2 Electrical Specifications

2.1 Intel® QPI Differential Signaling

The processor provides an Intel QPI port for high speed serial transfer between other Intel QPI-enabled components. The Intel QPI port consists of two unidirectional links (for transmit and receive). Intel QPI uses a differential signalling scheme where pairs of opposite-polarity (D_P, D_N) signals are used.

On-die termination (ODT) is provided on the processor silicon and termination is to V Intel chipsets also provide ODT; thus, eliminating the need to terminate the Intel QPI links on the system board.

Intel strongly recommends performing analog simulations of the Intel

Figure 2-1 illustrates the active ODT. Signal listings are included in Table 2-3 and Table 2-4. See Chapter 5 for the pin signal definitions. All Intel QPI signals are in the

differential signal group.

Figure 2-1. Active ODT for a Differential Link Example

2.2 Power and Ground Lands

For clean on-chip processor core power distribution, the processor has 210 VCC pads and 119 VSS pads associated with V

; 28 VTTD pads and 17 VSS pads associated with V

; and 3 VCCPLL pads. All VCCP, VTTA, VTTD, VDDQ and

DDQ

VCCPLL lands must be connected to their respective processor power planes, while all VSS lands must be connected to the system ground plane. The processor VCC lands must be supplied with the voltage determined by the processor Voltage IDentification (VID) signals. Table 2-1 specifies the voltage level for the various VIDs.

TTD

2.3 Decoupling Guidelines

Due to its large number of transistors and high internal clock speeds, the processor is capable of generating large current swings between low and full power states. This may cause voltages on power planes to sag below their minimum values if bulk decoupling is not adequate. Larger bulk storage (C current during longer lasting changes in current demand; such as, coming out of an idle condition. Similarly, capacitors act as a storage well for current when entering an idle condition from a running condition. Care must be taken in the baseboard design to

), such as electrolytic capacitors, supply

Electrical Specifications

ensure that the voltage provided to the processor remains within the specifications listed in Table 2-7. Failure to do so can result in timing violations or reduced lifetime of the processor.

2.3.1 VCC, V

Voltage regulator solutions need to provide bulk capacitance and the baseb o ard designer must assure a low interconnect resistance from the regulator to the LGA1366 socket. Bulk decoupling must be provided on the baseboard to handle large current swings. The power delivery solution must insure the voltage and current specifications are met (as defined in Table 2-7).

2.4 Processor Clocking (BCLK_DP, BCLK_DN)

The processor core, Intel QPI, and integrated memory controller frequencies are generated from BCLK_DP and BCLK_DN. Unlike previous processors based on front side bus architecture, there is no direct link between core frequency and Intel QPI link frequency (such as, no core frequency to Intel QPI multiplier). The processor maximum core frequency, Intel QPI link frequency and integrated memory controller frequency, are set during manufacturing. It is possible to override the processor core frequency setting using software. This permits operation at lower core frequencies than the factory set maximum core frequency.

The processor’s maximum non-turbo core frequency is configured during power-on reset by using values stored internally during manufacturing. The stored value sets the highest core multiplier at which the particular processor can operate. If lower max nonturbo speeds are desired, the appropriate ratio can be configured using the CLOCK_FLEX_MAX MSR.

The processor uses differential clocks (B CLK_DP, BCLK_DN). Clock multiplying within the processor is provided by the internal phase locked loop (PLL), which requires a constant frequency BCLK_DP, BCLK_DN input, with exceptions for spread spectrum clocking. The processor core frequency is determined by multiplying the ratio by 133 MHz.

2.4.1 PLL Power Supply

An on-die PLL filter solution is implemented on the processor. Refer to Table 2-7 for DC specifications.

2.5 Voltage Identification (VID)

The voltage set by the VID signals is the reference voltage regulator output voltage to be delivered to the processor VCC pins. VID signals are CMOS push/pull drivers. Refer to Table 2-15 for the DC specifications for these signals. The VID codes will change due to temperature and/or current load changes in order to minimize the power of the part. A voltage range is provided in Table 2-7. The specifications have been set such that one voltage regulator can operate with all supported frequencies.

Individual processor VID values may be set during manufacturing such that two devices at the same core frequency may have different default VID settings. This is reflected by the VID range values provided in Table 2-1.

14 Datasheet

Electrical Specifications

The processor uses eight voltage identification signals, VID[7:0], to support automatic selection of voltages. Table 2-1 specifies the voltage level corresponding to the state of VID[7:0]. A ‘1’ in this table refers to a high voltage level and a ‘0’ refers to a low voltage level. If the processor socket is empty (VID[7:0] = 11111111), or the voltage regulation circuit cannot supply the voltage that is requested, the voltage regulator must disable itself.

