▶ Intel C-State
C-state is a power management state that significantly reduces the power of the
processor during idle. This field will appear after you installed the CPU which sup-
ports c-state technology.
▶ 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
• 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
"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 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.
