x99 PCI-E Lanes when running in SLI

post #1 of 2
Thread Starter 
I recently purchase a used 980ti on the cheap to run SLI. Current PC:

5820k
EVGA x99 FTW
2x EVGA 980ti(one is SC version, other is FTW version, dont think this matters)
16GB RAM

I know that the 5820k only supports 28 PCI-E lanes. So I cannot run x16/x16 for both cards. Right now I have one of the cards in slot 1(16x) and the other in slot 4(8x).
Manual(http://www.evga.com/support/manuals/files/150-HE-E997_Part1_v2.pdf)

GPU-Z Reports first card running at 16x link speed, and the other one at 8x. Question is, is this the correct way to have them plugged in? I've never heard of running cards in SLI at different Link speeds, and I just want to make sure its not going to break anything.

Every mobo has its own way of handling SLI. If your mobo manual says to stick your cards in the 1st and 4th slot, then yes you have it right.
