GTX 1080 Problem

[XCalinX]

Hey guys,

I have 2 GTX 1080s in SLI right now, but I'm facing a problem with them. So I turned on my PC this morning and noticed that it was set to 1024x768 in Windows and that when I right click on my desktop the nVidia CP option is gone. I went into device manager and saw that my 1080s have the little yellow troubleshooting icon next to them. See this. Then I went to the nVidia site and downloaded the latest driver (I was running an older version), instelled it, restarted my PC but the problem still persists. I set the resolution back to 4K in Windows but it feels very laggy. I tried disabling and enabling them in Device Manager but it didn't do much.

Any ideas on fixing this? Thanks.

Take a look in the NVIDIA control panel instead, see if there is anything there

Did you read the first post? It says that I can't get into it anymore.

use DDU to completely uninstall the drivers and double check that you are indeed downloading the correct driver.  If it still isn't working then I would remove both gpu and try them individually to see if there is a problem with one of them.

Yeah I removed the driver with DDU and it works now, but I can't enable SLI now. The option to turn on SLI isn't in the CP anymore even though both cards are recognized.

And no, it's not automatically turned on, I get the same performance I was getting before I upgraded to SLI.

Update. I found out in GPU-z that one of the 1080s is running at PCIe x2 instead of x8, and nVidia only supports SLI with x8 slots. I don't know why though.

dont know why it supports it only at x8 or why your slot is x2

Full system specs?

See the sig. Also, like I said, it works now but one of the GPUs only runs in PCIe x2, making SLI not possible,

Have you tried switching the positions of the Graphic Cards to test if it's the PCIe Slot or the Graphics Card itself?

Not yet, because I have a custom loop so it's not that easy but I will drain it later and try it

I have run into this before. Uninstall the drivers and reboot the computer with only one graphics card, completely remove the second 1080 from the PCIe slot. If you don't do that, this will not work. Then install the drivers from nVidia. Shut down and put in the second card. Windows will take a while to boot up and installs drivers again on its own, let it do that. Then you can go to nVidia control panel and the option to SLI will be there. 

 

I know this makes no sense, but it works.

i found out my 1080 was only running in x2, it wasnt sat in the pcie slot properly because of an obstruction, just see if yours is seated properly.

Well guys, I fixed it. It was a weird fix but who cares as long as it works? I updated my board to the latest beta BIOS and it works now. Now to see if I can OC my 1800x farther with this BIOS
