I've, been trying everything I can to get SLI to show/work, I know the bridge is good. I guess my question at this point is do I need to use PE1 and PE4 for SLI to function, or can I used PE1 and PE2? Also, might want to add only running the 28 lane cpu. 5820k.

Have you updated the drivers to those GPUs?
Have you tried each GPU separately and in each PCI-E Lane?
Have you tried different power cables from the PSU in case one of them isn't working?

Newest drivers are installed, And I would test them in different slots, if I wasn't running a water cooling loop that is all set. Both cards are reading like they are supposed to and the bridge I am using is good. My brother in law was just running these cards in SLI on his Asus X99 WS-E board. I am thinking it might just be that becuase i am using 1 and 2 instead of 1 and 4 that might be disabling SLI.

Do the GPU's at least show up in BIOS or are you saying in general they are seen in BIOS/Windows but can't enable SLI in general? Btw, it shouldn't matter if you're using slots #1 and #2 or #1 and #4. Make sure your PCI-E dipswitches are fully enabled. Its possible it might have been disabled accidentally during installation or what not.

I am running 2 780 Ti 6gb cards, and yes both show up in bios and windows alike. And the SLI feature doesn't show up at all in the control panel, got another computer next to this one and it has 2 670 FTW 4GB cards that is running Windows 10 and it has no problem showing SLI option.

I would drain the PC and stick those 670s in the same slots with the same power connections from the PSU to see if its the PCI-E slots or PSU connectors.

I got it all figured out it was the second card not allowing SLI.

Can you be more specific as this thread can be useful to someone else that might have the same issue as yourself. Thanks

The second card wasn't syncing with the first card for SLI wasn't anything to do with slots, I think the specs might have been different just slightly as those 2 cards weren't purchased together. Not entirely sure as to why but I swapped out to the third card that was purchased with the first card that i had, and It was showing the option for SLI. Beyond that I can't really provide much more help than that.

Yup, sounds like the two GPUs are compatible from what you're saying. If you can, give us the make and model of the GPUs.

At this point, emailing us with specific information about the cards would be advised. The information we need can be found in the Nvidia Control Panel. Basically, register the cards, then email us with the device IDs of the cards. We can attempt assistance from there, if they're still under warranty.

Satiasha,
If the cards part numbers end in a -KR, they should be under warranty still, as it comes with a 3 year transferable warranty. Unless they were recertified B-stock cards, then they would only have a 1 year warranty. I'd recommend contacting us with the serial numbers so we can confirm the warranty status for you.
