I have an rx 550 4gb running in a system with a 520 watt corsair psu and an rx 570 4gb running in a system with a 600 watt psi. They both crash to a fuzzy static screen under stress, and don't get as high of frame rates as they should. My rx 570 did have good frames for a time but after a 15 minute 15% overclock test ending in a crash it now has this very same problem, all temps are fine always please help me out here I can't find anything on this error
