Cleaned PCIE and bridge contacts on card with 91% Alcohol and swapped cards around numerous times. No change, other than my patience getting shorter and shorter. :shakes:Quote:

Did you try just having a wet dipped q-tip or something and just try to stick it into the pci-e connector and swipe it? I know on my board it got rid alot of junk. Also if you have one of those rocket air blowers try gently blowing into the pci-e connectors on the board. I wouldn't recommend dustoff, too powerful.
It's worth a try, but from the looks of it, it seems to be your board.
Also do a inspection of the pci-e on the cards, you never know if you might find something.
You mentioned that you did many installs. When Windows hardware found comes up, it asks three questions. One is search for drivers, another is ask me later and another is don't ask again (or something like that).
If you ever, ever, say don't ask me again..you will never, never be able to use that hardware again. It's just a thought, maybe it's your case or maybe not, but I had the same issue with a monitor, that always asked to search and when I said don't ask again, I could never do anything with it.
Sounds like a hardware issue, most likely with the PCIe slots themselves. Try cleaning the slots out like Cookiesowns recommended :shrug:
I'd think that once the 1x PCIe issue is fixed, CF should enable.
Could it be a PSU issue?
I've been running a Corsair 620w for about 6 months now running 3 HDD, 2 MSI Hawk 5770s, MB, Water Pump, and 5 fans without issues. Could the PSU be on the way out and causing my cards to default to a lower setting?
PCIE slots cleaned, problems are still there.
It's not a PSU issue.
It's a motherboard/video card issue.
I had this exact same issue - tried all the same things you did; even fresh OS installs didnt work.
Turned out to be 1 of the cards was faulty. RMA'd it and got it all working again.
I know you said you tested your cards but these symptoms are EXACTLY what I had.
Hmm.... Ok. Got another thing I can try.
I have a 4670 in the closet that I can dust off and give her a run. If I install her in the x16 lane it should run at x16. If it also defaults to x8 in the x16 then it cannot be my cards.
That's weird. I know you have tried everything, but could it be possible you messed up your bios settings by accident? Especially since you are overclocking. I have had unstable OCs that I thought were stable and I went on for days without realizing the bios settings were set back to default after it restarted while I was away and I was so confused to why everything was running so slow. I would double check every setting in the bios possible. I would even bring your OC back to stock. Even try swapping ram out, and reverting to an older bios (this could be the problem actually).
Worst thing you want to do is RMA, I know how agonizing it is waiting for broken parts to come back. Have you taken a close look at the cards and the board to see if any components such as maybe resistors that are missing or look like they are missing somewhere?
maybe the xfire bridge is damaged? you got another to try?
*Problem Solved*
RMAed the motherboard and all is good now. Glad to know my GPUs are fine.

Thanks to everyone for your help,
OCM :up:
Glad you got it fixed. I had a CF rig that 1 card stopped working randomly until I lightly lifted on the unsupported end of the card. Problem became more frequent until I pulled that card.
