I just upgraded from 470SLI to a 970SC. I also upgraded to a Samsung 28" 4K monitor. I did a fresh install of everything after reformatting my HHD. I was in 4K heaven for 4 days playing WoW on ultra settings . Yesterday I started to get BSOD & freeze ups. I tried several things, but the winning combo seems to be lowering my resolution to 1440, lowering my settings from ultra to high, using Precision to add a little more juice (12mV) & changing my fan curve so that it ramps up significantly after 65c. I was able to play a few hours tonight without crashes. I hope to go back to 4K tomorrow & ramp back up to ultra settings again. I haven't loaded Guild Wars 2 yet, but I imagine it's even tougher on my VGA than WoW.
Should I be having this problem? Am I expecting too much from this card? Is my voltage solution okay for a year or two? Is getting another card for SLI going to be my best solution for 4K gaming in the long run? I was hoping to get by with this single card until at least the next generation is released.
