Use GPUz to look at your ASIC quality. It's a general guide to how much voltage is needed to OC. Not all samples are the same, and it of course depends on how high you're going. My MSI 980 is at 1503MHz core and 3800MHz memory (which is a pretty good OC) and I'm running with a MAX voltage of 1.281V, but in reality I don't see it go that high - no need to even cross past 1.3V. (I did up the min-voltage at some clock steps since I was seeing some instability when closing steam, for some reason.)

Out of the box just put power slider to Max and set it to "heat" priority. Then cranked the fan to 100% core/mem @ 300 both and ran Firestrike. Highest I saw the volts hit was 1.21. Temps stayed in the 60c range. Clocks hit 1503 at peak but averaged i'd say 1483 (ballpark).
I can't get over +300 on the core stable and I've yet to try more than +20mv to see where I could. So I just left it at that. I've yet to try higher on the mom. I don't even know my ASIC score. Might as well check it now...
