GPU-Z is saying my GTX 1080 FTWs Bus Interface is "PCIe x16 3.0 @ x8 3.0" and I've tried to run the "render test" and/or games but GPU-Z will never show anything different. I have my graphics card installed in the very most top PCI-E x16 slot of my motherboard, which should be running @ x16 configuration (I've triple checked my mobos manual). I have no other devices plugged into any of my expansion slots. I have a 2.5" SSD in port 1 on Sata 3.0, 2 HDDs plugged into port 2-3, and 1 Blu-ray Drive plugged into port 4. I have the most current up date bios on my mobo as of today's date, which is version 0906. My graphics card should have the latest bios revision as well, I'm running on Slave bios revision 86.04.3B.01.82
I know x8 and x16 isn't that much of a difference if any, however, just to keep my sanity, I want to be able to hit that x16. Thanks in advanced!
PS- I've also checked around my UEFI settings and wasn't able to find much. Things related to PEG/IGPU are on auto, so I don't think I messed around with any settings to affect the card running @ x8.