The processor its associated processor core voltage (V

provides the ability to operate while transitioning to an adjacent VID and

). This will represent a DC shift in the

loadline. It should be noted that a low-to-high or high-to-low voltage state change will result in as many VID transitions as necessary to reach the target core voltage. T ransitions abo ve the maximum specified VID are not permitted. Table 2-8 includes VID step sizes and DC shift ranges. Minimum and maximum voltages must be maintained as shown in Ta ble 2-8.

The VR used must be capable of regulating its output to the value defined by the new VID. DC specifications for dynamic VID transitions are included in Table 2-7 and

For reliable operation, always connect unused inputs or bi-directional signals to an appropriate signal level, except for unused integrated memory controller inputs, outputs, and bi-directional pins which may be left floating. Unused active high inputs should be connected through a resistor to ground (V 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.

All Control Sideband Asynchronous signals are required to be asserted/de-asserted for at least eight BCLKs for the processor to recognize the proper signal state. See

Section 2.11 for the DC specifications. See Chapter 6 for additional timing

requirements for entering and leaving the low power states.

2.8 Test Access Port (TAP) Connection

Due to the voltage levels supported by other components in the Test Access Port (TAP) logic, it is recommended that the processor be first in the TAP chain and 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.

2.9 Platform Environmental Control Interface (PECI) DC Specifications

PECI is an Intel proprietary interface that provides a communication channel between Intel processors and chipset components to external thermal monitoring devices. The processor contains a Digital Thermal Sensor (DTS) that reports a relative die temperature as an offset from Thermal Control Circuit (TCC) activation temperature. Temperature sensors located throughout the die are implemented as analog-to-digital converters calibrated at the factory. PECI provides an interface for external devices to read the DTS temperature for thermal management and fan speed control. More detailed information may be found in the Platform Environment Control Interface

(PECI) Specification.

2.9.1 DC Characteristics

The PECI interface operates at a nominal voltage set by V specifications shown in Table 2-5 is used with devices normally operating from a V interface supply. V

nominal levels will vary between processor families. All PECI

devices will operate at the V system. For specific nominal V

2.10 Absolute Maximum and Minimum Ratings

Table 2-6 specifies absolute maximum and minimum ratings, which lie outside the

functional limits of the processor. Only within specified operation limits can functionality and long-term reliability be expected.

At conditions outside functional operation condition limits, but within absolute maximum and minimum ratings, neither functionality nor long-term reliability can be expected. If a device is returned to conditions within functional operation limits after having been subjected to conditions outside these limits, but within the absolute maximum and minimum ratings, the device may be functional, but with its lifetime degraded depending on exposure to conditions exceeding the functional operation condition limits.

At conditions exceeding absolute maximum and minimum ratings, neither functionality nor long-term reliability can be expected. Moreover, if a device is subjected to these conditions for any length of time then, when returned to conditions within the functional operating condition limits, it will either not function or its reliability will be severely degraded.

Although the processor contains protective circuitry to resist damage from ElectroStatic Discharge (ESD), precautions should always be taken to avoid high static voltages or electric fields.

2. Each processor is programmed with a maximum valid voltage identification value (VID), which is set at manufacturing and can not 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. Please note this differs from the VID employed by the processor during a power management event (Adaptive Thermal Monitor, Enhanced Intel SpeedStep

3. The voltage specification requirements are measured across VCC_SENSE and VSS_SENSE la nds at the socket with a 100 MHz bandwidth oscilloscope, 1.5 pF maximum probe capacitance, and 1 M 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. Refer to Table 2-8

The processor should not be subjected to any VCC and ICC combination wherein VCC exceeds V a given current.

3 Package Mechanical

Specifications

The processor is packaged in a Flip-Chip Land Grid Array package that interfaces with the motherboard using an LGA1366 socket. The package consists of a processor mounted on a substrate land-carrier. An integrated heat spreader (IHS) is attached to the package substrate and core and serves as the mating surface for processor thermal solutions, such as a heatsink. Figure 3-1 shows a sketch of the processor package components and how they are assembled together. Refer to the appropriate processor Thermal and Mechanical Design Guidelines (see Section 1.2) for complete details on the LGA1366 socket.

The package components shown in Figure 3-1 include the following:

• Integrated Heat Spreader (IHS)

• Thermal Interface Material (TIM)

• Processor core (die)

• Package substrate

• Capacitors

Figure 3-1. Processor Package Assembly Sketch

Note:

1. Socket and motherboard are included for reference and are not part of the processor package.

3.1 Package Mechanical Drawing

The package mechanical drawings are shown in Figure 3-2 and Figure 3-3. The drawings include dimensions necessary to design a thermal solution for the processor. These dimensions include:

• Package reference with tolerances (total height, length, width, etc.)

