I've got an odd problem.
I have a board (DFI LP nF4 SLI-DR) here that will not pass POST if I have the video card inserted in PCI-E x16 slot 1 and it gives a video error POST beep, but if I use the secondary slot (Slot 3) with the same video card all is fine and the system will POST and run normally (aside from the issue of having to run the card in the secondary slot). It doesn't matter whether I have the video set up for normal mode or SLI mode, the system won't post with the video card in the primary PCI-E x16 slot either way.
Problem here is that if I run my video card in slot 3 I am limited to x2 bandwidth at normal settings, and the only way I can get anything higher than that is to enable SLI and then I can only get it up to x8 but cannot get full x16 bandwidth because only slot 1 can do that.
This is some sort of hardware fault or short as far as I can tell, as when I run the card in a different slot all is fine, and putting the video card in slot 1 gives the same result as running the system with no video card inserted at all. It's like the board doesn't even detect anything in PCI-E x16 slot 1 even when a card is inserted.
Anyone ever had similar issues and/or have any suggestions for a solution?
