Processor 5100 Series provides two thermal monitor features,
Thermal Monitor (TM1) and Enhanced Thermal Monitor (TM2). The Thermal Monitor
and Enhanced Thermal Monitor 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.

6.2.1.1
Thermal Monitor (TM1)
The 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
temperature at which Thermal Monitor activates the thermal control circuit is not user
configurable and is not software visible. Bus traffic is snooped in the normal manner,
and interrupt requests are latched (and serviced during the time that the clocks are on)
while the TCC is active.
