intel AES-NI) that are a set of Single Instruction Multiple Data (SIMD) instructions that enable fast and secure data encryption and decryption based on the Advanced Encryption Standard (AES). Intel AES-NI are valuable for a wide range of cryptographic applications, such as applications that perform bulk encryption/ decryption, authentication, random number generation, and authenticated encryption. AES is broadly accepted as the standard for both government and industry applications, and is widely deployed in various protocols. Intel AES-NI consists of six Intel SSE instructions. Four instructions, AESENC, AESENCLAST, AESDEC, and AESDELAST facilitate high performance AES encryption and decryption. The other two, AESIMC and AESKEYGENASSIST, support the AES key expansion procedure. Together, these instructions provide a full hardware for supporting AES; offering security, high performance, and a great deal of flexibility. PCLMULQDQ Instruction The processor supports the carry-less multiplication instruction, PCLMULQDQ. PCLMULQDQ is a Single Instruction Multiple Data (SIMD) instruction that computes the 128-bit carry-less multiplication of two, 64-bit operands without generating and propagating carries. Carry-less multiplication is an essential processing component of several cryptographic systems and standards. Hence, accelerating carry-less multiplication can significantly contribute to achieving high speed secure computing and communication. Intel(R) Secure Key The processor supports Intel(R) Secure Key (formerly known as Digital Random Number Generator (DRNG)), a software visible random number generation mechanism supported by a high quality entropy source. This capability is available to programmers through the RDRAND instruction. The resultant random number generation capability is designed to comply with existing industry standards in this regard (ANSI X9.82 and NIST SP 800-90). Some possible usages of the RDRAND instruction include cryptographic key generation as used in a variety of applications, including communication, digital signatures, secure storage, and so on. 3.7 Intel(R) Transactional Synchronization Extensions - New Instructions (Intel(R) TSX-NI) Intel Transactional Synchronization Extensions - New Instructions (Intel TSX-NI). Intel TSX-NI provides a set of instruction extensions that allow programmers to specify regions of code for transactional synchronization. Programmers can use these Desktop 4th Generation Intel(R) CoreTM Processor Family, Desktop Intel(R) Pentium(R) Processor Family, and Desktop Intel(R) Celeron(R) Processor Family Datasheet - Volume 1 of 2 March 2015 46 Order No.: 328897-010 Technologies--Processor extensions to achieve the performance of fine-grain locking while actually programming using coarse-grain locks. Details on Intel TSX-NI are in the Intel(R) Architecture Instruction Set Extensions Programming Reference. 3.8 Intel(R) 64 Architecture x2APIC The x2APIC architecture extends the xAPIC architecture that provides key mechanisms for interrupt delivery. This extension is primarily intended to increase processor addressability. Specifically, x2APIC: * Retains all key elements of compatibility to the xAPIC architecture: -- Delivery modes -- Interrupt and processor priorities -- Interrupt sources -- Interrupt destination types * Provides extensions to scale processor addressability for both the logical and physical destination modes * Adds new features to enhance performance of interrupt delivery * Reduces complexity of logical destination mode interrupt delivery on link based architectures The key enhancements provided by the x2APIC architecture over xAPIC are the following: * * * Support for two modes of operation to provide backward compatibility and extensibility for future platform innovations: -- In xAPIC compatibility mode, APIC registers are accessed through memory mapped interface to a 4K-Byte page, identical to the xAPIC architecture. -- In x2APIC mode, APIC registers are accessed through Model Specific Register (MSR) interfaces. In this mode, the x2APIC architecture provides significantly increased processor addressability and some enhancements on interrupt delivery. Increased range of processor addressability in x2APIC mode: -- Physical xAPIC ID field increases from 8 bits to 32 bits, allowing for interrupt processor addressability up to 4G-1 processors in physical destination mode. A processor implementation of x2APIC architecture can support fewer than 32bits in a software transparent fashion. -- Logical xAPIC ID field increases from 8 bits to 32 bits. The 32-bit logical x2APIC ID is partitioned into two sub-fields - a 16-bit cluster ID and a 16-bit logical ID within the cluster. Consequently, ((2^20) - 16) processors can be addressed in logical destination mode. Processor implementations can support fewer than 16 bits in the cluster ID sub-field and logical ID sub-field in a software agnostic fashion. More efficient MSR interface to access APIC registers: -- To enhance inter-processor and self-directed interrupt delivery as well as the ability to virtualize the local APIC, the APIC register set can be accessed only through MSR-based interfaces in x2APIC mode. The Memory Mapped IO (MMIO) interface used by xAPIC is not supported in x2APIC mode. Desktop 4th Generation Intel(R) CoreTM Processor Family, Desktop Intel(R) Pentium(R) Processor Family, and Desktop Intel(R) Celeron(R) Processor Family March 2015 Datasheet - Volume 1 of 2 Order No.: 328897-010 47 Processor--Technologies Note: * The semantics for accessing APIC registers have been revised to simplify the programming of frequently-used APIC registers by system software. Specifically, the software semantics for using the Interrupt Command Register (ICR) and End Of Interrupt (EOI) registers have been modified to allow for more efficient delivery and dispatching of interrupts. * The x2APIC extensions are made available to system software by enabling the local x2APIC unit in the "x2APIC" mode. To benefit from x2APIC capabilities, a new operating system and a new BIOS are both needed, with special support for x2APIC mode. * The x2APIC architecture provides backward compatibility to the xAPIC architecture and forward extendible for future Intel platform innovations. Intel x2APIC Technology may not be available on all SKUs. For more information, see the Intel(R) 64 Architecture x2APIC Specification at http:// www.intel.com/products/processor/manuals/. 3.9 Power Aware Interrupt Routing (PAIR) The processor includes enhanced power-performance technology that routes interrupts to threads or cores based on their sleep states. As an example, for energy savings, it routes the interrupt to the active cores without waking the deep idle cores. For performance, it routes the interrupt to the idle (C1) cores without interrupting the already heavily loaded cores. This enhancement is mostly beneficial for high-interrupt scenarios like Gigabit LAN, WLAN peripherals, and so on. 3.10 Execute Disable Bit The Execute Disable Bit allows memory to be marked as executable when combined with a supporting operating system. If code attempts to run in non-executable memory, the processor raises an error to the operating system. This feature can prevent some classes of viruses or worms that exploit buffer overrun vulnerabilities and can thus help improve the overall security of the system. See the Intel(R) 64 and IA-32 Architectures Software Developer's Manuals for more detailed information. 3.11 Supervisor Mode Execution Protection (SMEP) Supervisor Mode Execution Protection provides the next level of system protection by blocking malicious software attacks from user mode code when the system is running in the highest privilege level. This technology helps to protect from virus attacks and unwanted code from harming the system.

