CPU Features
Press to enter the sub-menu and the followng screen appears:
Hyper-threadng
Ths field appears only when the CPU supports 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.
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
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.
