ing SIMD Extensions (SSE) and AVX workloads. Each P1 ratio has the corresponding
AVX Impressed Current Cathodic Protection (ICCP) pre-grant license level, which refers
to the selection between different AVX ICCP transition levels. The options are Nominal,
Level 1, and Level 2.
SpeedStep (P-States)
Enhanced Intel SpeedStep Technology (EIST) allows the system to automatically adjust
processor voltage and core frequency in an effort to reduce power consumption and
heat dissipation. Please refer to Intel's website for detailed information. The options are
Disable and Enable.
EIST PSD Function (Available when "SpeedStep (P-States)" is set to Enable)
This feature reduces the latency that occurs when one P-state changes to another, thus
allowing the transitions to occur more frequently. This will allow for more demand-based
P-state switching to occur based on the real-time energy needs of applications so that
the power-to-performance balance can be optimized for energy efficiency. The options
are HW_ALL and SW_ALL.
Turbo Mode (Available when "SpeedStep (P-States)" is set to Enable)
Select Enable to allow the CPU to operate at the manufacturer-defined turbo speed by
increasing the 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 (Available when "Power Technology" is set

to Custom)
Hardware P-States
If this feature is set to Disable, system hardware will choose a P-state setting for the
system based on an OS request. If this feature is set to Native Mode, hardware will
choose a P-state setting based on the OS guidance. If this feature is set to Native Mode
with No Legacy Support, system hardware will choose a P-state setting independently
without OS guidance. The options are Disable, Native Mode, Out of Band Mode, and
Native Mode with No Legacy Support.
CPU C State Control (Available when "Power Technology" is set to

Custom)
Enable Monitor MWAIT
Select Enable to support Monitor and Mwait, which are two instructions in Streaming
SIMD Extension 3 (SSE3), to improve synchronization between multiple threads for CPU
performance enhancement. The options are Disable, Enable, and Auto.
