Hi, i've a problem to make sli with two Asus GTX 680 video cards on my AsRock Fatal1ty 990 FX Killer.
When i plug the two cards and connect the SLI bridge, I've no options into the nvidia control panel about activate SLI.

BUT, when I reboot and disconnect the SLI Bridge, the SLI option appear into the NVIDIA Control Panel. And it say : "please connect a SLI bridge for use SLI"

I've tested 3 different bridges, re-install windows, testing a lot of different drivers (using DDU for cleaning olds drivers) etc...

Please help me, I lose my hair ^^

Thank all :)
