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.

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 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.
