I've been told by someone here, I forget who.. but they said 4ghz on an evga 780i ftw is near impossible. I'm currently rock stable at 3.6 , prime can run all night while I'm at work, that was on air. Temps would get HIGH but it would never fault and stop.. even after 9 hours. Now I'm running it on water and so far SMALL FTTS for 2:45 mins and temps are 57c... this is at 450x8.5 for 3825mhz... 1.3 vcore.. drops to 1.28o when Im idling.. Is the extra vcore boost to try and reach 4ghz even worth it? Should I just be happy with where it's at now or should I go for 4ghz? I hear 1.3v on 45nm isnt good for loads for longer periods of time.
