Now, after close to 2 days of use I just got Nvidia driver crashes and my monitors would go blank and I'd have to hard reset the system.
More or less the same symptoms that used to happen on the hero.
I have an extended replacement warranty on both cards but I really wanted to try and keep the 2 cards for the SLI performance. The only other thing I can think of is replacing the 860i Corsair PSU with the 1200i one, if this can actually be the reason this is happening. My other choice would be to go return those cards and settle for a single 780 Ti
Can anyone help with this? I am sure I am not the only running 780 Lightnings in SLI
Are you running them on stock clocks with stock voltage? If you are overvolting, and OCing, then your PSU could be tripping, but you would probably notice that if it were the case. Have you done a clean driver install with DDU? Is your Windows install clean and stable otherwise?
I had no issues running 780 Lightnings in SLI for the last two weeks, even with a slight OC on stock voltage it was fine. I have a mATX board, so it was hot, the top card got up to 82C. Everything was rock stable though. The rest of the system was using W8.1 / 4930k / x79 Rampage IV Gene / 16GB 2400 g.skill Trident / X750 PSU / HX850 PSU.
This past weekend I took one out to move into a different rig for dedicated folding, because well, one 780 is overpowered for what I typically do.