• IHS parallelism and tilt

• Land dimensions

• Top-side and back-side component keep-out dimensions

• Reference datums

• All drawing dimensions are in mm.

• Guidelines on potential IHS flatness variation with socket load plate actuation and installation of the cooling solution is available in the appropriate processor Thermal and Mechanical Design Guidelines (see Section 1.2).

3.2 Processor Component Keep-Out Zones

The processor may contain components on the substrate that define component keepout zone requirements. A thermal and mechanical solution design must not intrude into the required keep-out zones. Decoupling capacitors are typically mounted to either the top-side or land-side of the package substrate. See Figure 3-2 and Figure 3-3 for keepout zones. The location and quantity of package capacitors may change due to manufacturing efficiencies but will remain within the component keep-in.

3.3 Package Loading Specifications

Table 3-1 provides dynamic and static load specifications for the processor package.

These mechanical maximum load limits should not be exceeded during heatsink assembly, shipping conditions, or standard use condition. Also, any mechanical system or component testing should not exceed the maximum limits. The processor package substrate should not be used as a mechanical reference or load-bearing surface for

Table 3-1. Processor Loading Specifications

Notes:

1. These specifications apply to uniform compressive loading in a direction normal to the processor IHS.

2. This is the minimum and maximum static force that can be applied by the heatsink and retention solution to maintain the heatsink and processor interface.

3. These specifications are based on limited testing for design characterization. Loading limits are for the package only and do not include the limits of the processor socket.

4. Dynamic loading is defined as an 11 ms duration average load superimposed on the static load requirement.

3.4 Package Handling Guidelines

Table 3-2 includes a list of guidelines on package handling in terms of recommended

maximum loading on the processor IHS relative to a fixed substrate. These package handling loads may be experienced during heatsink removal.

BPM#[7:0] are breakpoint and performance monitor signals. They are outputs from the processor that indicate the status of breakpoints and programmable counters used for monitoring processor performance. BPM#[7:0] should be connected in a wired OR topology between all packages on a platfor m. The e nd points for the wired OR connections must be terminated.

CAT_ERR# indicates that the system has experienced a catastrophic error and cannot continue to operate. The processor will set this for non-recoverable machine check errors and other internal unrecoverable error. Since this is an I/ O pin, external agents are allowed to assert this pin which will cause the processor to take a machine check exception.

Impedance compensation must be terminated on the system board using a precision resistor.

Intel QPI received clock is the input clock that corresp onds to the receiv ed d ata.

Intel QPI forwarded clock sent with the outbound data.

QPI_DRX_DN[19:0] and QPI_DRX_DP[19:0] comprise the differential receive

PECI (Platform Environment Control Interface) is the serial sideband interface to the processor and is used primarily for ther mal, power and error management. Details regarding the PECI electrical specifications, protocols and functions can be found in the Platform Environment Control Interface Specification.

PRDY# is a processor output used by debug tools to dete rmine processor de bug readiness.

PROCHOT# will go active when the processor temperature monitoring sensor detects that the processor has reached its ma ximum safe operating temperature. This indicates that the processor Thermal Control Circuit has been activated, if enabled. This signal can also be driven to the processor to activate the Thermal Control Circuit. This signal does not have on-die termination and must be terminated on the system board.

Processor Power Status Indicator signal. This signal is asserted when maximum possible processor core current consumption is less than 20A. Assertion of this signal is an indication that the VR controller does not currently need to be able to provide ICC above 20A, and the VR controller can use this information to move to more efficient operation point. This signal will de-assert at least 3.3 us before the current consumption will exceed 20A. The minimum PSI# assertion and de-assertion time is 1 BCLK.

Asserting the RESET# signal resets the processor to a known state and invalidates its internal caches without writing back any of their contents. Note some PLL, QPI and error states are not effected by reset and only VCCPWRGOOD forces them to a known state. For a power-on Reset, RESET# must stay active for at least one millisecond after VCC and BCLK have reached their proper specifications. RESET# must not be kept asserted for more than 10 ms while VCCPWRGOOD is asserted. RESET# must be held de-asserted for at least 1 ms before it is asserted again. RESET# must be held asserted before VCCPWRGOOD is asserted. This signal does not have on-die termination and must be terminated on the system board. RESET# is a common clock signal.

