My Vega 64 (sapphire reference card) has suddenly seemed like it has stopped working and its driving me crazy. I can't play any game now for more than 20 minutes before the card crashes (flashes to black and the fans rev up to 100% and then the screens disconnect). It doesn't matter whether this is stock, turbo or a custom OC.
This also is happening on Heaven benchmark - it starts out getting 20-30 fps (1440p ultrawide mind you) and then crashes midway through a benchmark. Last month when I tested it I was averaging 85 fps stable on an overclock so I'm not sure what has happened here. Today while running Heaven, i noticed that the GPUTach power lights is stuck on P1 when running heaven (which is why the FPS is so low and why I assume its crashing). Going into wattman and changing the minimum state to P6 or P7 has all the lights light up immediately on the GPU and then when I run heaven, it just goes back to P1.
Anyone know what the issue is here? I updated the drivers (didn't work), then ran DDU and removed the drivers and reinstalled them from scratch and I'm still having issues.
I don't think the issue is the CPU (cinebench runs just fine and the PBO on my Ryzen 7 2700x overclocks to where it normally performs so I don't think that's the issue.
