Well ive tried both stock and OC and it still happens. It is pretty rare like every few minutes, but it happens, and not in every game. And in some games, i also get occassional stutter when moving fast/loading area[like in far cry 5, and its not autosave!], im sure its not overloading VRAM, since ive monitored vram and it doesnt even get close to full capacity[like using 3-4 gb only]. Im using game on NVME SSD, 16gb of ram with 3600mhz and cl17, and ryzen 3600 so theoretically there should be no problems whatsoever. PSU is corsair rmx 850 so its pretty much overkill.