SKTOCC# (Socket Occupied) will be pulled to ground on the processor package. There is no connection to the processor silicon for this signal. System board designers may use this signal to determine if the processor is present.

TCK (T est Clock) provides the clock input for the processor Test Bus (also known as the Test Access Port).

TDI (T est D ata In) tr ansfers serial test data into the processor. TDI provides the serial input needed for JTAG specification support.

TDO (Test Data Out) transfers serial test data out of the processor. TDO provides the serial output needed for JTAG specification support.

TESTLOW must be connected to ground thro ugh a resistor for proper processor operation.

VCCPWRGOOD (Power Good) is a processor input. The processor requires this signal to be a clean indication that BCLK, V are stable and within their specifications. 'Clean' implies that the signal will remain low (capable of sinking leakage current), without glitches, from the time that the power supplies are turned on until they come within specification. The signal must then transition monotonically to a high state. VCCPWRGO OD can be driven inactive at any time, but BCLK and power must again be stable before a subsequent rising edge of VCCPWRGOOD. In addition at the time VCCPWRGOOD is asserted RESET# must be active. The PWRGOOD signal must be supplied to the processor. It should be driven high throughout boundary scan operation.

VDDPWRGOOD is an input that indicates the V processor requires this signal to be a clean indication that the V supply is stable and within specifications. "Clean" implies that the signal will remain low (capable of sinking leakage current), without glitches, from the time that the Vddq supply is turned on until it comes within specification. The signals must then transition monotonically to a high state.

The PwrGood signal must be supplied to the processor. VID[7:0] (Voltage ID) are used to support automatic selection of power supply

Thermal Specifications

6 Thermal Specifications

6.1 Package Thermal Specifications

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).

This chapter provides data necessary for developing a complete thermal solution. For more information on designing a component level thermal solution, refer to the appropriate processor Thermal and Mechanical Design Guidelines (see Section 1.2).

6.1.1 Thermal Specifications

The processor thermal specification uses the on-die Digital Thermal Sensor (DTS) value reported using the PECI interface for all processor temperature measurements. The DTS is a factory calibrated, analog to digital thermal sensor. As a result, it will no longer be necessary to measure the processors case temperature. Consequently , there will be no need for a Thermal Profile specification defining the relationship between the processors T

Note: Unless otherwise specified, the term “DTS” refers to the DTS value returned by the

PECI interface gettemp command.

Note: A thermal solution that was verified compliant to the processor case temperature

thermal profile at the customer defined boundary conditions is expected to be compliant with this update. No redesign of the thermal solution should be necessary. A fan speed control algorithms that was compliant to the previous thermal requirements is also expected to be compliant with this specification. The fan speed control algorithm can be updated to use the additional information to optimize acoustics.

To allow the optimal operation and long-term reliability of Intel processor-based systems, the processor thermal solution must deliver the specified thermal solution performance in response to the DTS sensor value. The thermal solution performance will be measured using a Thermal Test Vehicle (TTV). See Table 6-1 and Figure 6-1 for the TTV thermal profile and Table 6-3 for the required thermal solution performance table when DTS values are greater than T provide this level of thermal capability may affect the long-term reliability of the processor and system. When the DTS value is less than T performance is not defined and the fans may be slowed down. This is unchanged from the prior specification. For more details on thermal solution design, refer to the appropriate processor Thermal and Mechanical Design Guidelines (see Section 1.2).

The processors implement a methodology for managing processor temperatures, which 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

Datasheet 71

Thermal Specifications

in Section 6.3. 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 Section 6.2, Processor Thermal Features). 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 thermal solution provides the 

that

meets the TTV thermal profile specifications. A single integer change in the PECI value corresponds to approximately 1 °C change in

processor temperature. Although each processors DTS is factory calibrated, the accuracy of the DTS will vary from part to part and may also vary slightly with temperature and voltage. In general, each integer change in PECI should equal a temperature change between 0.9 °C and 1.1 °C.

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, refer to

Section 6.2. Refer to the appropriate processor Thermal and Mechanical Design Guide

(see Section 1.2) for details on system thermal solution design, thermal profiles and environmental considerations.

6.2 Processor Thermal Features

6.2.1 Processor Temperature

A new feature in the Intel Core™ i7-900 desktop processor Extreme Edition series and Intel Core™ i7-900 desktop processor series is a software readable field in the IA32_TEMPERATURE_TARGET register that 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.

Note: There is no specified correlation between DTS temperatures and processor case

temperatures; therefore it is not possible to use this feature to ensure the processor case temperature meets the Thermal Profile specifications.

