Hi guys. I'm having an issue with a GTX 280 - regardless of what machine I stick it into, it will only run at PCI-E 4x... I looked at the board (physically) and I couldn't find any signs of damage. Any ideas? Could it be a video bios issue?
How about contacts on PCI-e slot on GPU ?
In what boards have you tried GPU so far ?
Is it PCI-e 2.0 x4 or 1.x x4 ?
Tried it in a Zotac Nforce 680i and an Asus P5K64-WS (Intel P35). It runs at PCI-E 4x 1.1...
Since when ?
I read something about it. Can't remember the details.
You know, I always take annotations on hints and tricks and so I did a search with keywords "x16" x8" in my text files - No joy.
Mind draws nothing but card falling back to x8 due to missing components.
Double check with a magnifying glass, compare with photos. That's what I would do.
Nbitor and NVFLASH solving issues? Hardly, but check it out.
I guess x8 is fine, x4 hits performance, but hey, you are the one who likes engine and speed !? I've seen some guys installing a damn graphics card in the x1 slot! 😎

I'll check it out, see what comes up. I'll also test the card on a modern mainboard.
Maybe you are in these categories:
nForce 650i SLI = nForce680i = PCI 1.1
GTX 280 = PCI2.0
In this scenario the card uses the bandwidth of PCI 1.1, no problem. So the card is acting up.
nForce680i = PCI 1.1
GTX 280 = PCI2.1
A BIOS update is necessary (not feasible and chances are the card is acting up - PCI 2.0 and PCI2.1 provide same speed).
Don't even know what the heck is PCI2.1, I just read a little bit on this matter. 😈

New board = PCI 3.0
GTX 280 = PCI2.0
It will mean a lot in your investigation. Good luck.
