SLi not working?

[Kohta]

Maybe I can get some advice, I have never really tried dual Nvidia GPUs but it's come time to try... and it isn't working.

This is my wife's setup:
ASUS Crosshair IV Forumula
AMD Phenom x6 1090T
16GB RipJaw 1600mhz RAM
Dual - GTX 560 ti 448 Core Classified
Corsair TX 850W
Windows 10 Pro

I have moved them around slots, from the first, second, third etc and whatever else for orientation and it only lets me select which one I want to render PhysX on. They are linked with a SLi bridge.

These cards are currently situated in first PCIE X16/X8_1 and PCIE x16/X8_3 lanes.

That motherboard doesn't have an sli signature, so you cant sli on that motherboard. Sorry.

Edit : don't fret tho. There's probably a hack for it. Search around....

+1 ^^.

If you take a look at their website, you don't see any mention of SLI support: https://www.asus.com/us/ROG-Republic-Of-Gamers/CROSSHAIR_IV_FORMULA/