6.2.2 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 Th erm al Monitor uses T CC activation to reduce processor power using a combination of methods. The first method (Frequency/VID control, similar to Thermal Monitor 2 (TM2) in previous generation processors) involves the processor reducing its operating frequency (using the core ratio multiplier) and input voltage (using the VID signals). This combination of lower frequency and VID results in a reduction of the processor power consumption. The second method (clock modulation, known as Thermal Monitor 1 (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 then 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 would 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 under-designed 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 T 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 . Refer to the appropriate processor Thermal and Mechanical Design Guide (see Section 1.2) 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 Intel Core™ i7-900 desktop processor Extreme Edition series and Intel Core™ i7-900 desktop processor series.

6.2.2.1 Frequency/VID 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, see Section 6.3 for further details), the TCC will be activated and the PROCHOT# signal will be asserted. 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, which occurs within 2 us. Once the clocks have been restarted at the new lower frequency , processor activity resumes while the voltage requested by the VID lines is stepped down to the minimum possible for the particular frequency. 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/VID 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. T r ansition of the VID code will occur first, to insure proper oper ation as the frequency is increased. Refer to Table 6-3 for an illustration of this ordering.

Figure 6-3. Frequency and Voltage Ordering

Datasheet 77

6.2.2.2 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 µs 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.

6.2.2.3 Immediate Transiton to combined TM1 and TM2

As mentioned above, 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, then the processor will immediately transition to the combined TM1/TM2 condition. The processor will remain 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.

Thermal Specifications

6.2.2.4 Critical Temperature Fla g

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, then 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 Section 6.2.3 Thermtrip Signal) within a short time. To prevent possible permanent silicon damage, Intel recommends removing power from the processor within ½ second of the Critical Te mperature Flag being set.

6.2.2.5 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 (note 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#.

Although the PROCHOT# signal is an output by default, it may be configured as bidirectional. When configured in bi-directional mode, it is either an output indicating the processor has exceeded its TCC activation temperature or it can be driven from an

78 Datasheet

Thermal Specifications

external source (e.g., a voltage regulator) to activate the TCC. The ability to activate the TCC using PROCHOT# can provide a means for thermal protection of system components.

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 Freq/VID control). Clock modulation is not activated in this case. The TCC will remain active until the system de-asserts PROCHOT#.

Use of PROCHOT# in 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 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.

6.2.3 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

Table 5-1). THERMTRIP# activation is independent of processor activity. The

6.3 Platform Environment Control Interface (PECI)

6.3.1 Introduction

The Platform Environment Control Interface (PECI) is a one-wire interface that provides a communication channel between the Intel processor and chipset components to external monitoring devices. The processor implements a PECI interface to allow communication of processor thermal and other information to other devices on the platform. The processor provides a digital thermal sensor (DTS) for fan speed control. The DTS is calibrated at the factory to provide a digital representation of relative processor temperature. Instantaneous temperature readings from the DTS are available using the IA32_THERM_STATUS MSR; averaged DTS values are read using the PECI interface.

The PECI physical layer is a self-clocked one-wire bus that begins each bit with a driven, rising edge from an idle level near zero volts. The duration of the signal driven high depends on whether the bit value is a logic '0' or logic '1'. PECI also includes variable data transfer rate established with every message. The single wire interface provides low board routing overhead for the multiple load connections in the congested routing area near the processor and chipset components. Bus speed, error checking, and low protocol overhead provides adequate link bandwidth and reliability to transfer critical device operating conditions and configuration information.

always a negative value and represents a delta below the onset of thermal control circuit (TCC) activation, as indicated by PROCHOT#. Therefore, as the temperature approaches TCC activation, the value approaches zero degrees.

6.3.1.2 Processor Thermal Data Sample Rate and Filtering

The processor digital thermal sensor (DTS) provides an improved capability to monitor device hot spots, which inherently leads to more varying temperature readings over short time intervals. To reduce the sample rate requirements on PECI and improve thermal data stability versus. time the processor DTS implements an averaging algorithm that filters the incoming data. This filter is expressed mathematically as:

PECI(t) = PECI(t–1)+1/(2^^X)*[Temp – PECI(t–1)]

Where: PECI(t) is the new averaged temperature; PECI(t-1) is the previous averaged temperature; Temp is the raw temperature data from the DTS; X is the Thermal Averaging Constant (TAC)

Note: Only values read using the PECI interface are averaged. Temperature values read using

the IA32_THERM_STATUS MSR are not averaged. The Thermal Averaging Constant is a BIOS configurable value that determines the time

in milliseconds over which the DTS temperature values are averaged. Short averaging times will make the averaged temperature values respond more quickly to DTS changes. Long averaging times will result in better overall thermal smoothing but also incur a larger time lag between fast DST temperature changes and the value read using PECI. Refer to the appropriate processor Thermal and Mechanical Design Guidelines (see Section 1.2) for further details on the Data Filter and the Thermal Averaging Constant.

