X6QT8/X6QTE+ User’s Manual
Adjacent Cache Line Prefetch (*Available when supported by the OS and
the CPU.)
The CPU fetches the cache line for 64 bytes if this option is set to Disabled. The
CPU fetches both cache lines for 128 bytes as comprised if Enabled. The options
are Disabled and Enabled.
Max CPUID Value Limit
This feature allows the user to set the maximum CPU ID value. Enable this function
to boot the legacy operating systems that cannot support processors with extended
CPUID functions. The options are Enabled and Disabled.
Vanderpool Technology (*Available when supported by the CPU.)
Set to Enabled to utilize enhanced virtualization capabilities provided by the Intel
Vanderpool Technology to allow one platform to run multiple operating systems
and applications in independent partitions, creating 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.) 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 fl ood of codes to
overwhelm the processor or damage the system during an attack. (Note: For more
information regarding hardware/software support for this function, please refer to
Intel's and Microsoft's web sites.
Single Logical Processor Mode (*Available when supported by the CPU.)
Select Enabled to allow the processor to operate in the single core mode, allowing
Logical Processor 0 CORE 0 to remain active. The options are Enabled and
Disabled.
Hyper-Threading Technology
This setting allows you to Enable or Disable the function of Hyper-Threading.
Enabling Hyper-Threading results in increased CPU performance.
Intel (R) SpeedStep (tm) Technology (*Available when supported by the
CPU.)
The Enhanced Intel SpeedStep Technology allows the system to automatically adjust
processor voltage and core frequency in an effort to reduce power consumption
and heat dissipation. Select Maximum to set the CPU speed to the maximum.
Select Minimum to set the CPU speed to the minimum. Select Auto to allow the
CPU speed to be controlled by the OS. Select Disabled to disable this feature.
