BIOS Setup
▶ CPU Configuration
▶ Hyper-Threading
The processor uses Hyper-Threading technology to increase transaction
rates and reduces end-user response times. The technology treats the two
cores inside the processor as two logical processors that can execute instruc-
tions simultaneously. In this way, the system performance is highly improved.
If you disable the function, the processor will use only one core to execute the
instructions. Please disable this item if your operating system doesn't support
HT Function, or unreliability and instability may occur.
▶ Active Processor Cores
This setting specifies the number of active processor cores.
▶ Execute Disable Bit
Intel's Execute Disable Bit functionality can prevent certain classes of mali-
cious "buffer overflow" attacks when combined with a supporting operating
system. This functionality allows the processor to classify areas in memory by
where application code can execute and where it cannot. When a malicious
worm attempts to insert code in the buffer, the processor disables code execu-
tion, preventing damage or worm propagation.
▶ Intel Virtualization Technology
Virtualization enhanced by Intel Virtualization Technology will allow a platform
to run multiple operating systems and applications in independent partitions.
With virtualization, one computer system can function as multiple "Virtual"
systems.
▶ EIST
EIST (Enhanced Intel SpeedStep Technology) allows the system to dynami-
cally adjust processor voltage and core frequency, which can result in de-
creased average power consumption and decreased average heat produc-
tion. When disabled, the processor will return the actual maximum CPUID
input value of the processor when queried.
