SLI on pcie#1 and #3 - Less efficient?

post #1 of 3
Thread Starter 
Hi all.

I have a z77 Fatal1ty that is capable of running tri-SLI. My question is, if I run a gpu in the first slot and one in the 3rd allowing it to breath more, would it still run at full speeds?

The first two PCIe slots are 3.0 X16 and the third is 2.0 X16. Therefore, the first two in SLI will run x8, x8. The 2.0 x16 slot runs @ x4. So the answer is - it will not run as efficient in the third PCIe slot.
