Can't Enable SLI

[Pervy GamerHax]

I can't get rid of this error that stops me from enabling SLI in the nvidia options.

to use maximum 3d performance connect the sli-ready graphics cards with an sli connector


Here's my stuff

My other graphics card is this

I tried 3 brand new SLI bridges in all orientations on both connectors.
Reseated graphics cards and all that.
With this motherboard I can't swap the card's pcie slots because the SATA ports block the evga one so didn't try that but i'm pretty sure it's not that.
Tested both cards solo and they're fine.
They're detected just fine in windows as GTX 970 (1) and (2)
I reinstalled drivers with display driver uninstaller and reinstalled.
I removed 1 card, removed drivers, installed drivers, put the other back in with no SLI bridge, let it install automatically, and set PhysX to CPU, then restarted with the SLI bridge and still didn't work.

How can I fix this?

Try a BIOS update for the motherboard. If that does not help, try Gigabyte support since they say the board supports SLI.

Only time i've seen this issue is with a unstable gpu bios, outdated motherboard drivers/bios.......you have done the gpu driver fixes so now see if there is a motherboard BIOS update.
