Thermal Control Circuit
74
Explanation
Used to enable the Thermal Control Circuit (TCC) portion of
the Thermal Monitor feature of the CPU. You can choose:
• TM1
: Thermal Monitor 1. This is the supported mode for
Intel Celeron M processors. If the processor reaches its
critical temperature (100°C/212°F), TM1 modulates the
processor clock, turning it on and off at a 50% duty cycle.
This halves the processor speed and cools it (because
clock speed and power consumption are proportional).
• TM2
: Thermal Monitor 2. For Pentium M processors that
support Enhanced Intel Speedstep and allow for the
processor frequency to be changed from the maximum
processor speed down to 600MHz. In this mode the
thermal monitor can provide maximum performance under
high temperature conditions.
• Disabled
: Disables the TCC, the processor will shutdown
itself down if it's absolute maximum temperature is reached
125°C.