Processor Core Power Management (R) While executing code, Enhanced Intel SpeedStep Technology optimizes the processor's frequency and core voltage based on workload. Each frequency and voltage operating point is defined by ACPI as a P-state. When the processor is not executing code, it is idle. A low-power idle state is defined by ACPI as a C-state. In general, deeper power C-states have longer entry and exit latencies. 4.2.1 Enhanced Intel(R) SpeedStep(R) Technology Key Features The following are the key features of Enhanced Intel SpeedStep Technology: Desktop 4th Generation Intel(R) CoreTM Processor Family, Desktop Intel(R) Pentium(R) Processor Family, and Desktop Intel(R) Celeron(R) Processor Family March 2015 Datasheet - Volume 1 of 2 Order No.: 328897-010 51 Processor--Power Management 4.2.2 * Multiple frequency and voltage points for optimal performance and power efficiency. These operating points are known as P-states. * Frequency selection is software controlled by writing to processor MSRs. The voltage is optimized based on the selected frequency and the number of active processor cores. -- Once the voltage is established, the PLL locks on to the target frequency. -- All active processor cores share the same frequency and voltage. In a multicore processor, the highest frequency P-state requested among all active cores is selected. -- Software-requested transitions are accepted at any time. If a previous transition is in progress, the new transition is deferred until the previous transition is completed. * The processor controls voltage ramp rates internally to ensure glitch-free transitions. * Because there is low transition latency between P-states, a significant number of transitions per-second are possible. Low-Power Idle States When the processor is idle, low-power idle states (C-states) are used to save power. More power savings actions are taken for numerically higher C-states. However, higher C-states have longer exit and entry latencies. Resolution of C-states occur at the thread, processor core, and processor package level. Thread-level C-states are available if Intel Hyper-Threading Technology is enabled. Caution: Long term reliability cannot be assured unless all the Low-Power Idle States are enabled. Figure 12. Idle Power Management Breakdown of the Processor Cores Thread 0 Thread 1 Thread 0 Core 0 State Thread 1 Core N State Processor Package State Entry and exit of the C-states at the thread and core level are shown in the following figure.

Core C-states are automatically resolved by the processor. For thread and core C-states, a transition to and from C0 is required before entering any other C-state. Table 18.

If enabled, the core C-state will be C1E if all cores have resolved a core C1 state or higher. 4.2.3 Requesting Low-Power Idle States The primary software interfaces for requesting low-power idle states are through the MWAIT instruction with sub-state hints and the HLT instruction (for C1 and C1E). However, software may make C-state requests using the legacy method of I/O reads from the ACPI-defined processor clock control registers, referred to as P_LVLx. This method of requesting C-states provides legacy support for operating systems that initiate C-state transitions using I/O reads. For legacy operating systems, P_LVLx I/O reads are converted within the processor to the equivalent MWAIT C-state request. Therefore, P_LVLx reads do not directly result in I/O reads to the system. The feature, known as I/O MWAIT redirection, must be enabled in the BIOS. The BIOS can write to the C-state range field of the PMG_IO_CAPTURE MSR to restrict the range of I/O addresses that are trapped and emulate MWAIT like functionality. Any P_LVLx reads outside of this range do not cause an I/O redirection to MWAIT(Cx) like request. The reads fall through like a normal I/O instruction. Desktop 4th Generation Intel(R) CoreTM Processor Family, Desktop Intel(R) Pentium(R) Processor Family, and Desktop Intel(R) Celeron(R) Processor Family March 2015 Datasheet - Volume 1 of 2 Order No.: 328897-010 53 Processor--Power Management Note: When P_LVLx I/O instructions are used, MWAIT sub-states cannot be defined. The MWAIT sub-state is always zero if I/O MWAIT redirection is used. By default, P_LVLx I/O redirections enable the MWAIT 'break on EFLAGS.IF' feature that triggers a wakeup on an interrupt, even if interrupts are masked by EFLAGS.IF. 4.2.4 Core C-State Rules The following are general rules for all core C-states, unless specified otherwise: * A core C-state is determined by the lowest numerical thread state (such as Thread 0 requests C1E state while Thread 1 requests C3 state, resulting in a core C1E state). See the G, S, and C Interface State Combinations table. * A core transitions to C0 state when: -- An interrupt occurs -- There is an access to the monitored address if the state was entered using an MWAIT/Timed MWAIT instruction -- The deadline corresponding to the Timed MWAIT instruction expires * An interrupt directed toward a single thread wakes only that thread. * If any thread in a core is in active (in C0 state), the core's C-state will resolve to C0 state. * Any interrupt coming into the processor package may wake any core. * A system reset re-initializes all processor cores. Core C0 State The normal operating state of a core where code is being executed. Core C1/C1E State C1/C1E is a low power state entered when all threads within a core execute a HLT or MWAIT(C1/C1E) instruction. A System Management Interrupt (SMI) handler returns execution to either Normal state or the C1/C1E state. See the Intel(R) 64 and IA-32 Architectures Software Developer's Manual for more information. While a core is in C1/C1E state, it processes bus snoops and snoops from other threads. For more information on C1E state, see Package C-States on page 55. Core C3 State Individual threads of a core can enter the C3 state by initiating a P_LVL2 I/O read to the P_BLK or an MWAIT(C3) instruction. A core in C3 state flushes the contents of its L1 instruction cache, L1 data cache, and L2 cache to the shared L3 cache, while maintaining its architectural state. All core clocks are stopped at this point. Because the core's caches are flushed, the processor does not wake any core that is in the C3 state when either a snoop is detected or when another core accesses cacheable memory. Desktop 4th Generation Intel(R) CoreTM Processor Family, Desktop Intel(R) Pentium(R) Processor Family, and Desktop Intel(R) Celeron(R) Processor Family Datasheet - Volume 1 of 2 March 2015 54 Order No.: 328897-010 Power Management--Processor Core C6 State Individual threads of a core can enter the C6 state by initiating a P_LVL3 I/O read or an MWAIT(C6) instruction. Before entering core C6 state, the core will save its architectural state to a dedicated SRAM. Once complete, a core will have its voltage reduced to zero volts. During exit, the core is powered on and its architectural state is restored. Core C7 State Individual threads of a core can enter the C7 state by initiating a P_LVL4 I/O read to the P_BLK or by an MWAIT(C7) instruction. The core C7 state exhibits the same behavior as the core C6 state. Note: C7 state may not be available on all SKUs. C-State Auto-Demotion In general, deeper C-states, such as C6 state, have long latencies and have higher energy entry/exit costs. The resulting performance and energy penalties become significant when the entry/exit frequency of a deeper C-state is high. Therefore, incorrect or inefficient usage of deeper C-states have a negative impact on idle power. To increase residency and improve idle power in deeper C-states, the processor supports C-state auto-demotion. There are two C-state auto-demotion options: * C7/C6 to C3 state * C7/C6/C3 To C1 state The decision to demote a core from C6/C7 to C3 or C3/C6/C7 to C1 state is based on each core's immediate residency history and interrupt rate . If the interrupt rate experienced on a core is high and the residence in a deep C-state between such interrupts is low, the core can be demoted to a C3 or C1 state. A higher interrupt pattern is required to demote a core to C1 state as compared to C3 state. This feature is disabled by default. BIOS must enable it in the PMG_CST_CONFIG_CONTROL register. The auto-demotion policy is also configured by this register. 4.2.5 Package C-States The processor supports C0, C1/C1E, C3, C6, and C7 (on some SKUs) power states. The following is a summary of the general rules for package C-state entry. These apply to all package C-states, unless specified otherwise: * A package C-state request is determined by the lowest numerical core C-state amongst all cores. * A package C-state is automatically resolved by the processor depending on the core idle power states and the status of the platform components. -- Each core can be at a lower idle power state than the package if the platform does not grant the processor permission to enter a requested package C-state. -- The platform may allow additional power savings to be realized in the processor.

