so gigabyte couldn't help you? figures.
so in NVidia control panel the list on theft does not say configure sli, surround, PhysX, correct?

should look like mine.
if you click on the pic it will open larger so you can see it better.

Gigabyte says its MSI's fault and MSI says its Gigabytes fault.

This is what mine looks like.





EDIT: Gigabyte suggested I update the GPU's bios so they match. I did that still nothing. They also had me place my mobo in Legacy mode. Still nothing. I have another PC I could try it in but the PSU isn't strong enough and I don't want to pull mine out haha. Just might have too.

What happens when you have one monitor only plugged in? Friend had a similar issue once. Instead of having both monitors on one card he had to plug a monitor into each, if that makes sense.

Do you have the 8-pin ATX +12 EPS supplemental power cable plugged in to your motherboard? You might not have enough PCIe bus power available. If you run one PCie card, you can sometimes get by without the extra 8-pin motherboard +12V cable, but with two cards you definitely need it.

UNPLUG your second monitor and attach it to the second card. I'm pretty sure with SLI you can only run one monitor PER card.


If the NVidia 314.xx drivers see both cards installed, and they're both the same model, AND you have a PCIe bridge installed, it should work. What PCIe bus mode does it show for the cards? Should be PCIe x8 on that motherboard and with those cards in the right slots. If one of them says x4 or x1 you might not be able to get SLI working (e.g. use the colored slots for the two boards, don't use the white/black slots if you have them).

yeah the bios for the cards won't do it, NVidia say's cards can have mixed bios and my 2 cards have different bios also.
I am just out of options. there is one driver from NVidia that was the best of all, maybe install it and if sli shows up then update too a newer driver. the driver is 295.73

I had him try the sata power cable to the mobo last night and it didn't work either

I'll give it a shot.

EDIT: Did not work also.

1 says PCI-E 16x @ 8x 3.0
2 says PCI-E 16x @ 4x 1.1

I only have 3 slots the cards are in the top 2. PCI-E slots. PCIEX16 and PCIEX8 according to the manual which are the proper slots.

per gigabyte your first 2 pci-e slots are 16x, if you put a graphics card in slot 1 it will run 16x, then they say if you have a card in slot 1 and slot 2 they will both run at 8x.
so if yours are running at a 8x and 4x then something is wrong there. they also say that the only 4x slot is the 3rd. I found all this info on gigabytes web-site so maybe call them again too verify this.
I know talking too them is like talking too a wall but maybe you can get somewhere with them.

I'm thinking board issue. My friend has the same card and I swapped his for my first one and new one etc and still didn't work. Gigabyte suggested that I still try it on the other friends mother. Looks like I'll have a tear down tomorrow.
