CPU P State Control (Available when "Power Technology" is set to Custom)
SpeedStep (PStates)
EIST (Enhanced Intel SpeedStep Technology) allows the system to automatically adjust
processor voltage and core frequency in an effort to reduce power consumption and heat
dissipation. Refer to Intel’s website for detailed information. The options are Disa ble and
Enable .
Config (Configure) TDP (Available when SpeedStep is set to Enable)
Use this feature to set the appropriate TDP (Thermal Design Power) level for the system.
The TDP refers to the maximum amount of power allowed for running "real applications"
without triggering an overheating event. The options are Normal , Level 1, and Level 2.
EIST PSD Function (Available when SpeedStep is set to Enable)
Use this feature to configure the processor's P-State coordination settings. During a P-State,
the voltage and frequency of the processor will be reduced when it is in operation. This
makes the processor more energy efficient, resulting in further energy gains. The options
are HW_ALL , SW_ALL and SW_ANY.
Turbo Mode (Available when SpeedStep is set to Enable)
Select Enable for processor cores to run faster than the frequency specified by the
manufacturer. The options are Disable and Enable .
Hardware PM (Power Management) State Control Available when "Power
Technology" is set to Custom)
Hardware P-States
If this feature is set to Disable, hardware will choose a P-States setting for the system based
on an OS request. If this feature is set to Native Mode, hardware will choose a P-States
setting based on OS guidance. If this feature is set to Native Mode with No Legacy Support,
hardware will choose a P-States setting independently without OS guidance. The options
are Disable , Native Mode, Out of Band Mode, and Native Mode with No Legacy Support.
