CPU Configuration
► Thermal Management
Thermal Monitor 1 (TM1) is implemented in Pentium 4, Xeon and Pentium M processors. It is
a CPU clock modulation mechanism which prevents CPU overheating in emergency cases by
reducing duty cycle of the processor for up to 46%. The task of this mechanism is to maintain
the CPU temperature at maximum safe level by decreasing its performance, or, in terms, by
reducing CPU Load.
Thermal Monitor 2 (TM2) is an advanced mechanism of CPU overheating protection. A
considerable difference is that TM2 can control the frequency and CPU voltage, while TM1
only modulates CPU clock. Due to reduced voltage, TM2 allows to retain better processor
performance in case of overheating at the same reduction of power consumption level.
TM2 is recommended for 2.8 GHz processors and higher (166 MHz bus) and 3.6 GHz
and higher (200 MHz bus), while TM1 is recommended for junior models. This item will be
displayed only when the CPU supports this feature.
► EIST function
You can select the EIST (Processor Power Management, PPM) through this item.
► C1E Function
C1E represents Enhanced HALT State. It is a feature which Intel CPU uses to reduce power
consumption when in halt state. C1E drops the CPU's multiplier and voltage to lower levels
when a HLT (halt) command is issued. This item is used to enable/disable the C1E support.
Enhanced Intel SpeedStep® technology (EIST) allows the system to dynamically
adjust processor voltage and core frequency, which can result in decreased average
power consumption and decreased average heat production. There are some system
requirements must be met, including CPU, chipset, motherboard, BIOS and operation
system. Please refer to Intel website for more information.
