5.1.3 Processor Operational Thermal Specifications
Each SKU has a unique thermal profile that ensures reliable operation for the intended
form factor over the processor’s service life. These specifications are based on final
silicon characterization.
5.1.3.1 Minimum operating case temperature
Minimum case operating temperature is specified at 5°C for every Intel® Xeon®
processor E5-2400 v2 product family processor SKU.
5.1.3.2 Maximum operating case temperature thermal profiles
Temperature values are specified at VCC_MAX for all processor frequencies. Systems
must be designed to ensure the processor is not to be subjected to any static VCC and
ICC combination wherein VCC exceeds VCC_MAX at specified ICC. Please refer to the
electrical loadline specifications in Chapter 7.
Thermal Design Power (TDP) should be used for processor thermal solution design
targets. TDP is not the maximum power that the processor can dissipate. TDP is
measured at specified maximum T
CASE
.
Power specifications are defined at all VID values found in Table 7-3. The Intel® Xeon®
processor E5-2400 v2 product family may be delivered under multiple VIDs for each
frequency. Implementation of a specified thermal profile should result in virtually no
TCC activation. Furthermore, utilization of thermal solutions that do not meet the
specified thermal profile will result in increased probability of TCC activation and may
incur measurable performance loss. Refer to the
Intel® Xeon® Processor E5-2400 v2
Product Family Thermal/Mechanical Design Guide (TMDG)
for system and
environmental implementation details.
Each case temperature thermal profile is unique to each TDP and core count
combination. These T
CASE
profiles are fully defined by the simple linear equation:
T
CASE
= PSI
CA
* P + T
LA
Where:
PSI
CA
is the Case-to-Ambient thermal resistance of the processor thermal solution.
T
LA
is the Local Ambient temperature.
P is the processor power dissipation.
Table 5-1 provides the
PSI
CA
and T
LA
parameters that define T
CASE
thermal profile for
each TDP/Core count combination. Figure 5-1 illustrates the general form of the
resulting linear graph resulting from
T
CASE
= PSI
CA
* P + T
LA
.
