CPU P State Control (Available when "Power Technology" is set
to Custom)
SpeedStep (P-States)
EIST (Enhanced Intel SpeedStep Technology) allows the system to automatically adjust
processor voltage and core frequency to reduce power consumption and heat dissipation.
Please refer to Intel’s website for detailed information. The options are Disable and
Enable
.
AVX P1 (Not available when "SpeedStep (P-states)" is set to Disable)
Select Normal for the Intel® Advanced Vector Extensions (Intel® AVX) feature to operate
normally, which will provide a set of instructions for doing Single Instruction Multiple Data
(SIMD) operations in Intel processors by adding MMX and SSE support. The options are
Normal,
Level 1, and Level 2.
Activate SST-BF (Speed Select Technology-Base Frequency)
Select Enable for Intel Speed Select Technology-Base Frequency support. The options are
Disable
and Enable.
Configure SST-BF (Available when Activate SST-BF is set to Enable)
When this feature is set to Enable, the system BIOS will configure SST-BF High Priority
Core settings so that system software does not have to configure these settings. The
options are Disable and
Enable
.
EIST (Enhanced Intel SpeedStep Technology) PSD Function (Available when
"SpeedStep" is set to Enable)
This feature reduces the latency that occurs when one P-state changes to another, which
will allow P-state to change more frequently. This will permit more demand-based P-state
changing or switching to occur more frequently based on the real-time energy needs of
the applications so that the power-vs-performance balance can be optimized for energy
efficiency. The options are
HW_ALL
and SW_ALL.
Turbo Mode (Available when "SpeedStep" is set to Enable)
Select Enable to allow the CPU to operate at the manufacturer-defined turbo speed by
increasing CPU clock frequency. This feature is available when it is supported by the
processors used in the system. The options are Disable and
Enable
.
Hardware PM State Control
Hardware P-States
This feature allows the user to select between OS and hardware-controlled P-states.
Selecting Native Mode allows the OS to choose a P-state. Selecting Out of Band Mode
allows the hardware to autonomously choose a P-state without OS guidance. Selecting
Native Mode with No Legacy Support functions as Native Mode with no support for older
