Got my EVGA GTX 680 signature+ today and get it installed, so I figured I'd play around with overclocking it, but first I wanted to give it a run through Heaven at stock settings. Crashed in about a minute, wtf? Just out of curiosity I bumped up the power to +130% (highest it would allow, my Galaxy I had before allowed up to 132%) and bumped the core up +30, and as I expected, Heaven hard locked almost immediately. I'm using the newest beta drivers from nvidia, since displayport didn't work with my monitor on prior drivers. My overclocks on my Galaxy GTX 680 weren't spectacular either, I could only get +75 on the core before it would crash Heaven as well. At least it worked though.
I tried the other 8+8 pin power lead off my PSU, just to make sure that wasn't an issue, and it wasn't. Monitored my voltages and they appear to be within spec, no drastic fluctuations. I was running two 6970's on there before, so power shouldn't be an issue. Case is open and it's nice and cool in here, so heat isn't the problem. Before I send this thing back, does anyone know if there are any issues with Heaven or some setting somewhere I need to change? I seem to remember reading a post about having to turn off some setting in NVCP or something like that, but I don't really remember now.
