So I am running a pair of GTX 670 on SLI. I have an Asrock Z77 Extreme4 with a 3770k so the pcie runs at 3.0 speeds. Here is my problem:
For easier explanation, lets call the cards gpu 1 and gpu 2 and the 2 pcie slots pcie 1 and pcie 2.
1)When I plug in gpu 1 in both pcie 1 or 2 slot. Everything runs perfectly.
2)However when I plug gpu 2 in pcie 1 slot it runs perfectly but when I put it in pcie slot 2, any games or benchmark that I run causes massive stuttering. This happen when in SLI or when the card is running alone (even with the other gpu physically removed). It only happens on pcie slot 2. But with gpu 1 it work flawlessly on both pcie slots
What could be the issue? I am completely at a loss?
