My Maximus XI doesn't have adaptive mode, so I would like to use offset mode to lower the core voltage at idle. Now my system is stable with 1.3V, so if I understand this correctly, in order to lower the voltage for idle I need to set offest to "-" then input a voltage for step down. I'm going to use 0.2v but I will also need to raise the standard core voltage from 1.3 to 1.5. Is this correct?