The processor exits a package C-state when a break event is detected. Depending on the type of break event, the processor does the following: * * If a core break event is received, the target core is activated and the break event message is forwarded to the target core. -- If the break event is not masked, the target core enters the core C0 state and the processor enters package C0 state. -- If the break event is masked, the processor attempts to re-enter its previous package state. If the break event was due to a memory access or snoop request, -- But the platform did not request to keep the processor in a higher package Cstate, the package returns to its previous C-state. -- And the platform requests a higher power C-state, the memory access or snoop request is serviced and the package remains in the higher power Cstate. The following table shows package C-state resolution for a dual-core processor. The following figure summarizes package C-state transitions. Table 19.

Package C-State Entry and Exit C0 C3 C6 C1 C7 Package C0 State This is the normal operating state for the processor. The processor remains in the normal state when at least one of its cores is in the C0 or C1 state or when the platform has not granted permission to the processor to go into a low-power state. Individual cores may be in lower power idle states while the package is in C0 state. Package C1/C1E State No additional power reduction actions are taken in the package C1 state. However, if the C1E sub-state is enabled, the processor automatically transitions to the lowest supported core clock frequency, followed by a reduction in voltage. The package enters the C1 low-power state when: * At least one core is in the C1 state. * The other cores are in a C1 or deeper power state. The package enters the C1E state when: * All cores have directly requested C1E using MWAIT(C1) with a C1E sub-state hint. * All cores are in a power state deeper than C1/C1E state; however, the package low-power state is limited to C1/C1E using the PMG_CST_CONFIG_CONTROL MSR. * All cores have requested C1 state using HLT or MWAIT(C1) and C1E autopromotion is enabled in IA32_MISC_ENABLES. No notification to the system occurs upon entry to C1/C1E state.

A processor enters Package C2 state when: * All cores and graphics have requested a C3 or deeper power state; however, constraints (LTR, programmed timer events in the near future, and so on) prevent entry to any state deeper than C 2 state. Or, * All cores and graphics are in the C3 or deeper power states, and a memory access request is received. Upon completion of all outstanding memory requests, the processor transitions back into a deeper package C-state. Package C3 State A processor enters the package C3 low-power state when: * At least one core is in the C3 state. * The other cores are in a C3 state or deeper power state and the processor has been granted permission by the platform. * The platform has not granted a request to a package C6 or deeper state, however, has allowed a package C6 state. In package C3 state, the L3 shared cache is valid. Package C6 State A processor enters the package C6 low-power state when: * At least one core is in the C6 state. * The other cores are in a C6 or deeper power state and the processor has been granted permission by the platform. * If the cores are requesting C7 state, but the platform is limiting to a package C6 state, the last level cache in this case can be flushed. In package C6 state all cores have saved their architectural state and have had their core voltages reduced to zero volts. It is possible the L3 shared cache is flushed and turned off in package C6 state. If at least one core is requesting C6 state, the L3 cache will not be flushed. Package C7 State The processor enters the package C7 low-power state when all cores are in the C7 state. In package C7, the processor will take action to remove power from portions of the system agent. Core break events are handled the same way as in package C3 or C6 state. Note: C7 state may not be available on all SKUs.

Package C7 state is the deepest C-state supported on integrated graphics systems (or switchable graphics systems during integrated graphics mode). However, in most configurations, package C6 will be more energy efficient than package C7 state. As a result, package C7 state residency is expected to be very low or zero in most scenarios where the display is enabled. Logic internal to the processor will determine whether package C6 or package C7 state is the most efficient. There is no need to make changes in BIOS or system software to prioritize package C6 state over package C7 state. 4.2.6 Package C-States and Display Resolutions The integrated graphics engine has the frame buffer located in system memory. When the display is updated, the graphics engine fetches display data from system memory. Different screen resolutions and refresh rates have different memory latency requirements. These requirements may limit the deepest Package C-state the processor can enter. Other elements that may affect the deepest Package C-state available are the following: Note: * Display is on or off * Single or multiple displays * Native or non-native resolution * Panel Self Refresh (PSR) technology Display resolution is not the only factor influencing the deepest Package C-state the processor can get into. Device latencies, interrupt response latencies, and core Cstates are among other factors that influence the final package C-state the processor can enter. The following table lists display resolutions and deepest available package C-State. The display resolutions are examples using common values for blanking and pixel rate. Actual results will vary. The table shows the deepest possible Package C-state. System workload, system idle, and AC or DC power also affect the deepest possible Package C-state. Table 20.

