Intel SpeedStep
Allows you to enable or disable the Intel SpeedStep mode of
the processor.
The Enable Intel SpeedStep option is enabled by default. If
the option is disabled, it places the processor into the highest
performance state and prevents the Intel SpeedStep applet or
native operating system driver from adjusting the processor's
performance. If the option is enabled, it allows the Intel
SpeedStep-enabled CPU to operate in multiple performance
states.
C-States Control
Allows you to enable or disable the additional processor sleep
states. The operating system may optionally use these for
additional power savings when idle.
The C states option is enabled by default.
Intel TurboBoost
Allows you to enable or disable the Intel TurboBoost mode of
the processor.
The Enable Intel TurboBoost option is enabled by default. If
the option is disabled, it does not allow the TurboBoost driver
to increase the performance state of the processor above the
standard performance. If the option is enabled, it allows the
Intel TurboBoost driver to increase the performance of the
CPU/graphics processor.
