Advanced Processor Options
Access the submenu to make changes to the following settings.
CPU Speed
This is a display that indicates the speed of the installed processor.
Frequency Ratio
(*Available when supported by the CPU.)
The feature allows the user to set the internal frequency multiplier for the CPU.
The options are: Default, x12, x13, x14, x15, x16, x17 and x18.
Hyper-threading
(*Available when supported by the CPU.)
Set to Enabled to use the Hyper-Threading Technology, which will result in increased
CPU performance. The options are Disabled and Enabled.
Core-Multi-Processing
(*Available when supported by the CPU.)
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.
Machine Checking
(*Available when supported by the CPU.)
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-specifi c registers
(MSRs). The options are Disabled and Enabled.
Thermal Management 2
(*Available when supported by the CPU.)
Set to Enabled to use Thermal Management 2 (TM2) which will lower CPU voltage
and frequency when the CPU temperature reaches a predefi ned 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.
C1 Enhanced Mode
(*Available when supported by the CPU.)
Select Disable to disable the Standard C1 Halt State which will partially turn 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.
Execute Disable Bit
(*Available when supported by the CPU and the OS.)
Set to Enabled to enable Execute Disable Bit and allow the processor to classify
areas in memory where an application code can be executed and where it cannot,
and thus preventing a worm or a virus from inserting and creating a fl ood of codes
to overwhelm the processor or damage the system during an attack.
The options are Disabled and Enabled. (Note: For more information regarding
hardware/software support for this function, please refer to Intel's and Microsoft's
web sites.)
