▶ C1E Support
To enable ths tem to read the CPU power consumpton whle dle. Not all processors
support Enhanced Halt state (C1E).
▶ OverSpeed Protecton
Overspeed Protecton functon can montor the current CPU draws as well as ts
power consumpton. If t exceeds a certan level, the processor automatcally reduces
ts clock speed. If you want to overclock your CPU, set t to [Dsabled].
▶ 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 web-ste.
▶ Intel VT-d
Ths tem s used to enable/dsable the Intel Vrtualzaton Technology for Drected
I/O (VT-d). For further nformaton please refer to Intel's offical webste.
