Processor and Clock Options

This submenu allows the user to confi gure the Processor and Clock settings.
CPU Ratio
If set to Manual, this option allows the user to set the ratio between the CPU Core
Clock and the FSB Frequency. (Note: if an invalid ratio is entered, the AMI BIOS
will restore the setting to the previous state.) The options are Auto and Manual.
Ratio CMOS Setting (Available when the item-CPU Ratio is set to
Enabled)
Press "+" or "-" on your keyboard to set the ratio between the CPU Core clock
and the FSB Frequency. The default setting for the CPU installed in your moth-
erboard is [21].
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. The options are Disabled and Enabled.
Hardware Prefetcher (Available when supported by the CPU)
If set to Enabled, the hardware prefetcher will prefetch 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 fl ooding 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.)
