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 webste.
Intel VT-d Tech
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.
