[out] Frequency

Clock frequency of the requested engine, represented in hertz.

[out] MaxFrequency

The max frequency the engine can normally reach in hertz while not overclocked.

[out] MaxFrequencyOC

The max frequency the engine can reach with it's current overclock in hertz.

[out] Voltage

Voltage of the requested engine, represented in milli volts.

[out] VoltageMax

The max voltage of the engine in milli volts while not overclocked.

[out] VoltageMaxOC

The max voltage of the engine while overclocked in milli volts.

[out] MaxTransitionLatency

The max transition latency to change the frequency, in 100 nanoseconds.
