Datasheet
Once a target frequency/bus ratio is resolved, the processor core will transition to the
new target automatically.
new target automatically.
On an upward operating point transition, the voltage transition precedes the
frequency transition.
frequency transition.
On a downward transition, the frequency transition precedes the voltage transition.
When transitioning to a target core operating voltage, a new VID code to the voltage
regulator is issued. The voltage regulator must support dynamic VID steps to support
this method.

During the voltage change:
It will be necessary to transition through multiple VID steps to reach the target
operating voltage.

Each step is 12.5 mV for Intel MVP-6.5 compliant VRs.
The processor continues to execute instructions. However, the processor will halt
instruction execution for frequency transitions.
