▶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.

[Disabled]

Enables the requested cache line only.

▶CPU AES Instructions [Enabled]

Enables or disables the CPU AES (Advanced Encryption Standard-New Instructions) support. This item appears when a CPU supports this function.

[Enabled]

Enables Intel AES support.

[Disabled]

Disables Intel AES support.

▶Intel Adaptive Thermal Monitor [Enabled]

Enables or disables the Intel adaptive thermal monitor function to protect the CPU from overheating.

[Enabled]

Throttles down the CPU core clock speed when the CPU is over the

 

adaptive temperature.

[Disabled]

Disables this function.
