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.
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.
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-
specific registers (MSRs). The options are Disabled and
Enabled
.
C1 Enhanced Mode
(
*
Available when supported by the CPU.)
Set to Enabled to enable Enhanced Halt State to lower CPU voltage/fre-
quency to prevent overheat. The options are Enabled and
Disabled
.
(
*Note:
please refer to Intel’s web site for detailed information.)
No Execute Mode Memory Protection
(
*
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 execute and
where it cannot, and thus preventing a worm or a virus from inserting and
creating a flood of codes to overwhelm the processor or damage the
system during an attack.
(*Note: this feature is available when your OS and your CPU support the
function of Execute Disable Bit.) 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.)
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 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.
