Hyper-Threading
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 nstruc-
tons 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.

Active Processor Cores
Ths settng specfes the number of actve processor cores.

Execute Disable Bit
Intel's Execute Dsable Bt functonalty can prevent certan classes of mal-
cous "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 execu-
ton, preventng damage or worm propagaton.
▶
Intel Virtualization Technology
Vrtualzaton enhanced by Intel Vrtualzaton Technology wll allow a platform
to run multple operatng systems and applcatons n ndependent parttons.
Wth vrtualzaton, one computer system can functon as multple "Vrtual"
systems.
▶
EIST
EIST (Enhanced Intel SpeedStep Technology) allows the system to dynam-
cally adjust processor voltage and core frequency, whch can result n de-
creased average power consumpton and decreased average heat produc-
ton. When dsabled, the processor wll return the actual maxmum CPUID
nput value of the processor when quered.
