CPU Configuration
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
This setting specifies the number of active processor cores.
Limit CPUID Maximum
Ths feature allows you to crcumvent problems wth older operatng systems
that do not support the Intel Pentum 4 processor wth Hyper-Threadng Tech-
nology. When enabled, the processor wll lmt the maxmum CPUID nput
value to 03h when quered, even f the processor supports a hgher CPUID
nput value. When dsabled, the processor wll return the actual maxmum
CPUID nput value of the processor when quered.
Execute Disable Bit
Intel’s Execute Dsable Bt functonalty can prevent certan classes of mal-
cious “buffer overflow” attacks when combined with a supporting operating
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.
