▶ Processor Configuration
This menu shows the processor information.
▶
Hyper-Threading (ALL)
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.
▶ 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 exe -
cution, preventing damage or worm propagation.
▶ Hardware Prefetcher
The processor has a hardware prefetcher that automatically analyzes its re -
quirements and prefetches data and instructions from the memory into the
Level 2 cache that are likely to be required in the near future. This reduces
the latency associated with memory reads. When enabled, the processor’s
hardware prefetcher will be enabled and allowed to automatically prefetch
data and code for the processor. When disabled, the processor’s hardware
prefetcher will be disabled.
