Posted September 13, 2014 Hi, I have two gtx 760's from gigabyte currently in my system. just a few days ago SLI was working great! just today I realized that I wasn't getting the option to enable SLI anymore. The bridge is on and both cards are working fine. Any ideas? thanks! (sneezes) "Sorry I'm allergic to bullshit" Link to comment Share on other sites More sharing options...

Posted September 13, 2014 Are your drivers up to date? Also try removing each card and running with only one. One of them could be dead. LTT's unofficial Windows activation expert. Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...

Posted September 13, 2014 Author Are your drivers up to date? Also try removing each card and running with only one. One of them could be dead. I do have the latest drivers, I even reinstalled them. I have not removed one card at a time yet because there both water cooled and it be kind of a pain. I just want to make sure that I exhaust all other options first. right before this problem started happening I switch my sound card from a PCi-e 1x to a pci-e 8x slot. do you think that could have done anything?

Posted September 13, 2014 Maybe one of your cards was DOA? -Nevermind- CPU: R5 5800X3D Motherboard - MSI X570 Gaming Plus RAM - 32GB Corsair DDR4 GPU - XFX 7900 XTX 4GB Case - NZXT H5 Flow (White) Storage - 2X 4TB Samsung 990 Pro PSU - Corsair RM100E Cooling - Corsair H100i Elite Capellix Keyboard Corsair K70 (Brown Switches) Mouse - Corsair Nightsword RGB Link to comment Share on other sites More sharing options...

Posted September 13, 2014 That happened to me on my last motherboard and I wasn't able to resolve it. I figured something happened to the motherboard for the GPU to not work properly in the PCI slot. Had to buy another motherboard :l Does your MOBO support SLI? He said that it was working fine before, so of course it does. Link to comment Share on other sites More sharing options...

Posted September 13, 2014 right before this problem started happening I switch my sound card from a PCi-e 1x to a pci-e 8x slot. do you think that could have done anything? Switch it back, maybe it's taking lanes from an x16 slot and not making SLI work. LTT's unofficial Windows activation expert. Link to comment Share on other sites More sharing options...

Posted September 13, 2014 Author Lol it was the sound card. somehow I guess the motherboard got confused between the sound card and gpu. strange.... Thanks for all the help!

Posted September 13, 2014 Lol it was the sound card. somehow I guess the motherboard got confused between the sound card and gpu. strange.... Thanks for all the help! Nvidia requires 8x to enable SLI, many motherboards share the lanes between the slots, chaging the sound card to a shared x8 slot could have made the other lane switch to x4, making SLI not possible. Remember Haswell CPUs only provide 20 PCIe lanes, if the motherboard has a PLX chip it can support more, so it doesn't matter if the board has 7 16x slots, the lanes are 20+a possible PLX chip.
