SLI not showing up in Nvidia control panel

[ejg1994]

Hello, I'm completely stumped on this. I cannot get SLI to show up under Nvidia control panel under the "surround, physX" settings. Here are my specs:

Windows 10 Pro
Gigabyte Z77X-UP4 TH
Intel 3570k
12 GB DDR3 2133 Mhz
2x GTX 680 2 GB
Coolermaster 1000W SilentPro

I've tried everything I've read so far. I've uninstalled and reinstalled drivers using DDU in safemode, reseated the cards, swapped the positions, tried 3 different SLI bridges, updated my motherboard's BIOs, disabled all integrated gpu options in the BIOS, I even tried the old coolbits registry hack. As far as I can tell, the motherboard supports SLI.

I have card 1 in the PCI-E 3.0 X16 slot and card 2 in the X8 slot. Nvidia control panel, windows, and GPU-Z all recognize that both cards are there and are running in X8. Both cards work find on their own and in each of the slots I've installed them in.

I've hit a brick wall. Any help would be greatly appreciated. I'm sure it's something obvious I'm missing.

Thanks in advance!

SLI is under its own section in the control panel. https://www.computerhope.com/issues/pictures/nvidia.jpg

Also check under windows device manager to see if it recognises both gpu's at the same time.

That's an old version of the control panel. Here's what the current one looks like:

Also they are both shown in the device manager:

It sounds like one or both of the cards have a faulty sli connector. Any chance the cards are with EVGA and have a lifetime warranty?

 

[ejg1994]

Do all EVGA cards have lifetime warranty? One of them is, yes.

 

[apower101]

No, only if you bought it new and registered it within 30 days.

What are the models of both cards specifically? brand and model.

EVGA GTX 680 Superclocked 2gb
ZOTAC GTX 680 2gb

Are they both reference models? Could be worth getting them on the same bios

 

[ejg1994]

They are both reference, and I actually already have moved them to the same bios: 80.04.09.00.80

Just checking, you only have monitor(s) plugged into the primary card right?

If you have anything plugged into the secondary card it wont allow SLI to be enabled.