For multiple display cases, the resolution listed is the highest native resolution of all enabled displays, and PSR is internally disabled; that is, dual display with one 800x600 60 Hz display and one 2560x1600 60 Hz display will result in a deepest available package C-state of PC2. 2. Microcode Update rev 00000010 or newer must be used. 4.3 Integrated Memory Controller (IMC) Power Management The main memory is power managed during normal operation and in low-power ACPI Cx states. 4.3.1 Disabling Unused System Memory Outputs Any system memory (SM) interface signal that goes to a memory module connector in which it is not connected to any actual memory devices (such as SO-DIMM connector is unpopulated, or is single-sided) is tri-stated. The benefits of disabling unused SM signals are: * Reduced power consumption. Desktop 4th Generation Intel(R) CoreTM Processor Family, Desktop Intel(R) Pentium(R) Processor Family, and Desktop Intel(R) Celeron(R) Processor Family Datasheet - Volume 1 of 2 March 2015 60 Order No.: 328897-010 Power Management--Processor * Reduced possible overshoot/undershoot signal quality issues seen by the processor I/O buffer receivers caused by reflections from potentially unterminated transmission lines. When a given rank is not populated, the corresponding chip select and CKE signals are not driven. At reset, all rows must be assumed to be populated, until it can be determined that the rows are not populated. This is due to the fact that when CKE is tri-stated with an SO-DIMM present, the SO-DIMM is not ensured to maintain data integrity. CKE tri-state should be enabled by BIOS where appropriate, since at reset all rows must be assumed to be populated. 4.3.2 DRAM Power Management and Initialization The processor implements extensive support for power management on the SDRAM interface. There are four SDRAM operations associated with the Clock Enable (CKE) signals, which the SDRAM controller supports. The processor drives four CKE pins to perform these operations. The CKE is one of the power save means. When CKE is off, the internal DDR clock is disabled and the DDR power is reduced. The power saving differs according to the selected mode and the DDR type used. For more information, refer to the IDD table in the DDR specification. The processor supports three different types of power-down modes in package C0. The different power-down modes can be enabled through configuring "PM_PDWN_config_0_0_0_MCHBAR". The type of CKE power-down can be configured through PDWN_mode (bits 15:12) and the idle timer can be configured through PDWN_idle_counter (bits 11:0). The different power-down modes supported are: * No power-down (CKE disable) * Active power-down (APD): This mode is entered if there are open pages when de-asserting CKE. In this mode the open pages are retained. Power-saving in this mode is the lowest. Power consumption of DDR is defined by IDD3P. Exiting this mode is defined by tXP - small number of cycles. For this mode, DRAM DLL must be on. * PPD/DLL-off: In this mode the data-in DLLs on DDR are off. Power-saving in this mode is the best among all power modes. Power consumption is defined by IDD2P1. Exiting this mode is defined by tXP, but also tXPDLL (10-20 according to DDR type) cycles until first data transfer is allowed. For this mode, DRAM DLL must be off. The CKE is determined per rank, whenever it is inactive. Each rank has an idlecounter. The idle-counter starts counting as soon as the rank has no accesses, and if it expires, the rank may enter power-down while no new transactions to the rank arrives to queues. The idle-counter begins counting at the last incoming transaction arrival. It is important to understand that since the power-down decision is per rank, the IMC can find many opportunities to power down ranks, even while running memory intensive applications; the savings are significant (may be few Watts, according to the DDR specification). This is significant when each channel is populated with more ranks. Desktop 4th Generation Intel(R) CoreTM Processor Family, Desktop Intel(R) Pentium(R) Processor Family, and Desktop Intel(R) Celeron(R) Processor Family March 2015 Datasheet - Volume 1 of 2 Order No.: 328897-010 61 Processor--Power Management Selection of power modes should be according to power-performance or thermal trade-offs of a given system: * When trying to achieve maximum performance and power or thermal consideration is not an issue - use no power-down * In a system which tries to minimize power-consumption, try using the deepest power-down mode possible - PPD/DLL-off with a low idle timer value. * In high-performance systems with dense packaging (that is, tricky thermal design) the power-down mode should be considered in order to reduce the heating and avoid DDR throttling caused by the heating. The default value that BIOS configures in "PM_PDWN_config_0_0_0_MCHBAR" is 6080h; that is, PPD/DLL-off mode with idle timer of 80h, or 128 DCLKs. This is a balanced setting with deep power-down mode and moderate idle timer value. The idle timer expiration count defines the number of DCKLs that a rank is idle that causes entry to the selected power mode. As this timer is set to a shorter time, the IMC will have more opportunities to put DDR in power-down. There is no BIOS hook to set this register. Customers choosing to change the value of this register can do it by changing it in the BIOS. For experiments, this register can be modified in real time if BIOS does not lock the IMC registers. 4.3.2.1 Initialization Role of CKE During power-up, CKE is the only input to the SDRAM that has its level recognized (other than the DDR3/DDR3L reset pin) once power is applied. It must be driven LOW by the DDR controller to make sure the SDRAM components float DQ and DQS during power-up. CKE signals remain LOW (while any reset is active) until the BIOS writes to a configuration register. Using this method, CKE is ensured to remain inactive for much longer than the specified 200 micro-seconds after power and clocks to SDRAM devices are stable. 4.3.2.2 Conditional Self-Refresh During S0 idle state, system memory may be conditionally placed into self-refresh state when the processor is in package C3 or deeper power state. Refer to Intel(R) Rapid Memory Power Management (Intel(R) RMPM) for more details on conditional selfrefresh with Intel HD Graphics enabled. When entering the S3 - Suspend-to-RAM (STR) state or S0 conditional self-refresh, the processor core flushes pending cycles and then enters SDRAM ranks that are not used by Intel graphics memory into self-refresh. The CKE signals remain LOW so the SDRAM devices perform self-refresh. The target behavior is to enter self-refresh for package C3 or deeper power states as long as there are no memory requests to service. 4.3.2.3 Dynamic Power-Down Dynamic power-down of memory is employed during normal operation. Based on idle conditions, a given memory rank may be powered down. The IMC implements aggressive CKE control to dynamically put the DRAM devices in a power-down state. The processor core controller can be configured to put the devices in active powerdown (CKE de-assertion with open pages) or pre-charge power-down (CKE de- Desktop 4th Generation Intel(R) CoreTM Processor Family, Desktop Intel(R) Pentium(R) Processor Family, and Desktop Intel(R) Celeron(R) Processor Family Datasheet - Volume 1 of 2 March 2015 62 Order No.: 328897-010 Power Management--Processor assertion with all pages closed). Pre-charge power-down provides greater power savings, but has a bigger performance impact since all pages will first be closed before putting the devices in power-down mode. If dynamic power-down is enabled, all ranks are powered up before doing a refresh cycle and all ranks are powered down at the end of refresh. 4.3.2.4 DRAM I/O Power Management Unused signals should be disabled to save power and reduce electromagnetic interference. This includes all signals associated with an unused memory channel. Clocks, CKE, ODE, and CS signals are controlled per DIMM rank and will be powered down for unused ranks. The I/O buffer for an unused signal should be tri-stated (output driver disabled), the input receiver (differential sense-amp) should be disabled, and any DLL circuitry related ONLY to unused signals should be disabled. The input path must be gated to prevent spurious results due to noise on the unused signals (typically handled automatically when input receiver is disabled). 4.3.3 DRAM Running Average Power Limitation (RAPL) RAPL is a power and time constant pair. DRAM RAPL defines an average power constraint for the DRAM domain. Constraint is controlled by the PCU. Platform entities (PECI or in-band power driver) can specify a power limit for the DRAM domain. PCU continuously monitors the extant of DRAM throttling due to the power limit and rebudgets the limit between DIMMs. 4.3.4 DDR Electrical Power Gating (EPG) The DDR I/O of the processor supports Electrical Power Gating (DDR-EPG) while the processor is at C3 or deeper power state. In C3 or deeper power state, the processor internally gates VDDQ for the majority of the logic to reduce idle power while keeping all critical DDR pins such as SM_DRAMRST#, CKE and VREF in the appropriate state. In C7, the processor internally gates VCCIO_TERM for all non-critical state to reduce idle power. In S3 or C-state transitions, the DDR does not go through training mode and will restore the previous training information. 4.4 4.5 PCI Express* Power Management * Active power management is supported using L0s, and L1 states. * All inputs and outputs disabled in L2/L3 Ready state. Direct Media Interface (DMI) Power Management Active power management is supported using L0s/L1 state.

