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.
Intel C-STATE
C-state s a power management state that sgn󰘰cantly reduces the power of the
processor durng dle. Ths 󰘰eld wll appear after you nstalled the CPU whch
supports c-state technology.
C State Package Lmt Settng
Ths feld allows you to select a C-state level. We recommand that you leave ths
settng to Auto.
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).
OverSpeed Protecton
Overspeed Protecton functon can montor the current CPU draws as well as ts
power consumpton. If t exceeds a certan level, the processor automatcally reduces
ts clock speed. If you want to overclock your CPU, set t to [Dsabled].
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.
