Network Application Platforms

Item

Selection

Overclocking

lock

Allows overclocking function to be

locked.

Limit CPUID

Maximum

Allows legacy operating systems to boot

even without support CPUs with extend-

ed CPUID functions.

Select to enable or disable this function

Execute Dis-

able Bit

Select to enable or disable the No-Execu-

tion Page Protection Technology.

Intel Virtual-

ization

The Intel VT is a hardware-assisted virtual-

ization. This processor supports Intel Vir-

tualization. Enable or disable this feature.

Hardware

Prefetcher

The processor has a hardware prefetcher

that automatically prefetches data and in-

structions from the memory into the Level

2 cache that are likely to be required in

the near future. This reduces the latency

associated with memory reads.

When enabled, the processor’s hardware

prefetcher will be enabled and allowed to

automatically prefetch data and code for

the processor.

When disabled, the processor’s hardware

prefetcher will be disabled.

Adjacent

Cache Line P

Select to enable or disable prefetching of

adjacent line

CPU AES

Enable or disable the CPU Advanced En-

cryption Standard (AES) Instruction Set.

Boot perfor-

mance mode

Select boot type from Max Non-Turbo

Performance, Max Battery, or Turbo Per-

formance. Intel Turbo Boost Technology

provides the capability for the CPU to

overclock itself higher than its stated

clock speed if there is enough power to

do so. The Max Battery option contributes

to energy saving by dynamically adjusting

the power consumption.

EIST

Enable or disable the Intel SpeedStep

Technology. Intel SpeedStep Technology

is designed to save energy by adjusting

the CPU clock frequency up or down de-

pending on how busy the system is.

Turbo Mode The Turbo mode allows the processor to

run above its base operating frequency.

Enable or disable this feature here.

CPU C (C3/

C6/C7 report)

States

C3 and C6 are power saving halt and

sleep states that a CPU can enter when it

is not busy. If you are concerned about

performance (for all but latency-sensitive

single-threaded applications), and if you

have the option, disable anything related

to C states.
