Notes: 1. TDP shown here, 95 W for example, represents the maximum expected platform TDP in the next generation

platform for this type of SKU. This placeholder value is provided as a guideline for hardware design for the next

generation platform.

2. Platform Compatibility Guide (PCG) provides a design target for meeting all planned processor frequency

 on page 94.

3. Package Thermal Design Power (TDP) is for the Intel

®

 Xeon

®

 processor E3-1200 v3 Product Family.

4. Platform Thermal Design Power (TDP) includes projections for the refresh processor that follow the Intel

processor E3-1200 v3 Product Family in this platform.

5. Thermal Solution information can be found in the following table.
6. These boundary conditions and performance targets are used to generate processor thermal specifications and to

provide guidance for heatsink design. Values are for the heatsink shown in the adjacent column are calculated at sea

level, and are expected to meet the Thermal Profile at TDP. T

LA

 is the local ambient temperature of the heatsink

inlet air. Airflow is through the heatsink fins with zero bypass for a passive heatsink. RPM is fan revolutions per

minute for an active heatsink. Ѱ

CA

 is the maximum target (mean + 3 sigma) for the thermal characterization

parameter. For more information on the thermal characterization parameter, refer to the processor Thermal

Mechanical Design Guidelines (see Related Documents section).

7. Maximum T

CASE

 Thermal Profile is the specification that must be complied to. Any Attempt to operate the processor

outside these operating limits may result in permanent damage to the processor and potentially other system

components.

8. T

CASE-MAX

 at Platform TDP is calculated using the maximum T

CASE

 Thermal Profile and the platform TDP.

9. ATCA Reference Heatsink supports Socket B and is not tooled for Socket H.

A software readable field in the 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.

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
