Doesn't seem like anyone is getting any questions answered anymore but I'll try anyway.
I want to run 3x gtx 580s on 8x/8x/4x Z77 board with Ivy bridge CPU. Ofc, it only detects 2 gpus and forces the 3rd to be physx. I run it on Win 7 64 bit.
I got it to run 3 way SLI, but instead of getting an increase in performance, I got a MASSIVE decrease.... 20 fps in games that I normally get about 100fps in. What's going on here? I looked at my pci busses and for some reason one of them is listing as pci e 2.0 x1 instead of x4. How do I force them all to run proper? Need some help.![Frown :( :(](https://tpucdn.com/forums/data/assets/smilies/frown-v1.gif)
