Figured I'd post here asking for help, I have a P8P67 Pro that obviously has 3 PCI-Express slots. Two run at x8 when both are populated then the 3rd is x4 or x1 depending on the USB Controller.

Whenever I run SLi, my second card runs at PCI-E 2.0 x1 for some odd reason lol Even if I take out the 1st card and run the 2nd card solely by itself, it runs at 1x...



There's a screenshot lol Notice the bus says PCI-E 2.0 x16 @ x1 2.0...

Any suggestions or possible fixes I could do or anything? If I run a single card in the 1st PCI-Express slot, I get full x16 bandwidth.

There are no other cards occupying any of the slots other than the Navy Blue (x16) and Grey (x8) slot. I'm on 1053 Bios and I've tried 1003 along with optimized defaults.
