after days with no crashing I can confidently say that this solved the issue. Why? I genuinely have no idea. I was fully utilizing the increased vram clock speed in stress tests, but in games it would crash. Maybe there's some other weird thing in the most updated VBIOS for my card that was causing the crash
Either way, Going from the L12 to the L10 VBIOS Asrock 5600xt Phantom Gaming solved the crashing.