Intel RMPM functionality depends on graphics/display state (relevant only when processor graphics is being used), as well as memory traffic patterns generated by other connected I/O devices. 4.6.2 Graphics Render C-State Render C-state (RC6) is a technique designed to optimize the average power to the graphics render engine during times of idleness. RC6 is entered when the graphics render engine, blitter engine, and the video engine have no workload being currently worked on and no outstanding graphics memory transactions. When the idleness condition is met, the processor graphics will program the graphics render engine internal power rail into a low voltage state. 4.6.3 Intel(R) Graphics Dynamic Frequency Intel Graphics Dynamic Frequency Technology is the ability of the processor and graphics cores to opportunistically increase frequency and/or voltage above the guaranteed processor and graphics frequency for the given part. Intel Graphics Dynamic Frequency Technology is a performance feature that makes use of unused package power and thermals to increase application performance. The increase in frequency is determined by how much power and thermal budget is available in the package, and the application demand for additional processor or graphics performance. The processor core control is maintained by an embedded controller. The graphics driver dynamically adjusts between P-States to maintain optimal performance, power, and thermals. The graphics driver will always try to place the graphics engine in the most energy efficient P-state. Desktop 4th Generation Intel(R) CoreTM Processor Family, Desktop Intel(R) Pentium(R) Processor Family, and Desktop Intel(R) Celeron(R) Processor Family Datasheet - Volume 1 of 2 March 2015 64 Order No.: 328897-010 Thermal Management--Processor 5.0 Thermal Management This chapter provides both component-level and system-level thermal management. Topics covered include processor thermal specifications, thermal profiles, thermal metrology, fan speed control, adaptive thermal monitor, THERMTRIP# signal, Digital Thermal Sensor (DTS), Intel Turbo Boost Technology, package power control, power plane control, and turbo time parameter. The processor requires a thermal solution to maintain temperatures within its operating limits. Any attempt to operate the processor outside these operating limits may result in permanent damage to the processor and potentially other components within the system. Maintaining the proper thermal environment is key to reliable, long-term system operation. A complete solution includes both component and system level thermal management features. Component level thermal solutions can include active or passive heatsinks attached to the processor integrated heat spreader (IHS). To allow the optimal operation and long-term reliability of Intel processor-based systems, the processor must remain within the minimum and maximum case temperature (TCASE) specifications as defined by the applicable thermal profile. Thermal solutions not designed to provide this level of thermal capability may affect the long-term reliability of the processor and system. The processors implement a methodology for managing processor temperatures that is intended to support acoustic noise reduction through fan speed control and to assure processor reliability. Selection of the appropriate fan speed is based on the relative temperature data reported by the processor's Digital Temperature Sensor (DTS). The DTS can be read using the Platform Environment Control Interface (PECI) as described in Processor Temperature on page 78. Alternatively, when PECI is monitored by the PCH, the processor temperature can be read from the PCH using the SMBus protocol defined in Embedded Controller Support Provided by the PCH. The temperature reported over PECI is always a negative value and represents a delta below the onset of thermal control circuit (TCC) activation, as indicated by PROCHOT# (see Processor Temperature on page 78). Systems that implement fan speed control must be designed to use this data. Systems that do not alter the fan speed only need to ensure the case temperature meets the thermal profile specifications. Analysis indicates that real applications are unlikely to cause the processor to consume maximum power dissipation for sustained time periods. Intel recommends that complete thermal solution designs target the Thermal Design Power (TDP), instead of the maximum processor power consumption. The Adaptive Thermal Monitor feature is intended to help protect the processor in the event that an application exceeds the TDP recommendation for a sustained time period. For more details on this feature, see Adaptive Thermal Monitor on page 78. To ensure maximum flexibility for future processors, systems should be designed to the Thermal Solution Capability guidelines, even if a processor with lower power dissipation is currently planned.

The vendor part number is XTMS1565. 5.3 Fan Speed Control Scheme with Digital Thermal Sensor (DTS) 1.1 To correctly use DTS 1.1, the designer must first select a worst case scenario TAMBIENT, and ensure that the Fan Speed Control (FSC) can provide a CA that is equivalent or greater than the CA specification. The DTS 1.1 implementation consists of two points: a CA at TCONTROL and a CA at DTS = -1. Desktop 4th Generation Intel(R) CoreTM Processor Family, Desktop Intel(R) Pentium(R) Processor Family, and Desktop Intel(R) Celeron(R) Processor Family March 2015 Datasheet - Volume 1 of 2 Order No.: 328897-010 73 Processor--Thermal Management The CA point at DTS = -1 defines the minimum CA required at TDP considering the worst case system design TAMBIENT design point: CA = (TCASE-MAX - TAMBIENT-TARGET) / TDP For example, for a 95 W TDP part, the Tcase maximum is 72.6 C and at a worst case design point of 40 C local ambient this will result in: CA = (72.6 - 40) / 95 = 0.34 C/W Similarly for a system with a design target of 45 C ambient, the CA at DTS = -1 needed will be 0.29 C/W. The second point defines the thermal solution performance (CA) at TCONTROL. The following table lists the required CA for the various TDP processors. These two points define the operational limits for the processor for DTS 1.1 implementation. At TCONTROL the fan speed must be programmed such that the resulting CA is better than or equivalent to the required CA listed in the following table. Similarly, the fan speed should be set at DTS = -1 such that the thermal solution performance is better than or equivalent to the CA requirements at TAMBIENTMAX. The fan speed controller must linearly ramp the fan speed from processor DTS = TCONTROL to processor DTS = -1. Figure 20.

CA at "DTS = TCONTROL" is applicable to systems that have an internal TRISE (TROOM temperature to Processor cooling fan inlet) of less than 10 C. In case the expected TRISE is greater than 10 C, a correction factor should be used as explained below. For each 1 C TRISE above 10 C, the correction factor (CF) is defined as CF = 1.7 / (processor TDP) 2. Example: A chassis TRISE assumption is 12 C for a 95 W TDP processor: CF = 1.7 / 95 W = 0.018 /W For TRISE > 10 C CA at TCONTROL = (Value provide in Column 2) - (TRISE - 10) * CF CA = 0.627 - (12 - 10) * 0.018 = 0.591 C/W In this case, the fan speed should be set slightly higher, equivalent to CA = 0.591 C/W 5.4 Fan Speed Control Scheme with Digital Thermal Sensor (DTS) 2.0 To simplify processor thermal specification compliance, the processor calculates the DTS Thermal Profile from TCONTROL Offset, TCC Activation Temperature, TDP, and the Thermal Margin Slope provided in the following table. Note: TCC Activation Offset is 0 for the processors. Using the DTS Thermal Profile, the processor can calculate and report the Thermal Margin, where a value less than 0 indicates that the processor needs additional cooling, and a value greater than 0 indicates that the processor is sufficiently cooled.

