VDDCR CPU Power Duty Control
This item allows you to set the duty cycle of each VRM phase based upon current and/
or temperature.
[T.Probe] Sets the buck controller to balance VRM FET temperatures.
[Extreme] Sets the buck controller to balance per phase current.
DO NOT remove the thermal module. The thermal conditions should be monitored.
