off and restart the system for the change to take effect. Please refer to Intel’s web
site for detailed information.
ExecuteDisableBit(AvailablewhensupportedbytheOSandtheCPU)
Set to Enabled to enable the Execute Disable Bit to allow the processor to classify
areas in the system memory where an application code can execute and where
it cannot, thus preventing a worm or a virus from creating a ood of codes to
overwhelm the processor or damage the system during an attack. The default is
Enabled. (Refer to Intel and Microsoft Web Sites for more information.)
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.
PECI
Select Enabled to activate the processor's Platform Environment Control Interface
(PECI) feature. PECI uses the processor's Digital Thermal Sensor (DTS) to man-
age thermal conditions. Please see the item CPU Overheat Alarm under Hard-
wareHealthConguration later in this section for more information. The options
are Enabled and Disabled.
Intel® Speed Step
TM
Technology(AvailablewhensupportedbytheCPU)
Select Enabled to use the Enhanced Intel SpeedStep Technology and allow the
system to automatically adjust the processor voltage and core frequency in an ef-
fort to reduce power consumption and heat dissipation. The options are Enabled
and Disable.
Intel®C-StateTechnology(AvailablewhensupportedbytheCPU)
Select Enabled to use the Intel C-State Technology and allow the BIOS to automati-
cally set the system power to C2/C3/C4 State in an effort to reduce power consump-
tion and heat dissipation. The options are Enabled and Disabled.
C1E Support
Select Enabled to use the "Enhanced Halt State" feature. C1E signicantly reduces
the CPU's power consumption by reducing the CPU's clock cycle and voltage during
a "Halt State." The options are Disabled and Enabled.