Desktop 4th Generation Intel(R) CoreTM Processor Family, Desktop Intel(R) Pentium(R) Processor Family, and Desktop Intel(R) Celeron(R) Processor Family March 2015 Datasheet - Volume 1 of 2 Order No.: 328897-010 77 Processor--Thermal Management 5.6 Processor Temperature A software readable field in the TEMPERATURE_TARGET register contains the minimum temperature at which the TCC will be activated and PROCHOT# will be asserted. The TCC activation temperature is calibrated on a part-by-part basis and normal factory variation may result in the actual TCC activation temperature being higher than the value listed in the register. TCC activation temperatures may change based on processor stepping, frequency or manufacturing efficiencies. 5.7 Adaptive Thermal Monitor The Adaptive Thermal Monitor feature provides an enhanced method for controlling the processor temperature when the processor silicon exceeds the Thermal Control Circuit (TCC) activation temperature. Adaptive Thermal Monitor uses TCC activation to reduce processor power using a combination of methods. The first method (Frequency control, similar to Thermal Monitor 2 (TM2) in previous generation processors) involves the processor reducing its operating frequency (using the core ratio multiplier) and internal core voltage. This combination of lower frequency and core voltage results in a reduction of the processor power consumption. The second method (clock modulation, known as Thermal Monitor 1 or TM1 in previous generation processors) reduces power consumption by modulating (starting and stopping) the internal processor core clocks. The processor intelligently selects the appropriate TCC method to use on a dynamic basis. BIOS is not required to select a specific method (as with previous-generation processors supporting TM1 or TM2). The temperature at which Adaptive Thermal Monitor activates the Thermal Control Circuit is factory calibrated and is not user configurable. Snooping and interrupt processing are performed in the normal manner while the TCC is active. When the TCC activation temperature is reached, the processor will initiate TM2 in attempt to reduce its temperature. If TM2 is unable to reduce the processor temperature, TM1 will be also be activated. TM1 and TM2 will work together (clocks will be modulated at the lowest frequency ratio) to reduce power dissipation and temperature. With a properly designed and characterized thermal solution, it is anticipated that the TCC will only be activated for very short periods of time when running the most power intensive applications. The processor performance impact due to these brief periods of TCC activation is expected to be so minor that it would be immeasurable. An underdesigned thermal solution that is not able to prevent excessive activation of the TCC in the anticipated ambient environment may cause a noticeable performance loss, and in some cases may result in a TCASE that exceeds the specified maximum temperature and may affect the long-term reliability of the processor. In addition, a thermal solution that is significantly under designed may not be capable of cooling the processor even when the TCC is active continuously. See the appropriate processor Thermal Mechanical Design Guidelines for information on designing a compliant thermal solution. The Thermal Monitor does not require any additional hardware, software drivers, or interrupt handling routines. The following sections provide more details on the different TCC mechanisms used by the processor. Desktop 4th Generation Intel(R) CoreTM Processor Family, Desktop Intel(R) Pentium(R) Processor Family, and Desktop Intel(R) Celeron(R) Processor Family Datasheet - Volume 1 of 2 March 2015 78 Order No.: 328897-010 Thermal Management--Processor Frequency Control When the Digital Temperature Sensor (DTS) reaches a value of 0 (DTS temperatures reported using PECI may not equal zero when PROCHOT# is activated), the TCC will be activated and the PROCHOT# signal will be asserted if configured as bi-directional. This indicates the processor temperature has met or exceeded the factory calibrated trip temperature and it will take action to reduce the temperature. Upon activation of the TCC, the processor will stop the core clocks, reduce the core ratio multiplier by 1 ratio and restart the clocks. All processor activity stops during this frequency transition that occurs within 2 us. Once the clocks have been restarted at the new lower frequency, processor activity resumes while the core voltage is reduced by the internal voltage regulator. Running the processor at the lower frequency and voltage will reduce power consumption and should allow the processor to cool off. If after 1 ms the processor is still too hot (the temperature has not dropped below the TCC activation point, DTS still = 0 and PROCHOT is still active), then a second frequency and voltage transition will take place. This sequence of temperature checking and frequency and voltage reduction will continue until either the minimum frequency has been reached or the processor temperature has dropped below the TCC activation point. If the processor temperature remains above the TCC activation point even after the minimum frequency has been reached, then clock modulation (described below) at that minimum frequency will be initiated. There is no end user software or hardware mechanism to initiate this automated TCC activation behavior. A small amount of hysteresis has been included to prevent rapid active/inactive transitions of the TCC when the processor temperature is near the TCC activation temperature. Once the temperature has dropped below the trip temperature and the hysteresis timer has expired, the operating frequency and voltage transition back to the normal system operating point using the intermediate VID/frequency points. Transition of the VID code will occur first, to insure proper operation as the frequency is increased. Clock Modulation Clock modulation is a second method of thermal control available to the processor. Clock modulation is performed by rapidly turning the clocks off and on at a duty cycle that should reduce power dissipation by about 50% (typically a 30-50% duty cycle). Clocks often will not be off for more than 32 microseconds when the TCC is active. Cycle times are independent of processor frequency. The duty cycle for the TCC, when activated by the Thermal Monitor, is factory configured and cannot be modified. It is possible for software to initiate clock modulation with configurable duty cycles. A small amount of hysteresis has been included to prevent rapid active/inactive transitions of the TCC when the processor temperature is near its maximum operating temperature. Once the temperature has dropped below the maximum operating temperature and the hysteresis timer has expired, the TCC goes inactive and clock modulation ceases. Desktop 4th Generation Intel(R) CoreTM Processor Family, Desktop Intel(R) Pentium(R) Processor Family, and Desktop Intel(R) Celeron(R) Processor Family March 2015 Datasheet - Volume 1 of 2 Order No.: 328897-010 79 Processor--Thermal Management Immediate Transition to Combined TM1 and TM2 When the TCC is activated, the processor will sequentially step down the ratio multipliers and VIDs in an attempt to reduce the silicon temperature. If the temperature continues to increase and exceeds the TCC activation temperature by approximately 5 C before the lowest ratio/VID combination has been reached, the processor will immediately transition to the combined TM1/TM2 condition. The processor remains in this state until the temperature has dropped below the TCC activation point. Once below the TCC activation temperature, TM1 will be discontinued and TM2 will be exited by stepping up to the appropriate ratio/VID state. Critical Temperature Flag If TM2 is unable to reduce the processor temperature, then TM1 will be also be activated. TM1 and TM2 will then work together to reduce power dissipation and temperature. It is expected that only a catastrophic thermal solution failure would create a situation where both TM1 and TM2 are active. If TM1 and TM2 have both been active for greater than 20 ms and the processor temperature has not dropped below the TCC activation point, the Critical Temperature Flag in the IA32_THERM_STATUS MSR will be set. This flag is an indicator of a catastrophic thermal solution failure and that the processor cannot reduce its temperature. Unless immediate action is taken to resolve the failure, the processor