MS-7666 Mainboard

C State Package Limit Setting

This feild allows you to select a C-state level. We recommand that you leave this

setting to Auto.

C1E Support

To enable this item to read the CPU power consumption while idle. Not all processors

support Enhanced Halt state (C1E).

OverSpeed Protection

Overspeed Protection function can monitor the current CPU draws as well as its

power consumption. If it exceeds a certain level, the processor automatically reduces

its clock speed. If you want to overclock your CPU, set it to [Disabled].

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

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

Chipset that supports HT Technology;

BIOS: A BIOS that supports HT Technology and has it enabled;

OS: An operating system that supports HT Technology.

Execute Bit Support

Intel’s Execute Disable Bit functionality can prevent certain classes of malicious

“buer over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 buer, the processor disables code execution, preventing damage or

worm propagation.

Set Limit CPUID MaxVal to 3

The Max CPUID Value Limit is designed limit the listed speed of the processor to

older operating systems.

Intel Virtualization Tech

This item is used to enable/disable the Intel Virtualization technology. For further

information please refer to Intel’s ocial website.
