IDK why but I get a lot more artifacts on this scene than any other in the heaven benchmark
I was only able to get to 190MHz with no artifacts.
As for memory.. I'm not sure how to figure out how high to go.
One review said this, "Our GTX 1080’s GDDR5X memory also took a final offset +400MHz to achieve a 5400MHz final stable memory clock. We noticed that there is a memory hole with instability around +500MHz offset, and that we could then push it even higher to +600MHz, but we lost some performance compared with a +400MHz offset."
I'm not sure how they found it it had a memory hole? Or that they lost performance? I'm guessing FPS?
they got to +230 with no issues somehow
