SLI NOT working...

ChrisVohho · Jan 8, 2017

So, I built my PC about a year ago and I just recently bought a second card for my setup to utilize SLI. The trouble started when I pulled up the Nividia Control Panel to enable it, the only problem was that it wasn't giving me any of the SLI options (Maximize 3D Performance, Disable SLI) It did however show both cards working. So, I tried a few quick fixes like reinstalling the drivers, checking the bios for updates, double checking that the cards are in the correct PCI slots, and trying each card individually. Nothing seemed to fix it. I figured maybe the SLI bridge was bad so I tried 2 new ones and neither one showed a difference. So I took it in to my local computer repair shop, they checked it out over a few hours only to tell me that they had contacted Nividia and received some sort of patch that didn't fix the problem. He also retried some of the other solutions I already had done and checked the "GPU SLI connectors" (Not sure if that's the correct term for it) and said they were fine. Nividia told him that it was just a simple glitch and that just because it's wasn't showing up didn't mean it's not working. Although, while using GPU-Z I also noticed that under SLI it also stated "Disabled". So, I installed MSI Afterburner and checked the usage for both cards in game and got 100% from the 1st card and 0% from the 2nd. I'm still fairly new to PC gaming so I'm sorry if I've left out anything. Could someone please help me find a solution to fixing this?

do you have any displays connected to the second GPU? Do you have another SLI bridge to test?

I do not have any other displays connected to the second GPU, I have 1 monitor (Asus ROG PG27AQ) plugged into the first GPU through display port. I've bought and tested 3 SLI Bridges so far, each new. I don't have anymore as of right now, only the 3.

Mussels · Jan 8, 2017

that is a little confusing, as far as i can tell everythins is done correctly.

all i can advise here is updating the BIOS on the motherboard and video cards, and doing a clean install of the drivers.

Any other items using PCI lanes?

I've actually already checked the BIOS to ensure I was using the latest version, I reinstalled drivers as well. Only the 2 GPU's are in my PCI lanes.

This is the only thing I can suggest atm.

I would run DDU after uninstalling your drivers the normal way via the control panel. http://www.guru3d.com/files-details/display-driver-uninstaller-download.html

It's very possible there's some profiles that weren't deleted after the reinstall. This should take care of that.

Sorry it took me awhile to get back, but I managed to do as you said. (Uninstalling the drivers via the control panel and then running DDU) It still did not work. It was definitely worth a shot though!

Different video output?

Mussels · Jan 8, 2017

i saw gsync options - disable SLI and see if SLI shows up?

google showed me that SLI + DSR + Gsync, only two of these can be active at a time. Older thread, but definitely try disablingh Gsync, trying a non Gsync monitor/TV, and disabling DSR.

I think DSR is the main issue with SLI.

I just tried two different monitors. One of them I used DVI instead of a display port. (Neither uses G-sync) I actually already had DSR off so I just turned off G-sync to try it on my current monitor. I even restarted my PC to see if SLI would eventually appear but nothing happened.

Toothless · Jan 8, 2017

Turn off all those extra features, and I'ma check my SLI goodness.

EDIT: My SLI is off because The Division has some serious issues but it checks out just fine.

zo0lykas · Jan 8, 2017

on device manager do you see both cards ?

try swap cards, botton one on top, and top one set in bottom.
and another question you sure connect right POWER cable ? cuz i so 12v cable should go motherboard 4pin and peoples use that for gpu, make sure you connect right.

double check or all power cables connected right

SnakeDoctor · Jan 8, 2017

What about the SLI switch on the motherboard ? Just went through the manual first time seeing this.

Check what light status yours is on aswell.

'set up g sync' is showing, so somethings weird if you dont have a gsync monitor

Beat me to it

Also, according to the manual, the second card could be in PCI-e x16_4 when using a 28 lane CPU like the 5820k. From the picture it looks like it is currently in PCI-e x16_2.

The switch doesn't actually do anything, it just lights up LEDs next to the correct slots to tell you which slots to use.

Ascalaphus · Jan 8, 2017

You need to change to a different pci-e slot from where your second GPU is sitting. It is currently set at x4 and you cant change that. It won't work with the 28 lane 5820k as Nvidia states that x8 is the minimum in order to achieve SLI. In order for SLI to work with how you currently have your gpus arranged you'd need a 40 lane cpu. You are out of lanes. Your only options are to stick your gpus closer or if you want them to be spaced like you have now buy a 40 lane cpu. 5930k or 5960x etc...

I'm positive this is your problem.

newtekie1 · Jan 8, 2017

Actually he has to space them out farther.

The board should have come with a longer SLI bridge to let you do this.

R00kie · Jan 8, 2017

Yes, people are right here, the second card needs to be in the third full sized PCI-e slot for the SLI to work on the 5820k. Thats how I had my 970's before.

Solaris17 · Jan 8, 2017

sounds at this point like pci-e bandwidth or slot issue like the others have said.

"Set up G-sync" is showing on my current monitor which is where I took the screen shot (Which does in fact have G-sync). I meant that I didn't have G-sync on the two extra monitors I also tried it out on AFTER my current monitor.

I used the switch in with the 2 way led's enabled for my motherboard and it's lighting up PCIe x16_1 Slot and PCIe x16_4 slot. I actually had my cards set in x16_1 Slot and x16_3 Slot.

I do have a longer SLI bridge that was included with the motherboard. I could use it test the GPU's in further lanes. Should I be testing the second card in any of the other lanes like x16_4 slot or x16_5 slot?

erocker · Jan 8, 2017

As per the manual you want to use PCIe X16 #1 and ~~PCIe X16 #3~~ PCIe x8 #4. The two slots with the white LED's above them.
Also, your CPU is limited to 28 lanes.
