I have tested to set 0x80 to all the ucCKSVOffsetandDisable values and it isn't disabling avfs. It is only increasing voltages, but the 25mv margin is present. I forget that DPM 0 is using manual voltages as is the only maual setted voltage at the bios, so it can't be using avfs mode.
Wattman auto values are ok, manual ones are the ones that are wrong, as they are needed to be changed becuase are using higher voltages at dpm 3 or 4 than at dpm 7.
Also all the tools like Afterburner, Trixx, ONT, WattTool, AMD memory tweak, are wrongly using manual voltages as default as you can see in at the my video at here: https://www.overclock.net/forum/27868488-post5211.html
so I was having proglems with them cause with the manua 1.15v my gpu is not stable.
I don't see a GUI need, I don't see the need to change asic profiling sigma, etc values.
Is just set the clocks you want in auto mode or at bios, then if your voltage is to low or hight you could change it with a software voltage offset or increasing usMaxVoltage_0_25mv. Also you can adjust dpm voltages and the 25mv avfs voltage margin with CKSVOffsetandDisable values. Try to tweak these values to see how they are working, and forget the rest of asic profiling and the 80 to ucCKSVOffsetandDisable.
If you don't see the VID voltage at hwinfo, you can see it with WattTool.
I see no way to disable avfs into the bios. But if you want only manual voltages, I see the that the easy way is to set a OverdriveNTool profile with the clocks and voltage that you want, and applying it at windows start with windows tasks scheduled adding a task with ONT and a command with the profile name: -p0"name". But you will lost the 25mv avfs marging. Edited:
maybe you could easily use an afterburner manual profile and applying it at startup, but I don't have tested this.
Also you could test this (I don't have tested it jet): https://forums.guru3d.com/threads/ov...7#post-5691915
With an Afterburner sortcut adding /wr258,26B you can Disable Avfs, with /wr258,26A you can Enable Avfs. So Changing 6528X voltages into bios and applying it at windows start with windows tasks scheduled adding a task with Afterburner and the Disable Avfs command.
