I'm betting it's the SLI bridge. While more power may be needed, 850W shouldn't cause that much of a problem.
check if one card alone runs well on each PCI-E slot and then if that is so, it very well maybe the connector- if you are in Atlanta, I got a bunch extra
Well guys, it looks like the new card is the problem after all. I pulled my old one out and tested the new one for a few days, at first everything looked OK and then... Crash! Random reboots and freezing. I tried a different SLI bridge, and I think that we can agree now that my PSU also isn't the problem. It just took a little longer for the new card to behave this way on it's own. Sorry to bother you guys for nothing :/
I've read a lot of ppl with troubles with the 2x gtx 690 sli escalation but didnt find any solution jet Please help! How did u solve your problems with ur 2 x gtx 690 quadsli scalation problems? my email es cmgver[at]gmail My quadsli doesnt work with many games, i have drastically drops of FPS from 130 to 10 in games like battlefield 4 and i cannot use sorround 3 screens in many games too. I discover by accident that when i use no SLI configuration then it works better with no FPS drops, so is not the RAM or CPU. I bought the two gtx 690 for 3 screen sorround rig, in that moment i had three 27' cinemadisplays but the performance was horrible, i thought it was not possible, but now i have only one screen and the same problems persist :/ My rig is: 2x gtx 690 mb asus rampage IV extreme cpu 3930k 4 x 4 gb Tridentx G Skill 2 x 128 gb ocz vertex 3 RAID 0 1 x 4 tb western digital caviar black monitor Asus swift PG278Q with g-sync windows 8.1 64 bits bios firmware in my 690s are: 80.04.1E.00.90 80.04.1E.00.91 i updated the ASUS RAMPAGE IV EXTREME to the latest bios firmware 4901 Thanks a lot! and i will appreciate any clue of how to solve my problem.
