Chapter 3 MS-7673 ▶ X.M.P Support Information Press to enter the sub-menu. These items display the current status of the X.M.P support information. Read only. ▶ CPU Feature Press to enter the sub-menu and the following screen appears: ▶ Hyper-threading The processor uses Hyper-Threading technology to increase transaction rates and reduces end-user response times. The technology treats the two cores inside the processor as two logical processors that can execute instructions simultaneously. In this way, the system performance is highly improved. If you disable the function, the processor will use only one core to execute the instructions. Please disable this item if your operating system doesn't support HT Function, or unreliability and instability may occur. Important Enabling the functionality of Hyper-Threading Technology for your computer system requires ALL of the following platform Components: • CPU: An Intel® Processor with HT Technology; • Chipset: An Intel® Chipset that supports HT Technology; • BIOS: A BIOS that supports HT Technology and has it enabled; • OS: An operating system that supports HT Technology. For more information on Hyper-threading Technology, go to: http://www.intel.com/products/ht/hyperthreading_more.htm ▶ Active Processor Cores This item allows you to select the number of active processor cores. ▶ Limit CPUID Maximum It is designed to limit the listed speed of the processor to older operating systems. 3-11

X.M.P Support Informat±on
Press <Enter> to enter the sub-menu. These ±tems d±splay the current status of the
X.M.P support ±nformat±on. Read only.
CPU Feature
Press <Enter> to enter the sub-menu and the follow±ng screen appears:
Hyper-thread±ng
The processor uses Hyper-Thread±ng technology to ±ncrease transact±on rates and
reduces end-user response t±mes. The technology treats the two cores ±ns±de the
processor as two log±cal processors that can execute ±nstruct±ons s±multaneously.
In
th±s way, the system performance ±s h±ghly ±mproved. If you d±sable the funct±on, the
processor w±ll use only one core to execute the ±nstruct±ons. Please d±sable th±s ±tem
±f your operat±ng system doesn’t support HT Funct±on, or unrel±ab±l±ty and ±nstab±l±ty
may occur.
Important
Enabl±ng the funct±onal±ty of Hyper-Thread±ng Technology for your computer system
requ±res ALL of the follow±ng platform Components:
CPU: An Intel
®
Processor w±th HT Technology;
Ch±pset: An Intel
®
Ch±pset that supports HT Technology;
BIOS: A BIOS that supports HT Technology and has ±t enabled;
OS: An operat±ng system that supports HT Technology.

Act±ve Processor Cores
Th±s ±tem allows you to select the number of act±ve processor cores.
L±m±t CPUID Max±mum
It ±s des±gned to l±m±t the l±sted speed of the processor to older operat±ng systems.
