CPU Feature
Hyper-Threading Function
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 instructions
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.
Execute Bit Support
Intel's Execute Disable Bit functionality can prevent certain classes of malicious
"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. W hen a malicious worm
attempts to insert code in the buffer, the processor disables code execution,
preventing damage or worm propagation.
