I had the unfortunate experience of losing many hours of rendering time in Topaz VEAI when my PC crashed and restarted. If anyone else is struggling with random crashes, maybe check that your RAM is stable. Try something like Passmark Memtest86.
XMP / DOCP is supposed to be a stable memory overclock right out the box, that’s why manufacturers are allowed to market the kits with the overclocked speed written all over the box, not their JEDEC speed.
One of my computers is completely stable with overclocked ram, my other machine is not, they’re both from G.Skill by the way. The unstable machine is stable in most scenarios with DOCP enabled, but Topaz is more taxing perhaps.
