Processor Thermal Features

®
6.2.1 Intel
Quad-Core Intel® Xeon® Processor 5400 Series provides two thermal monitor
features, Intel® Thermal Monitor 1 and Intel® Thermal Monitor 2. The Intel® Thermal
Monitor 1 and Intel® Thermal Monitor 2 must both be enabled in BIOS for the
processor to be operating within specifications. When both are enabled, Intel® Thermal
Monitor 2 will be activated first and Intel® Thermal Monitor 1 will be added if Intel®
Thermal Monitor 2 is not effective.
6.2.1.1 Intel® Thermal Monitor 1
The Intel® Thermal Monitor 1 feature helps control the processor temperature by
activating the Thermal Control Circuit (TCC) when the processor silicon reaches its
maximum operating temperature. The TCC reduces processor power consumption as
