Hyper-Threadng Functon
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.

Execute Bt Support
Intel’s Execute Dsable Bt functonalty can prevent certan classes of malcous
“bu󰘯er over󰘱ow” attacks when combned wth a supportng operatng system. Ths
functonalty allows the processor to classfy areas n memory by where applcaton
code can execute and where t cannot. When a malcous worm attempts to nsert
code n the bu󰘯er, the processor dsables code executon, preventng damage or
worm propagaton.
Set Lmt CPUID MaxVal to 3
The Max CPUID Value Lmt s desgned lmt the lsted speed of the processor to
older operatng systems.
Intel Vrtualzaton Tech
Ths tem s used to enable/dsable the Intel Vrtualzaton technology. For further
nformaton please refer to Intel’s o󰘲cal webste.
Intel EIST
The Enhanced Intel SpeedStep technology allows you to set the performance level of
the mcroprocessor whether the computer s runnng on battery or AC power. Ths 󰘰eld
wll appear after you nstalled the CPU whch supports speedstep technology.
C1E Support
To enable ths tem to read the CPU power consumpton whle dle. Not all processors
support Enhanced Halt state (C1E).
Intel Turbo Boost
Ths tem wll appear when you nstall a CPU wth Intel Turbo Boost technology. Ths
tem s used to enable/ dsable Intel Turbo Boost technology. It can scale processor
frequency hgher dynamcally when applcatons demand more performance and TDP
headroom exsts. It also can delver seamless power scalablty (Dynamcally scale up,
Speed-Step Down). It s the Intel newly technology wthn 3/ 5/ 7 CPU.
