 CPU Speed
This item displays the speed of the CPU installed in Socket 0.
 64-bit
This item indicates if the CPU installed in Socket 0 supports 64-bit technology.
 Active Processor Cores
Set to Enabled to use a processor's second core and above. (Please refer to Intel's website
for more information.) The options are All, 1, and 2.
 Limit CPUID Maximum
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 (for the Windows OS).
 Execute-Disable Bit Capability (Available if supported by the OS & the CPU)
Select 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.)
 Hardware Prefetcher (Available when supported by the CPU)
If set to Enabled, the hardware prefetcher will prefetch streams of data and instructions from
the main memory to the L2 cache to improve CPU performance. The options are Disabled
and Enabled
 Adjacent Cache Line Prefetch (Available when supported by the CPU)
The CPU prefetches the cache line for 64 bytes if this feature is set to Disabled. The CPU
prefetches both cache lines for 128 bytes as comprised if this feature is set to Enabled
 DCU Streamer Prefetcher (Available when supported by the CPU)
Select Enabled to support Data Cache Unit (DCU) prefetch to speed up data accessing and
processing in the DCU to enhance CPU performance. The options are Disabled and
Enabled
 DCU IP Prefetcher
Select Enabled for DCU (Data Cache Unit) IP Prefetcher support, which will prefetch IP
addresses to improve network connectivity and system performance. The options are
Enabled and Disabled