Within the processor, the DTS converts an analog signal into a digital value representing the temperature relative to TCC activation. The conversions are in integers with each single number change corresponding to approximately 1 °C. DTS values reported using the internal processor MSR will be in whole integers.

As a result of the averaging function described above, DTS values reported over PECI will include a 6-bit fractional value. Under typical operating conditions, where the temperature is close to T the temperature approaches zero, the fractional values can be used to detect the

CONTROL

, the fractional values may not be of interest. But when

activation of the TCC. An averaged temperature value between 0 and 1 can only occur if the TCC has been activated during the averaging window. As TCC activation time increases, the fractional value will approach zero. Fan control circuits can detect this situation and take appropriate action as determined by the system designers. Of course, fan control chips can also monitor the PROCHOT# pin to detect TCC activation using a dedicated input pin on the package. Further details on how the Thermal Averaging Constant influences the fractional temperature values are available in the Thermal Design Guide.

6.3.2.3 PECI Fault Handling Requirements

PECI is largely a fault tolerant interface, including noise immunity and error checking improvements over other comparable industry standard interfaces. The PECI client is as reliable as the device that it is embedded in, and thus given operating conditions that fall under the specification. The PECI will always respond to requests and the protocol itself can be relied upon to detect any transmission failures. There are, however, certain scenarios where the PECI is know to be unresponsive. Prior to a power on RESET# and during RESET# assertion, PECI is not ensured to provide reliable thermal data. System designs should implement a default power-on condition that ensures proper processor operation during the time frame when reliable data is not available using PECI.

To protect platforms from potential operational or safety issues due to an abnormal condition on PECI, the Host controller should take action to protect the system from possible damaging states. If the Host controller cannot complete a valid PECI transactions of GetTemp0() with a given PECI device over 3 consecutive failed transactions or a one second maximum specified interval, then it should take appropriate actions to protect the corresponding device and/or other system components from overheating. The host controller may also implement an alert to software in the event of a critical or continuous fault condition.

7.2 Clock Control and Low Power States

The processor supports low power states at the individual thread, core, and package level for optimal power management. The processor implements software interfaces for requesting low power states: MWAIT instruction extensions with sub-state hints, the HLT instruction (for C1 and C1E) and P_LVLx reads to the ACPI P_BLK register block mapped in the processor’s I/O address space. The P_LVLx I/O reads are converted to equivalent MWAIT C-state requests inside the processor and do not directly result in I/O reads to the system. The P_LVLx I/O Monitor address does not need to be set up before using the P_LVLx I/O read interface.

Software may make C-state requests by using a legacy method involving I/O reads from the ACPI-defined processor clock control registers, referred to as P_LVLx. This feature is designed to provide legacy support for operating systems that initiate C-state transitions using access to pre-defined ICH registers. The base P_LVLx register is P_LVL2, corresponding to a C3 request; P_LVL3 is C6.

P_LVLx is limited to a subset of C-states. F or Example, P_LVL8 is not supported and will not cause an I/O redirection to a C8 request. Instead, it will fall through like a normal I/O instruction. The range of I/O addresses that may be converted into C-state requests is also defined in the PMG_IO_CAPTURE MSR, in the ‘C-state Range’ field. This field maybe written by BIOS to restrict the range of I/O addresses that are trapped an d redirected to MWAIT instructions. Note that when I/O instructions are used, no MWAIT substates can be defined, as therefore the request defaults to have a sub-state or zero, but always assumes the ‘break on IF==0’ control that can be selected using ECX with an MWAIT instruction.

RESET# will cause the processor to initialize itself.

Features

While in C1/C1E state, the processor will process bus snoops and snoops from the other threads.

7.2.1.3 C3 State

Individual threads of the processor can enter the C3 state by initiating a P_LVL2 I/O read to the P_BLK or an MWAIT(C3) instruction. Before entering core C3, the processor flushes the contents of its caches. Except for the caches, the processor core maintains all its architectural state while in the C3 state. All of the clocks in the processor core are stopped in the C3 state.

Because the core’s caches are flushed, the processor keeps the core in the C3 state when the processor detects a snoop on the Intel QPI Link or when another logical processor in the same package accesses cacheable memory. The processor core will transition to the C0 state upon occurrence of an interrupt. RESET# will cause the processor core to initialize itself.

