[SOLVED] Very strange GPU issue!

[MasterCodem]

I've got two GPUs running in SLI for almost a year without problems(almost).
Today i installed a m.2 ssd,
now my GPUs only runs in the first PCI-e lane (in other words, no sli!)
The second PCI-e lane does not seem to function.



I've tried taking it out, and clearing CMOS.
My bios is the newest.



EDIT:







Processor: i7 4790k
Graphics Cards: GTX 1070 x2
Motherboard:Asus z97-a

Is the SSD detected and working?

maybe if an ssd is installed on your motherboard it disable the another pcie x16 that you are using sli with im not sure but im guessing btw try to remove the m.2 and see if both cards are working together

I think thekillerx10 has sussed it out. Have a look in your motherboard manual. It's likely that the use of the M.2 is affecting the PCIe configuration.

The M.2 is working yes! But, i tried it with and without. Sli will not run.

I also noticed that when i have one gpu installed, it only runs at 8x...

My pc used to work just fine

When you run with one GPU, is it installed in the slot closest to the CPU?

 

[MasterCodem]

Yes, it is. If i run it in the other slot, it wont post, just the red CPU led is turning on.

Maybe there is some insight in your motherboard manual?
