Rampage IV Extreme only running two of three 780's at PCIe 3.0

post #1 of 3
Thread Starter 
Doing some fiddling around today and noticed only two of my three 780's are in PCIe 3.0 according to GPU-Z. The two in the full 16x slots are but the middle one that only supports 8x is not. I tried to reapply the hack to force it like I did with the other two cards, but no luck. Is this slot only able to run at 2.0 or am I missing something?

BTW, using an overclocked 3820 for the CPU. That might be part of the problem too. Maybe it's time to bite the bullet and get that 4930K.

Hmmm... not sure how I fixed it, but I did. Ran the hack a few times in a row and rebooted. Now all three cards report as being PCIe 3.0.
