Holy Moly. This is my first trigger pulled on a current gen video card. I am upgrading from a hand me down GTX 280, and that was a replacement last year for a 4830. SOo... after scanning this thread I just randomly downloaded MSI afterburner and overclocked until it felt like it couldn't. Weirdly, I set the Memory to +200 but it seems to cap out at +101 on GPUZ? Not sure why there possibly because of DDR? I have no idea, I'll post pics. I was able to get +122 Core, +202 (shows as 100?) Mem.
Fan speed never went over 48% on MSI Kombuster stress.. Temp never went over 71 degrees, my old card would hit 90 degrees on stock settings playing Skyrim. This thing is an absolute Beast.
I actually held off on clocking it any further until I had some responses to this cuz I really have no idea what i am doing. As far as I can tell, I've had absolutely no artifacts or errors.. it still runs cool as dirt, and my temps never got high at all. What a beast.
