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, thus
allowing the transitions of P-state changing to occur 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 efciency. 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-dened 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.
CPU Flex Ratio Override (Available when supported by the CPU installed on the
motherboard)
Select enable to override the CPU Flex-Ratio setting, which is the minimum multiplier that
allows the computer to clock. The options are Enable and Disable.
CPU Core Flex Ratio (Available when supported by the CPU installed on the
motherboard and when "CPU Flex Ratio Override" is set to Enable)
Use this feature to congure the Core Ratio Multiplier settings for non-Turbo mode
processors. The default setting is 23.
Hardware PM (Power Management) 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 the 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.
Frequency Prioritization
RAPL Prioritization
Select Enable to prioritize RAPL (Running Average Power Limit) which sets the power
consumption limit for a processor to save energy. The options are Enable and Disable.
