1U Rackmount System
XProcessor & Clock Options
Warning: Take Caution when changing the Advanced settings. An incorrect value, a very high
DRAM frequency or incorrect DRAM timing may cause system to become unstable. When this
occurs, revert to the default setting.
CPU Ratio
This feature allows the user to use the CPU clock multiplier to multiply CPU speed in order to en-
hance performance. Select Manual to Manually set the multiplier set- ting. Select Auto for the BIOS to
automatically select the CPU multiplier setting for your system. The options are Auto and Manual.
Clock Spread Spectrum
Select Enable to use the feature of Clock Spectrum, which will allow the BIOS to monitor and attempt
to reduce the level of Electromagnetic Interference caused by the components whenever needed.
Select Disabled to enhance system stability. The options are Disabled and Enabled.
Hardware Prefetcher (Available when supported by the CPU)
If set to Enabled, the hardware pre fetcher will pre fetch streams of data and instruc- tions from the
main memory to the L2 cache in the forward or backward manner to improve CPU performance. The
options are Disabled and Enabled.
Adjacent Cache Line Prefetch (Available when supported by 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.
Intel® 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 web site for detailed information.
Execute-Disable Bit Capability (Available when supported by the OS and the CPU)
Set to Enabled to enable the Execute Disable Bit which will allow the processor to designate areas
in the system memory where an application code can execute and where it cannot, thus preventing a
worm or a virus from flooding illegal 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.)
