Need help Enabling SLI :(

[Mazon1x]

i have a 990fxa-ud5 r5 gigabyte board. and two evga gtx 570s ive tried everything possible. cant figure out how to enable these guys. Nvidia control panel only shows phys-x. both cards do show up and work fine. other than that.

They need to be in the correct slots, the ones marked pciex16. The others that say pciex4 will not work. Also do you have the sli bridge connected?

can you pm me a picture of what slots they need to be in. im almost positive they are in the correct spots. and yes sir/ma'am the bridge is connected

The slots are labeled, it's printed on the board.
