your overclocked processor to lock up.

▶ CPU Features

Press <Enter> to enter the sub-menu.

▶ Hyper-Threading Technology [Enabled]

The processor uses Hyper-Threading technology to increase transaction rates and reduces end-user response times. Intel Hyper-Threading technology treats the multi cores inside the processor as multi logical processors that can execute instructions simultaneously. In this way, the system performance is highly improved.

[Enable]

Enables Intel Hyper-Threading technology.

[Disabled]

Disables this item if the system does not support HT function.

▶ Active Processor Cores [All]

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

▶ Limit CPUID Maximum [Disabled]

Enables or disables the extended CPUID value.

[Enabled]

BIOS will limit the maximum CPUID input value to circumvent

 

boot problems with older operating system that do not support

 

the processor with extended CPUID value.

[Disabled]

Use the actual maximum CPUID input value.

▶ Execute Disable Bit [Enabled]

Intel’s Execute Disable Bit functionality can prevent certain classes of malicious “buffer overflow” attacks where worms attempt to execute code to damage the system. It is recommended that keeps this item enabled always.

[Enabled]

Enables NO-Execution protection to prevent the malicious

 

attacks and worms.

[Disabled]

Disables this function.

▶ Intel Virtualization Tech [Enabled]

Enables or disables Intel Virtualization technology.

[Enabled]

Enables Intel Virtualization technology and allows a platform

 

to run multiple operating systems in independent partitions.

 

The system can function as multiple systems virtually.

[Disabled]

Disables this function.

▶ Hardware Prefetcher [Enabled]

Enables or disables the hardware prefetcher (MLC Streamer prefetcher).

[Enabled]

Allows the hardware prefetcher to automatically pre-fetch

 

data and instructions into L2 cache from memory for tuning

 

the CPU performance.

[Disabled]

Disables the hardware prefetcher.

▶ Adjacent Cache Line Prefetch [Enabled]

Enables or disables the CPU hardware prefetcher (MLC Spatial prefetcher).

[Enabled]

Enables adjacent cache line prefetching for reducing the

 

cache latency time and tuning the performance to the specific

 

application.
