PCI 3.0 x16 Question(Z77A-GD65) Tags: Motherboards GPUs PCI Last response: December 17, 2012 10:57 AM in Motherboards Share Firedrops December 17, 2012 10:16:33 AM About the PCI 3.0 x16 slots, will putting my single video card in the top-most(closest to cpu) have any benefits? It is said to be Quote:PCI Express 3.0 x16: 3 (16/8/4) So does this mean the the top one is running at true x16 speeds, 2nd one at x8, and bottom-most one at x4? Or does this only apply when doing multiple GPUs? I am using only a single GPU, NOT SLI. I wish to position the GPU a bit lower so that both it and the top of my mobo can receive better airflow from my side fan. Thanks in advance for your comments!

But you can install CPU-Z and test with the card in the second slot. See if it runs at X16 or X8. m 0 l Can't find your answer ? Ask !
