This is a display that indicates the speed of the installed processor.
This feature enables you to set the internal frequency multiplier for the CPU. The options are:
Default, x12, x13, x14, x15, x16, x17 and x18.
Set to Enabled to use a processor's second core and beyond. (Please refer to Intel's web site for
more information.) The options are Disabled and Enabled.
Set to Enabled to activate the function of Machine Checking and allow the CPU to detect and
report hardware (machine) errors via a set of model-specific registers (MSRs). The options are
Disabled and Enabled.
Set to Enabled to use Thermal Management 2 (TM2), which will lower CPU voltage and
frequency when the CPU temperature reaches a predefined overheat threshold. Set to Disabled to
use Thermal Manager 1 (TM1), allowing CPU clocking to be regulated via CPU Internal Clock
modulation when the CPU temperature reaches the overheat threshold.
Select Disable to disable the Standard C1 Halt State, which will partially turns off the CPU
internal clocks to conserve energy and prevent system overheating when the OS is idle. Select
Enable to use the Enhanced C1 Halt State to lower the CPU clock frequency and the supply
voltage before turning off the clocks.
