[Values 21~22]

Disallows configuration for Turbo Mode.

Enhanced Intel SpeedStep Technology [Enabled]

Enhanced Intel® SpeedStep Technology (EIST) allows the system operation to dynamically

adjust processor voltage and cores frequency, which can result in decreased average power

consumption and decreased average heat production.

[Disabled]

The CPU runs at its default speed.

[Enabled]

The operating system controls the CPU speed.

Turbo Mode [Enabled]

 

This automatically allows processor cores to run faster than the base operating frequency if

it’s operating below power, current, and temperature specification limit.

[Disabled]

Disables this function.

[Enabled]

Allows processor cores to run faster than marked frequency in

CPU C1E [Auto]

specific condition.
