CPU VCore 7 Shift allows more voltage to
be added to the default voltage settings. A rule of thumb, never try
anything beyond 1.6v (after adding in the 7 shift voltage). For example, I
set vcore to 1.4v and Vcore 7Shift to 1.15%, the final voltage is 1.6v for
vcore.
That is to say, if you apply 1.55v for
Vcore and +1.35% for your 7-Shift, you will be getting 2.0925v.
Final CPU Voltage = Vcore X 7-Shift.
