X7DCU User's Manual
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 if supported by the CPU.)
Set to Enabled to enable Enhanced Halt (C1) State to lower CPU voltage/frequency
to prevent the processor from overheating. The options are Enabled and Disabled.
Please refer to Intel’s web site for details.)
Execute Disable Bit (Available if supported by the CPU.)
Set to Enabled to allow the processor to classify areas in memory where an ap-
plication code can execute 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.
For more information regarding this function, please refer to Intel's and Microsoft's
web sites.

Series Processors.
Hardware Prefetcher (Available if supported by the CPU.)
Set to Enabled to activate the hardware components that are used in conjunction
with software programs to prefetch data in order to shorten execution cycles and
maximize data processing effi ciency. The options are Disabled and Enabled.
Intel <R> Virtualization Technology (Available when supported by the CPU.)
Select Enabled to use the feature of Virtualization Technology to allow one platform
to run multiple operating systems and applications in independent partitions, creat-
ing multiple "virtual" systems in one physical computer. The options are Enabled
and Disabled.
Note: If there is any change to this setting, you will need to power off and
restart the system for the change to take effect. Please refer to Intel’s
