This puts some limitations on lower P-State downclocking/downvolting O You cannot set frequencies and voltages below the minimum (which is rather strict and very close to default). O Unlike the frequencies, you can independently adjust voltages for all 3 points So if you try to adjust frequency for the middle point, it will be corrected according to interpolation rule mentioned above right after applying new settings Middle point frequency cannot be adjusted independently, frequencies are always linearly interpolated from the first point to the last point. O You can adjust the frequency independently for the first and the last point only. So the curve will be corrected according to the following limitations when you apply it: Voltage/frequency editor is allowing you to adjust frequencies and voltages independently for all 3 V/F curve points (or 3 P-States), however AMD driver and RVII architecture put some restrictions on the curve editing approach. So it is no longer adjustable in AMD driver and supposed to be locked now. It is gone with Adrenalin 2019 drivers family when fan curve adjustment approach was introduced by AMD. Temperature limit slider is also supposed to be locked by design on RVII, it was a part of old AMD fan control algorithm. So simply open the editor (either press VF editor button in the skin next to core clock slider or hit + keyboard shortcut to open the editor and you’ll be able to adjust voltage there). On RVII series cards AMD driver allows up to 1.2V overvoltage (from default 1V) and voltage control is provided in MSI AB at voltage/frequency curve editor level.

On the previous AMD GPUs the slider provided direct voltage control mode implemented via low-level access to SMC or voltage controller (slider position defined either full target voltage override or P-State independent voltage offset) and such voltage adjustment form was required because native AMD driver’s voltage adjustment range was too low. Core voltage slider in MSI AB is supposed to be locked on RVII, that’s normal and by design.