7.2.1.4 C6 State

Individual threads of the processor can enter the C6 state by initiating a P_LVL3 read to the P_BLK or an MWAIT(C6) instruction. Before entering Core C6, the processor saves core state data (such as, registers) to the last level cache. This data is retired after exiting core C6. The processor achieves additional power savings in the core C6 state.

7.2.2 Package Power State Descriptions

The package supports C0, C3, and C6 power states. Note that there is no package C1 state. The package power state is automatically resolved by the processor depending on the core power states and permission from the rest of the system as described in the following sections.

7.2.2.1 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 another component in the system has not granted permission to the processor to go into a low power state. Individual components of the processor may be in low power states while the package is in C0.

7.2.2.2 Package C1/C1E State

The package will enter the C1/C1E low power state when at least one core is in the C1/C1E state and the rest of the cores are in the C1/C1E or lower power state. The processor will also enter the C1/C1E state when all cores are in a power state lower than C1/C1E but the package low power state is limited to C1/C1E using the PMG_CST_CONFIG_CONTROL MSR. In the C1E state, the processor will automatically transition to the lowest power operating point (lowest supported voltage an d associated frequency). When entering the C1E state, the processor will first switch to the lowest bus ratio and then transition to the lower VID. No notification to the system occurs upon entry to C1/C1E.

7.2.2.3 Package C3 State

The package will enter the C3 low power state when all cores are in the C3 or lower power state and the processor has been granted permission by the other component(s) in the system to enter the C3 state. The package will also enter the C3 state when all cores are in an idle state lower than C3 but other component(s) in the system have only granted permission to enter C3.

Datasheet 85

If Intel QPI L1 has been granted, the processor will disable some clocks and PLLs and for processors with an integrated memory controller, the DRAM will be put into selfrefresh.

7.2.2.4 Package C6 State

The package will enter the C6 low power state when all cores are in the C6 or lower power state and the processor has been granted permission by the other component(s) in the system to enter the C6 state. The package will also enter the C6 state when all cores are in an idle state lower than C6 but the other component(s) have only granted permission to enter C6.

If Intel QPI L1 has been granted, the processor will disable some clocks and PLLs and the shared cache will enter a deep sleep state. Additionally, for processors with an integrated memory controller, the DRAM will be put into self-refresh.

7.3 Sleep States

The processor supports the ACPI sleep states S0, S1, S3, and S4/S5 as shown in

Table 7-3. For information on ACPI S-states and related terminology, refer to ACPI

Specification. The S-state transitions are coordinated by the processor in response PM Request (PMReq) messages from the chipset. The processor itself will never request a particular S-state.

This technology opportunistically and automatically allows the processor to run faster than its marked frequency if the processor is operating below power, thermal, and current specifications.

The processor features Enhanced Intel SpeedStep Technology. Following are the key features of Enhanced Intel SpeedStep Technology:

• Multiple voltage and frequency operating points pro vide optimal performance at the lowest power.

• Voltage and frequency selection is software controlled by writing to processor MSRs:

— If the target frequency is higher than the current frequency, VCC is ramped up

in steps by placing new values on the VID pins and the PLL then locks to the new frequency.

— If the target frequency is lower than the current frequency , the PLL locks to the

new frequency and the VCC is changed through the VID pin mechanism.

— Software transitions are accepted at any time. If a previous transition is in

progress, the new transition is deferred until the previous transition completes.

• The processor controls voltage ramp rates internally to ensure smooth transitions.

• Low transition latency and large number of transitions possible per second:

— Processor core (including shared cache) is unavailable for less than 5 µs during

the frequency transition.

8.2.2 Boxed Processor Fan Heatsink Weight

The boxed processor fan heatsink will not weigh more than 550 grams. See Chapter 6 and the appropriate processor Thermal and Mechanical Design Guidelines (see

Section 1.2). for details on the processor weight and heatsink requirements.

8.2.3 Boxed Processor Retention Mechanism and Heatsink Attach Clip Assembly

The boxed processor thermal solution requires a heatsink attach clip assembly, to secure the processor and fan heatsink in the baseboard socket. The boxed processor will ship with the heatsink attach clip assembly.

8.3 Electrical Requirements

8.3.1 Fan Heatsink Power Supply

The boxed processor fan heatsink requires a +12 V power supply. A fan power cable will be shipped with the boxed processor to draw power from a power header on the baseboard. The power cable connector and pinout are shown in Figure 8-5. Baseboards must provide a matched power header to support the boxed processor. Table 8-1 contains specifications for the input and output signals at the fan heatsink connector.

