Hi All, I have scoured the internet and I cannot find a solution so I am hoping the forums can help me out.
Here is my problem, I can't get my GPU to run in Gen 3 mode. PCIe 3.0 x8 or PCIe 3.0 x16. It either defaults to Gen 2 PCIe 2.0 x16 or PCIe 2.0 x8. The Asus website says that this motherboard supports PCIe 3.0, so I don't understand what's happening.
I have the follow items and here is what I am doing with them and what happens. Assume that my drivers and bios are fully up to date.
Asus z97 Pro Mobo with latest bios version
4970k CPU
1080ti GPU (this is in my primary PCIe 3.0 x16 slot on my mobo)
EVO 960 m.2 in a PCIe 3.0 x4 expansion slot. I put this in my second PCIe 3.0 x16 slot(not the primary)
I am not running the m.2 on the m.2 port because it will only run at x2 speeds and that results in a read/write of 833/805mbs.
When I put the m.2 in the PCI expansion slot, I get twice the read/write because it's running at x4 speeds.
When I put the m.2 in the PCI expansion slot, it drops my GPU from x16 to x8 mode, and it stays in Gen 2.0. Why won't my mobo run my GPU at gen 3.0 x8?
As an fyi, when all i have in my PCI slots is the GPU, it still only runs in gen 2 mode at x16. I'm just trying to figure why this mobo says it supports gen 3.0 but doesn't ever run in that mode.
Thanks for any insight or advice.
