Hello! I just finished building a new custom PC. Everything worked fine with 1 GTX 690. But when I put the 2nd card in it would show the mobo screen when I turned it on. Then just a black screen. I plugged them into PCIex16-1 and 2 slots. I have tried 2 different bridges and flipped them both ways. Both cards work on there own. Here are my PC specs.
Gigabyte GA 990 FXA UD7 mobo
Dual Nvidia Geforce GTX 690 ASUS bid cards
AMD FX 8350 Vishera CPU
32gigs ripjaw gskill x ram
Cooler master silent gold pro 1200w psu
Kingston hyper x 250gig SSD
Thanks for the help!
Also I have tried every power cable variation. And tried every configuration for each card alone in every slot. My mobo does support sli. I just can't seem to get it to work with both cards in.
Is it possible I'm not plugging them into the right set of PCIe slots?
