Hi I have a problem with my rampage IV, use the 1202 bios, I have GTX 680 GPUs with PCI-E 3.0 in GPU-Z, I have enabled in the bios PCI-GEN3 but on the first bios screen keeps telling me using PCI-E GEN 2, anyone know how to fix this? Thank you.

The nvidia drivers do not yet make use of the gen3. Limited at nvidia end, not a motherboard issue 🙂
Intel Core i7 3960X 4.4Ghz @ 1.28v

Yes, the initial 3xx.xx drivers had Gen3 working. not the later released ones, as stated on nVidia homepage.

But with the old version driver also told me PCI-E Gen 2 at the beginning that is the problem you see?

Patitoesp what you are seeing is simply the GPUz telling you what the PCIe lane is configured as. You are not getting Gen 3 from the graphic card.

By setting Gen 3 in BIOS you are enabling that capacity in the PCIe slot it will be utilised only if the hardware is able to use it. The Green team took away that capacity. They will bring it back when they fix what ever it was they needed to fix. I have no idea what or why they removed Gen3 from the drivers.

Think of it like this. You have a SATA 6G port, if you put a SATA2 Hard drive into that port it is still a 6G port and will be recorded as one. However the performance it delivers will be limited by the hardware connected to it.

That is how I see it. Hope that makes sense to you. 🙂
