multitude of logical processors. This
technology allows the operating system to
get more out of the internal processor
resources, which in turns leads to
increased performance.
Information:
This setting should only be disabled
when using an operating system older

procedure.
Intel(R) C-STATE
tech This setting allows the operating system
to set processor clock rates on its own,
thereby saving energy. Enabled Enables this function.
The processors are run at different frequencies,
thereby saving energy.
Disabled Disables this function.
Both processors are run at the same frequency.
