Thermal Specifications
Notes:
1.
Thermal Profile A is representative of a volumetrically unconstrained platform. Please refer to
Table 6-5 for
discrete points that constitute the thermal profile.
2.
Implementation of Thermal Profile A should result in virtually no TCC activation. Furthermore, utilization of
thermal solutions that do not meet processor Thermal Profile A will result in increased probability of TCC
activation and may incur measurable performance loss. (Refer to
Section 6.2 for details on TCC activation).
3.
Thermal Profile B is representative of a volumetrically constrained platform. Please refer to
Table 6-6 for
discrete points that constitute the thermal profile.
4.
Implementation of Thermal Profile B will result in increased probability of TCC activation and measurable
performance loss. Furthermore, utilization of thermal solutions that do not meet Thermal Profile B do not
meet the processor’s thermal specifications and may result in permanent damage to the processor.
5.
Refer to the Dual-Core Intel Xeon Processor 5000 Series Thermal/Mechanical Design Guidelines for
system and environmental implementation details.
