I mean the open-gl test. I've used it enough to know about where it should be for certain speeds, but if for some reason it drops to 4100 or 4200, its generally the nb needing voltage assuming your memory is rock stable. My best multicore is 9800 something, I think I did that at 11.5x267. I ran into a few problems so I dropped back to 265htt to figure stuff out.
