Press <Enter> to enter the sub-menu. The sub-menu dsplays the nformatons of
nstalled memory.
CPU Features
Press <Enter> to enter the sub-menu.
Hyper-Threadng
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.
Actve Processor Cores
Ths tem allows you to select the number of actve processor cores.
Lmt CPUID Maxmum
It s desgned to lmt the lsted speed of the processor to older operatng systems.
Execute Dsable Bt
Can prevent certan classes of malcous “buffer overflow” attacks where worms can
try to execute code to damage your system. It s recommended you keep ths en-
abled always.
Intel Vrtualzaton Tech
Enhances vrtualzaton and allows the system to act as multple vrtual systems. See
Intel’s offical webste for more nformaton.
Intel VT-D Tech
Ths tem s used to enable/dsable the Intel VT-D technology. For further nformaton
please refer to Intel’s offical webste.
Power Technology
Ths tem allows you to select the Intel Dynamc Power technology mode.
C1E Support
Enable system to reduce CPU power consumpton whle dle. Not all processors
support Enhanced Halt state (C1E).
OverSpeed Protecton
Montors current CPU draw as well as power consumpton; f t exceeds a certan
level, the processor automatcally reduces ts clock speed. For overclockng, t s
recommended ths feature s dsabled.
Intel C-State
C-state s a power management state that detects when the system s dle and
lowers power consumpton accordngly.
