Rig: Windows 10 Home OS
GTX 780 6GB x 2
Z77 Sabertooth-Asus Motherboard
I7 3770K CPU
SSD 240 GB
HDD 2 TB
16 GB of RAM Ripjaws
1000W Corsair PSU
*No mods hardware and software side*
This is what I've done so far to troubleshoot SLI issues. I have played with both cards games and they work identical in performance. My PC also reads both cards are there ready for use as I can have one running a game and dedicate the other as a PhysX card. I've also set my lanes in the BIOS to PCI-E x8x8. They are in the right PCI-E ports and yet when I put a SLI bridge on, no communication and no ability to select "Maximize 3D Performance" in Nvidia's UI. I've reinstalled drivers over and over again doing the proper procedure and yet no success. I've tried three different ribbon SLI bridges and flipped them on different connectors and no luck. Can this be bad connectors? Bad software on one GPU? Or bad luck with ribbon SLI bridges? Any help would be appreciated!
