Currently have it set to +60/+400 which is an effective 1262/1702 and it's giving me some trouble in Heaven but runs just fine in Kombustor. The issue isn't that the Nvidia driver is crashing/recovering its that Heaven itself is crashing. Are heaven crashes normal? It seems that my card is a poor OC. (GPUz shows a boost of 1236 but the graphs of GPUz and Afterburner both show 1262 if that means anything)
This just occurred to me...How do I tell which BIOS it is currently set to? The +60 with an effective 1262 indicates the LN2 if I'm not mistaken but I haven't changed it...Does that mean I got a return/refurb from Newegg or is it possible to ship with the LN2 enabled?
Also, is it necessary to adjust the fan profile for an OC? I have it set on 100% while I'm testing but is it okay to leave it on auto once I've found my spot?
Crashes are normal as well as having to hard reset. Kombuster isn't really the best test for stability, I'd use it for temps, but that's about it. And use the graphs in Afterburner for your max clocks, not GPU-Z. When looking at your card in the computer, the LN2 BIOS is to the right, so you're probably using it since the default core speed for it is 1202mhz. 100% fan speed will let you squeeze out a few more mhz for a bench, but unless you want it running that loud during a game, you probably won't be stable unless you lower the overclock a few mhz.