will probably reach the Thermtrip temperature (see Testability Signals on page 91) within a short time. To prevent possible permanent silicon damage, Intel recommends removing power from the processor within 1/2 second of the Critical Temperature Flag being set. PROCHOT# Signal An external signal, PROCHOT# (processor hot), is asserted when the processor core temperature has exceeded its specification. If Adaptive Thermal Monitor is enabled (it must be enabled for the processor to be operating within specification), the TCC will be active when PROCHOT# is asserted. The processor can be configured to generate an interrupt upon the assertion or deassertion of PROCHOT#. By default, the PROCHOT# signal is set to bi-directional. However, it is recommended to configure the signal as an input only. When configured as an input or bi-directional signal, PROCHOT# can be used for thermally protecting other platform components should they overheat as well. When PROCHOT# is driven by an external device: * The package will immediately transition to the minimum operation points (voltage and frequency) supported by the processor and graphics cores. This is contrary to the internally-generated Adaptive Thermal Monitor response. * Clock modulation is not activated. The TCC will remain active until the system de-asserts PROCHOT#. The processor can be configured to generate an interrupt upon assertion and de-assertion of the PROCHOT# signal. Refer to the appropriate Platform Thermal Mechanical Design Guidelines (see Related Doucments section) for details on implementing the bidirectional PROCHOT# feature. Note: Toggling PROCHOT# more than once in 1.5 ms period will result in constant Pn state of the processor. Desktop 4th Generation Intel(R) CoreTM Processor Family, Desktop Intel(R) Pentium(R) Processor Family, and Desktop Intel(R) Celeron(R) Processor Family Datasheet - Volume 1 of 2 March 2015 80 Order No.: 328897-010 Thermal Management--Processor Note: A corner case exists for PROCHOT# configured as a bi-directional signal that can cause several milliseconds of delay to a system assertion of PROCHOT# when the output function is asserted. As an output, PROCHOT# (Processor Hot) will go active when the processor temperature monitoring sensor detects that one or more cores has reached its maximum safe operating temperature. This indicates that the processor Thermal Control Circuit (TCC) has been activated, if enabled. As an input, assertion of PROCHOT# by the system will activate the TCC for all cores. TCC activation when PROCHOT# is asserted by the system will result in the processor immediately transitioning to the minimum frequency and corresponding voltage (using Frequency control). Clock modulation is not activated in this case. The TCC will remain active until the system de-asserts PROCHOT#. Use of PROCHOT# in input or bi-directional mode can allow VR thermal designs to target maximum sustained current instead of maximum current. Systems should still provide proper cooling for the Voltage Regulator (VR), and rely on PROCHOT# only as a backup in case of system cooling failure. The system thermal design should allow the power delivery circuitry to operate within its temperature specification even while the processor is operating at its Thermal Design Power. 5.8 THERMTRIP# Signal Regardless of whether or not Adaptive Thermal Monitor is enabled, in the event of a catastrophic cooling failure, the processor will automatically shut down when the silicon has reached an elevated temperature (refer to the THERMTRIP# definition in Error and Thermal Protection Signals on page 92). THERMTRIP# activation is independent of processor activity. The temperature at which THERMTRIP# asserts is not user configurable and is not software visible. 5.9 Digital Thermal Sensor Each processor execution core has an on-die Digital Thermal Sensor (DTS) that detects the core's instantaneous temperature. The DTS is the preferred method of monitoring processor die temperature because: * It is located near the hottest portions of the die. * It can accurately track the die temperature and ensure that the Adaptive Thermal Monitor is not excessively activated. Temperature values from the DTS can be retrieved through: * A software interface using processor Model Specific Register (MSR). * A processor hardware interface as described in Platform Environmental Control Interface (PECI) on page 37. When temperature is retrieved by the processor MSR, it is the instantaneous temperature of the given core. When temperature is retrieved using PECI, it is the average of the highest DTS temperature in the package over a 256 ms time window. Intel recommends using the PECI reported temperature for platform thermal control that benefits from averaging, such as fan speed control. The average DTS temperature may not be a good indicator of package Adaptive Thermal Monitor activation or rapid increases in temperature that triggers the Out of Specification status bit within the PACKAGE_THERM_STATUS MSR 1B1h and IA32_THERM_STATUS MSR 19Ch. Desktop 4th Generation Intel(R) CoreTM Processor Family, Desktop Intel(R) Pentium(R) Processor Family, and Desktop Intel(R) Celeron(R) Processor Family March 2015 Datasheet - Volume 1 of 2 Order No.: 328897-010 81 Processor--Thermal Management Code execution is halted in C1 or deeper C-states. Package temperature can still be monitored through PECI in lower C-states. Unlike traditional thermal devices, the DTS outputs a temperature relative to the maximum supported operating temperature of the processor (TjMAX), regardless of TCC activation offset. It is the responsibility of software to convert the relative temperature to an absolute temperature. The absolute reference temperature is readable in the TEMPERATURE_TARGET MSR 1A2h. The temperature returned by the DTS is an implied negative integer indicating the relative offset from TjMAX. The DTS does not report temperatures greater than TjMAX. The DTS-relative temperature readout directly impacts the Adaptive Thermal Monitor trigger point. When a package DTS indicates that it has reached the TCC activation (a reading of 0h, except when the TCC activation offset is changed), the TCC will activate and indicate an Adaptive Thermal Monitor event. A TCC activation will lower both IA core and graphics core frequency, voltage, or both. Changes to the temperature can be detected using two programmable thresholds located in the processor thermal MSRs. These thresholds have the capability of generating interrupts using the core's local APIC. Refer to the Intel(R) 64 and IA-32 Architectures Software Developer's Manual for specific register and programming details. 5.9.1 Digital Thermal Sensor Accuracy (Taccuracy) The error associated with DTS measurements will not exceed 5 C within the entire operating range. 5.10 Intel(R) Turbo Boost Technology Thermal Considerations Intel Turbo Boost Technology allows processor cores and integrated graphics cores to run faster than the baseline frequency. During a turbo event, the processor can exceed its TDP power for brief periods. Turbo is invoked opportunistically and automatically as long as the processor is conforming to its temperature, power delivery, and current specification limits. Thus, thermal solutions and platform cooling that are designed to less than thermal design guidance may experience thermal and performance issues since more applications will tend to run at or near the maximum power limit for significant periods of time. 5.10.1 Intel(R) Turbo Boost Technology Power Control and Reporting Package processor core and internal graphics core powers are self monitored and correspondingly reported out. * With the processor turbo disabled, rolling average power over 5 seconds will not exceed the TDP rating of the part for typical applications. * With turbo enabled (see Figure 22 on page 84) -- For the PL1: Package rolling average of the power set in POWER_LIMIT_1 (TURBO_POWER_LIMIT MSR 0610h bits [14:0]) over time window set in POWER_LIMIT_1_TIME (TURBO_POWER_LIMIT MSR 0610h bits [23:17]) must be less than or equal to the TDP package power as read from the PACKAGE_POWER_SKU MSR 0614h for typical applications. Power control is valid only when the processor is operating in turbo. PL1 lower than the package TDP is not guaranteed. -- For the PL2: Package power will be controlled to a value set in POWER_LIMIT_2 (TURBO_POWER_LIMIT MSR 0610h bits [46:32]). Occasional brief power excursions may occur for periods of less than 10 ms over PL2.

