When I set a custom max voltage (undervolt) under GPU Tuning (advanced control) and reboot I constantly have to change it back by loading up my saved profile. Fan settings and frequency stay saved but my voltage constantly resets. Sometimes after a reboot it loads properly.
Troubleshooting steps already performed:
Is the Radeon Adrenalin 2020 20.1.4 settings crashing - If it does that that should reset your GPU profile to default settings. Turn on notifications it should tell you that it had to reset after a crash.
Are you certain you hit "apply" after modifying the voltage settings?
Many settings in the new GUI are not working properly - it might be that.
You can see some examples in this thread: https://community.amd.com/thread/246238
I do not see the notification of a crash. Frequency and fan settings stay saved after reboot. Voltage does not. I have tried defaulting settings and saving a new profile multiple times. I'll edit the post to reflect those troubleshooting steps. Again, I have the frequency and fan settings saving/loading properly after a reboot but the voltage gets reset frequently.
I solved the Problem in my case:
It was MSI Afterburner which applied ist own settings after reboot. Make sure your afterburner (if youre using it) won't affect the voltage Settings AND make sure its not applying the settings on system boot (the Windows Icon on the Right side of the ASI Afterburner Main Window has to be disabled!).
That fixed it for me
Thanks for the updated reply on the solution you found. Unfortunately I do not use Afterburner and never installed it with my 5700. I’m glad you got it figured out though. I still have issues with it resetting on occasion even with all the latest drivers. Hope it stays fixed.
Many third party OC tools like MSI Afterburner, older versions of Sapphire Trixx that used to support GPU Overclocing, and Asus GPU Tweak II will often cause changes to GPU SCLK/MCLK, fan curves, GPU voltages at boot and override the default Adrenalin 2019 or 2020 Driver settings.
Asus GPU Tweak II can do things like apply overclocks at boot, even if you set the option to turn it off and apply thst change before previous power down.
In some cases, depending on the OC tool version versus AMD GPU Driver version they simply conflict with each other.
Third Party OC Tools like Asus GPUTweak II are promoted by ASUS for use with ASUS RX5700XT and AMD Adrenalin 2020 drivers.
Third Party OC tool conflicts like this should not happen and should be reported as a Bug to AMD and the Third party OC Tool manufacturer such MSI, ASUS etc.
The only tool I have installed is Trixx. Running latest version though and still recently had the voltage reset on me. I’ll try uninstalling it and test if that helps. Appreciate the updated response.
Same issue on Sapphire 5700XT Nitro+. On previous Adrenalin 19.11 all was ok, after updating to 20.4 voltage curve will be dropped after shutdown, but fan curve and power limit is ok.
I'm not using trixx or any other such software - only wattman. After some observation I can say that problem not always occurs. Fast boot is disabled, notifications is enabled - no failures, 2 GHz on 1.07 V - no issues in games