The fan heatsink outputs a SENSE signal, which is an open- collector output that pulses at a rate of 2 pulses per fan revolution. A baseboard pull-up resistor provides V match the system board-mounted fan speed monitor requirements, if applicable. Use of the SENSE signal is optional. If the SENSE signal is not used, pin 3 of the connector should be tied to GND.

The fan heatsink receives a PWM signal from the motherboard from the 4th pin of the connector labeled as CONTROL.

The boxed processor's fanheat sink requires a constant +12 V supplied to pin 2 and does not support variable voltage control or 3-pin PWM control.

The power header on the baseboard must be positioned to allow the fan heatsink power cable to reach it. The power header identification and location should be documented in the platform documentation, or on the system board itself. Figure 8-6 shows the location of the fan power connector relative to the processor socket. The baseboard power header should be positioned within 110 mm [4.33 inches] from the center of the processor socket.

8.4 Thermal Specifications

This section describes the cooling requirements of the fan heatsink solution used by the boxed processor.

8.4.1 Boxed Processor Cooling Requirements

The boxed processor may be directly cooled with a fan heatsink. Howev er, meeting the processor's temperature specification is also a function of the thermal design of the entire system, and ultimately the responsibility of the system integrator. The processor temperature specification is found in Chapter 6 of this document. The boxed processor fan heatsink is able to keep the processor temperature within the specifications (see

Table 6-1) in chassis that provide good thermal management. For the boxed processor

fan heatsink to operate properly, it is critical that the airflow provided to the fan heatsink is unimpeded. Airflow of the fan heatsink is into the center and out of the sides of the fan heatsink. Airspace is required around the fan to ensure that the airflow through the fan heatsink is not blocked. Blocking the airflow to the fan heatsink reduces the cooling efficiency and decreases fan life. Figure 8-7 and Figure 8-8 illustrate an acceptable airspace clearance for the fan heatsink. The air temperature entering the fan should be kept below 40 ºC. Again, meeting the processor's temperature specification is the responsibility of the system integrator.

8.4.2 Variable Speed Fan

If the boxed processor fan heatsink 4-pin connector is connected to a 3-pin motherboard header it will operate as follows:

The boxed processor fan will operate at different speeds over a short range of internal chassis temperatures. This allows the processor fan to operate at a lower speed and noise level, while internal chassis temperatures are low. If internal chassis temperature increases beyond a lower set point, the fan speed will rise linearly with the internal temperature until the higher set point is reached. At that point, the fan speed is at its maximum. As fan speed increases, so does fan noise levels. Systems should be designed to provide adequate air around the boxed processor fan heatsink that remains cooler then lower set point. These set points, represented in Figure 8-9 and Table 8-2, can vary by a few degrees from fan heatsink to fan heatsink. The internal chassis temperature should be kept below 40 ºC. Meeting the processor temperature specification (see Chapter 6) is the responsibility of the system integrator.

The motherboard must supply a constant +12 V to the processor's power header to ensure proper operation of the variable speed fan for the boxed processor. Refer to

Table 8-1 for the specific requirements.

When the internal chassis temperature is below or equal to this set point, the fan operates at its lowest speed. Recommended maximum internal chassis temperature for nominal operating environment.

When the internal chassis temperature is above or equal to this set point, the fan operates at its highest speed. Recommended maximum internal chassis temperature for worst-case operating environment.

Boxed Processor Fan Speed Notes

Boxed Processor Specifications

If the boxed processor fan heatsink 4-pin connector is connected to a 4-pin motherboard header and the motherboard is designed with a fan speed controller with PWM output (CONTROL see Table 8-1) and remote thermal diode measurement capability the boxed processor will operate as follows:

As processor power has increased the required thermal solutions have generated increasingly more noise. Intel has added an option to the boxed processor that allows system integrators to have a quieter system in the most common usage.

The 4th wire PWM solution provides better control over chassis acoustics. This is achieved by more accurate measurement of processor die temperature through the processor's Digital Thermal Sensors (D TS) and PECI. F an RPM is modulated through the use of an ASIC located on the motherboard that sends out a PWM control signal to the 4th pin of the connector labeled as CONTROL. The fan speed is based on actual processor temperature instead of internal ambient chassis temperatures.

If the new 4-pin active fan heat sink solution is connected to an older 3-pin baseboard processor fan header it will default back to a thermistor controlled. Under thermistor controlled mode, the fan RPM is automatically varied based on the Tinlet temperature measured by a thermistor located at the fan inlet.

For more details on specific motherboard requirements for 4-wire based fan speed control, see the appropriate processor Thermal and Mechanical Design Guidelines (see

Section 1.2).
