Hi, I recently upgraded to a new cpu and motherboard and reused my rx580. The default max boost and voltage is 1366mhz at 1150mV. I run an undervolt profile to keep it quiet where the max boost uses 1065mv and this has worked fine for a year and works fine now.
However, when I start my system or wake from sleep, in game the card now uses 1.2v instead of 1.065 or even 1.150v. It still lists the proper values in radeon settings. I have to go into radeon settings and make a manual change and apply it before it goes back to 1.065, then all is fine until I reboot.
Is there a setting I've changed somewhere that makes it overvolt like this? It is too loud to run at this level.
