▶CPU Features

Press <Enter> to enter the sub-menu. ▶Hyper-Threading

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.

▶Active Processor Cores

This item allows you to select the number of active processor cores.

▶Limit CPUID Maximum

It is designed to limit the listed speed of the processor to older operating systems.

▶Execute Disable Bit

Can prevent certain classes of malicious “buffer overflow” attacks where worms can try to execute code to damage your system. It is recommended you keep this en- abled always.

▶Intel Virtualization Tech

Enhances virtualization and allows the system to act as multiple virtual systems. See Intel’s official website for more information.

▶Intel VT-D Tech

This item is used to enable/disable the Intel VT-D technology. For further information please refer to Intel’s official website.

▶Power Technology

This item allows you to select the Intel Dynamic Power technology mode.

▶C1E Support

Enable system to reduce CPU power consumption while idle. Not all processors support Enhanced Halt state (C1E).

▶OverSpeed Protection

Monitors current CPU draw as well as power consumption; if it exceeds a certain level, the processor automatically reduces its clock speed. For overclocking, it is recommended this feature is disabled.

▶Intel C-State

C-state is a power management state that detects when the system is idle and lowers power consumption accordingly.
