Hyper-Threadng Functon
The processor uses Hyper-Threadng technology to ncrease transacton rates and
reduces end-user response tmes. The technology treats the two cores nsde the
processor as two logcal processors that can execute nstructons smultaneously. In
ths way, the system performance s hghly mproved. If you dsable the functon, the
processor wll use only one core to execute the nstructons. Please dsable ths tem
f your operatng system doesn’t support HT Functon, or unrelablty and nstablty
may occur.
Important
Enablng the functonalty of Hyper-Threadng Technology for your computer system
requres ALL of the followng platform Components:
CPU: An Intel
®
Processor wth HT Technology;
Chpset: An Intel
®
Chpset that supports HT Technology;
BIOS: A BIOS that supports HT Technology and has t enabled;
OS: An operatng system that supports HT Technology.

Execute Bt Support
Intel’s Execute Dsable Bt functonalty can prevent certan classes of malcous
“buffer overflow” attacks when combned wth a supportng operatng system. Ths
functonalty allows the processor to classfy areas n memory by where applcaton
code can execute and where t cannot. When a malcous worm attempts to nsert
code n the buffer, the processor dsables code executon, preventng damage or
worm propagaton.
Set Lmt CPUID MaxVal to 3
The Max CPUID Value Lmt s desgned lmt the lsted speed of the processor to
older operatng systems.
Intel Vrtualzaton Tech
Ths tem s used to enable/dsable the Intel Vrtualzaton technology. For further
nformaton please refer to Intel’s offical webste.
Actve Processor
Ths tem allows you to select the number of actve processor cores.
Intel EIST
The Enhanced Intel SpeedStep technology allows you to set the performance level of
the mcroprocessor whether the computer s runnng on battery or AC power. Ths field
wll appear after you nstalled the CPU whch supports speedstep technology.
C1E Support
To enable ths tem to read the CPU power consumpton whle dle. Not all processors
support Enhanced Halt state (C1E).
Intel Turbo Boost
Ths tem wll appear when you nstall a CPU wth Intel Turbo Boost technology. Ths
tem s used to enable/ dsable Intel Turbo Boost technology. It can scale processor
