Recently built one of these because I wanted to play around with it. So far i'm impressed. But it seems to achieve 1085mhz on the gpu (7660d) I have to push it all the way to 1.375v. Maybe slightly less but it crashed at 1.35v. I have a big zalman optima 120mm HDT heatsink on there so temps are fine. I"m just wondering how far this thing should be taken. In fact, I don't even know what the default voltage is since in my bios it just says "auto". Anyone got any ideas here? Again, it seems stable at 1.375v @ 1085mhz with some 1600mhz ram, but I dont want to kill this thing by running furmark overnight.
