Processor Thermal Features
6.2.1
Intel® Thermal Monitor Features
Intel® Xeon® Processor 7400 Series provide two thermal monitor features, Intel®
Thermal Monitor (TM1) and Enhanced Thermal Monitor (TM2). The TM1 and TM2 must
both be enabled in BIOS for the processor to be operating within specifications. When
both are enabled, TM2 will be activated first and TM1 will be added if TM2 is not
effective.

Intel Thermal Monitor
The Intel Thermal Monitor (TM1) 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
needed by modulating (starting and stopping) the internal processor core clocks. The
Intel Thermal Monitor or Enhanced Thermal Monitor (Thermal Monitor 2) must be
enabled for the processor to be operating within specifications. The temperature at
which Thermal Monitor activates the thermal control circuit is not user configurable and
