Ok my gpus were OC'd to 700/1400/1000 and they were running just fine untill today... Crysis randomly starts flipping out and then i see my desktop. I ran crysis without a problem for 2 hours with those speeds. I also tested in furmark for 15 mins (had to go to the doctors and i dont want to have a stability test running when im gone especially since i had burntest checked.) temps seemed to peek at 68c and didnt get higher than 63c during crysis. I tightened my mem timings to 4-4-4-12 2T and it is OC'd to 847Mhz. could the timings/ Mem OC be causing this?
