Good morning.. I have asus maximus IV extreme, i7 3770k and 1080gtx but this video card run at 8x pcie.. Why don't run 16x??Bios updated to the latest version.Sorry for my bad english..
I tried with another video card but it gives the same problem.My motherboard don't have m.2 slot.. If i use second slot the videocard run on 16x with nf200..it could be a bios problem?
