Hmm. So guys, any guess what the problem is here?
I ran up to 720/linked/1096 in Quad SLI, with the CPU at 4.4, and I got
this. (P35999.)
Individually the cards perform like they should, but going off the vantage thread I should be at more like 40,000 for those clocks. It's only in Quad SLI that I'm missing 4k points.
(Side note: this bstock card is doing really well on air, 1087mV and it was up to 720. I haven't tried higher yet, max load has been 75C.)
