Is one of my 980s fried?
I had 3 x 980 in SLI, everything was working fine, three-way SLI had been set up with control panel when I got the cards a few days ago. It was all dandy and 4k was looking great.
Then today (inconveniently during a heist mission on GTA V) the screen froze, the speakers emitted a continuous buzz and the system hung. When I restarted, NVIDIA CP told me that my "SLI configuration had changed" - when I looked, it was only showing two cards in SLI, worse still, device manager is only detecting 2 980s
I've narrowed it down to the offending card, I can confirm from testing with the 2 good cards that all the PCIe lanes are working fine.
...but the card that was in the lower slot (lane 3) won't be detected by windows regardless of which slot it goes in to, moreover if I try to run it as a single GPU in lane 1, I get no VGA output. The EVGA LEDs light up on the card when the system starts, although the fan only spins a couple of revolutions every 5-10 seconds or so.
Where do I start here? Inspecting the card, it looks fine, no visible damage, is there a chance is overheated and fried? Is there any DIY repair I can do or do I head straight to EVGA for the warranty returns process. FYI it's an EVGA 980 ACX 2.0.
All of the cards were running at stock with no OC.
Any help welcomed.Edited by 486DX - 5/24/15 at 10:03am
