CPU P State Control
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. Please refer to Intel’s website for detailed information. The options are Disable
and
Enable .
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 .
