I had wattman crash on my gpu and couldn't find any solution. There is no way to play any game. For detect the problem, I was monitoring gpu stats and then I see vram stuck at 200mhz and it never boost up. For solution what I've tried;
-Latest Driver, ex. whql driver, ddu driver and fresh setup
-Format (Windows 10)
-Tried increase mhz manually with afterburner
-Different video output, different cable
Unfortunately any above solution doesn't work on my gpu. I saw in rx 4xx, 5xx models, in radeon experience app possible to adjust vram mhz bars manually but for 5700xt that feature isn't exist.