This also assumes the processor is working within other product specifications. * Setting power limits (PL1 or PL2) below TDP are not ensured to be followed, and are not characterized for accuracy. * Under unknown work loads and unforeseen applications the average processor power may exceed Power Limit 1 (PL1). * Uncharacterized workloads may exist that could result in higher turbo frequencies and power. If that were to happen, the processor Thermal Control Circuitry (TCC) would protect the processor. The TCC protection must be enabled by the platform for the product to be within specification. An illustration of Intel Turbo Boost Technology power control is shown in the following sections and figures. Multiple controls operate simultaneously allowing for customization for multiple system thermal and power limitations. These controls provide turbo optimizations within system constraints. 5.10.2 Package Power Control The package power control allows for customization to implement optimal turbo within platform power delivery and package thermal solution limitations.

Intel(R) Turbo Boost Technology 2.0 Package Power Control Settings MSR: Address: MSR_TURBO_POWER_LIMIT 610h Control Bit Default Description * * POWER_LIMIT_1 (PL1) 14:0 SKU TDP * POWER_LIMIT_1_TIME (Turbo Time Parameter) POWER_LIMIT_2 (PL2) 23:17 46:32 This value sets the average power limit over a long time period. This is normally aligned to the TDP of the part and steady-state cooling capability of the thermal solution. The default value is the TDP for the SKU. PL1 limit may be set lower than TDP in real time for specific needs, such as responding to a thermal event. If it is set lower than TDP, the processor may require to use frequencies below the guaranteed P1 frequency to control the low-power limits. The PL1 Clamp bit [16] should be set to enable the processor to use frequencies below P1 to control the setpower limit. PL1 limit may be set higher than TDP. If set higher than TDP, the processor could stay at that power level continuously and cooling solution improvements may be required. 1 sec This value is a time parameter that adjusts the algorithm behavior to maintain time averaged power at or below PL1. The hardware default value is 1 second; however, 28 seconds is recommended for most mobile applications. 1.25 x TDP PL2 establishes the upper power limit of turbo operation above TDP, primarily for platform power supply considerations. Power may exceed this limit for up to 10 ms. The default for this limit is 1.25 x TDP; however, the BIOS may reprogram the default value to maximize the performance within platform power supply considerations. Setting this limit to TDP will limit the processor to only operate up to the TDP. It does not disable turbo because turbo is opportunistic and power/temperature dependent. Many workloads will allow some turbo frequencies for powers at or below TDP. Figure 22. Package Power Control 5.10.3 Turbo Time Parameter Turbo Time Parameter is a mathematical parameter (units in seconds) that controls the Intel Turbo Boost Technology algorithm using an average of energy usage. During a maximum power turbo event of about 1.25 x TDP, the processor could sustain Power_Limit_2 for up to approximately 1.5 the Turbo Time Parameter.

Due to this integration, the processor has one main voltage rail (VCC) and a voltage rail for the memory interface (VDDQ) , compared to six voltage rails on previous processors. The VCC voltage rail will supply the integrated voltage regulators which in turn will regulate to the appropriate voltages for the cores, cache, system agent, and graphics. This integration allows the processor to better control on-die voltages to optimize between performance and power savings. The processor VCC rail will remain a VID-based voltage with a loadline similar to the core voltage rail (also called VCC) in previous processors. 7.2 Power and Ground Lands The processor has VCC, VDDQ, and VSS (ground) lands for on-chip power distribution. All power lands must be connected to their respective processor power planes; all VSS lands must be connected to the system ground plane. Use of multiple power and ground planes is recommended to reduce I*R drop. The VCC lands must be supplied with the voltage determined by the processor Serial Voltage IDentification (SVID) interface. Table 46 on page 95 specifies the voltage level for the various VIDs. 7.3 VCC Voltage Identification (VID) The processor uses three signals for the serial voltage identification interface to support automatic selection of voltages. The following table specifies the voltage level corresponding to the 8-bit VID value transmitted over serial VID. A `1' in this table refers to a high voltage level and a `0' refers to a low voltage level. If the voltage regulation circuit cannot supply the voltage that is requested, the voltage regulator must disable itself. VID signals are CMOS push/pull drivers. See the Voltage and Current Specifications section for the DC specifications for these signals. The VID codes will change due to temperature and/or current load changes to minimize the power of the part. A voltage range is provided in the Voltage and Current Specifications section. The specifications are set so that one voltage regulator can operate with all supported frequencies. Individual processor VID values may be set during manufacturing so that two devices at the same core frequency may have different default VID settings. This is shown in the VID range values in the Voltage and Current Specifications section. The processor provides the ability to operate while transitioning to an adjacent VID and its associated voltage. This will represent a DC shift in the loadline.

Desktop 4th Generation Intel(R) CoreTM Processor Family, Desktop Intel(R) Pentium(R) Processor Family, and Desktop Intel(R) Celeron(R) Processor Family Datasheet - Volume 1 of 2 March 2015 98 Order No.: 328897-010 Electrical Specifications--Processor 7.4 Reserved or Unused Signals The following are the general types of reserved (RSVD) signals and connection guidelines: * RSVD - these signals should not be connected * RSVD_TP - these signals should be routed to a test point * RSVD_NCTF - these signals are non-critical to function and may be left unconnected Arbitrary connection of these signals to VCC, VDDQ, VSS, or to any other signal (including each other) may result in component malfunction or incompatibility with future processors. See Signal Description on page 86 for a pin listing of the processor and the location of all reserved signals. For reliable operation, always connect unused inputs or bi-directional signals to an appropriate signal level. Unused active high inputs should be connected through a resistor to ground (VSS). Unused outputs maybe left unconnected; however, this may interfere with some Test Access Port (TAP) functions, complicate debug probing, and prevent boundary scan testing. A resistor must be used when tying bi-directional signals to power or ground. When tying any signal to power or ground, a resistor will also allow for system testability. 7.5 Signal Groups Signals are grouped by buffer type and similar characteristics as listed in the following table. The buffer type indicates which signaling technology and specifications apply to the signals. All the differential signals and selected DDR3/DDR3L and Control Sideband signals have On-Die Termination (ODT) resistors. Some signals do not have ODT and need to be terminated on the board. Note: All Control Sideband Asynchronous signals are required to be asserted/de-asserted for at least 10 BCLKs with maximum Trise/Tfall of 6 ns for the processor to recognize the proper signal state.

SA and SB refer to DDR3/DDR3L Channel A and DDR3/DDR3L Channel B. 7.6 Test Access Port (TAP) Connection Due to the voltage levels supported by other components in the Test Access Port (TAP) logic, Intel recommends the processor be first in the TAP chain, followed by any other components within the system. A translation buffer should be used to connect to the rest of the chain unless one of the other components is capable of accepting an input of the appropriate voltage. Two copies of each signal may be required with each driving a different voltage level. The processor supports Boundary Scan (JTAG) IEEE 1149.1-2001 and IEEE 1149.6-2003 standards. A few of the I/O pins may support only one of those standards. 7.7 DC Specifications The processor DC specifications in this section are defined at the processor pins, unless noted otherwise. See Signal Description on page 86 for the processor pin listings and signal definitions. * The DC specifications for the DDR3 / DDR3L signals are listed in the Voltage and Current Specifications section. * The Voltage and Current Specifications section lists the DC specifications for the processor and are valid only while meeting specifications for junction temperature, clock frequency, and input voltages.

Unless otherwise noted, all specifications in this table are based on estimates and simulations or empirical data. 2. Each processor is programmed with a maximum valid voltage identification value (VID) that is set at manufacturing and cannot be altered. Individual maximum VID values are calibrated during manufacturing such that two processors at the same frequency may have different settings within the VID range. This differs from the VID employed by the processor during a power management event (Adaptive Thermal Monitor, Enhanced Intel SpeedStep Technology, or Low-Power States). 3. The voltage specification requirements are measured across VCC_SENSE and VSS_SENSE lands at the socket with a 20-MHz bandwidth oscilloscope, 1.5 pF maximum probe capacitance, and 1M minimum impedance. The maximum length of ground wire on the probe should be less than 5 mm. Ensure external noise from the system is not coupled into the oscilloscope probe. 4. ICC_MAX specification is based on the VCC loadline at worst case (highest) tolerance and ripple. 5. The VCC specifications represent static and transient limits. 6. The loadlines specify voltage limits at the die measured at the VCC_SENSE and VSS_SENSE lands. Voltage regulation feedback for voltage regulator circuits must also be taken from processor VCC_SENSE and VSS_SENSE lands. 7. PSx refers to the voltage regulator power state as set by the SVID protocol. 8. PCG is Platform Compatibility Guide (previously known as FMB). These guidelines are for estimation purposes only. 9. PMAX is the maximum power the processor will dissipate as measured at VCC_SENSE and VSS_SENSE lands. The processor may draw this power for up to 10 ms before it regulates to PL2. Table 49.
