▶ Hyper-Threading Function 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.
Important Important
Enabling the functionality of Hyper-Threading Technology for your computer system
requires ALL of the following platform Components:
CPU: An Intel Processor with HT Technology;
•
®
• Chipset: An Intel
• BIOS: A BIOS that supports HT Technology and has it enabled;
• OS: An operating system that supports HT Technology.

▶ Execute Bit Support Execute Bit Support
Intel's Execute Disable Bit functionality can prevent certain classes of malicious
"buff er overfl ow" 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 buff er, the processor disables code execution, preventing damage or
worm propagation.
▶ Set Limit CPUID MaxVal to 3 Set Limit CPUID MaxVal to 3
The Max CPUID Value Limit is designed limit the listed speed of the processor to
older operating systems.
