when using pcie lane 2 with one card it works perfectly but when trying to use sli on lanes 1/4 i get no video through the cards only the onboard... any ideas?
device manager tells me there is no hardware installed for it. This leads me to believe the bios doesnt even see the card(s).
At first I installed them using an SLI bridge but then took one out to try and just install only 1... that works.
The cards spin up so I know its getting power.
CARDS... EVGA GTX560ti x2
And I know its not the card because I tried using both of them seperately.
MOTHERBOARD... GSROCK Z68 extreme 7 Gen3
Edit: also I have a 850watt power supply so thats not it either.
PLEASE HELP
