Last week I had a thread running about crashing to black screen/no DVI, but after thoroughly testing both cards individually in both slots and not coming across any issues, I put them back into SLI.
The system ran fine after this for 5 days of basic Windows stuff and gaming(Civ 5, AC4). Last night, the whole issue started up again.
When I got the black screen this time and rebooted, I took the DVI cable and moved it to the DVI-D port, which gave me a message I have never seen before basically stating "power down the system, connect power cables to the card and reboot. So now I'm thinking there is a power issue going on?
But until last night, the original crash issue always happened when SLI was on. Now it can crash with SLI off, but the interesting thing was that I was connected to the top card when I got that power message, yet, I just did a test with the top card's power cables untouched, BUT the bottom card's power cables removed. Also, removed the SLI bridge. Booted up and the system has been stable for a good hour.
Now since I tested both cards individually using both sets of power cables, both PCIe slots, can I safely assume this is either a bad SLI Bridge or a bad power supply starting to fail. I mean it's a Corsair 1200w from 3 years ago when I had dual 580's, but perhaps it's dying? I mean 1200w should provide enough overhead for my system, right? Any thoughts are welcome.....
***also, how much does it matter that in the EVGA Precision app, card #1 shows a millivolt of 887 while card #2 show 861mv.
