19.12.3 has been stable for me since I used MSI A/B to Erase autosaved startup settings.
Now my OC in wattman actually stick and don't reset on every reboot.
No more random blackscreen Wattman OC resets. Were the screen goes black and my OC in wattman is reset to default.
And I see higher frame rates in general. I don't know what else MSI A/B is doing but I also notice that PowerLimit slider actually works now. I had no idea it wasn't working for me before. I now only use 10% instead of 40% as 40% causes too much heat with very little difference in clock rate.
As of right now both wattman and MSI A/B works great! Once I exit out of MSI A/B and start up wattman, wattman takes full control of fan curve (that I manually set from before). Clock rates are right, etc. No more issues. No more fan speed stuck on what I set in MSI A/B in wattman. I saw this after rebooting PC after using wattman for an hour or so.
