I apologize for this question, but what voltage did you see in Afterburner before you adjusted it? The reason why I want to know is because mine started at 1.100V, and I have a feeling that this is way off.

But OCCT itself says this about the Shader Complexity: "The highest value is not always the best."
I don't know what this means exactly
, however it seems to me that using 8 has the potential to be pointless.
I would run OCCT myself right now, but I'm in the middle of a run of EVGA OC Scanner (61 minutes and counting with no artifacts).
I spoke too soon: I got 5 artifacts at 62 minutes.
