PCI-E locked at x1 - GA P35 DS3L rev 2.0

post #1 of 42
Thread Starter 
My PCI-E x16 slot is running at x1 (according to both Nvidia Control Panel and CPU-Z) and I can't figure out how to get it to x16.
All new chipset drivers installed and there is no option to change it in my bios.

Help would be greatly appreciated since this is being the bane of my existence right now.
Thanks

Did you recently flash the bios? I had a similar problem on an ASUS 650i board and was able to fix it by increasing my PCI-E frequency to 105. But it might be a faulty board. Posts like this pop up every few months. I think the last one I saw was with the same board.

Thank you for the link, but it has over 100 pages.

Bumped PCI-E frequency to 105, no effect.

Just noticed that my board's BIOS are the F5 versions and there is F8a out.. could this quite possibly be the problem?

Try increasing the SBv, if that doesnt do it, then raising the frequency should. I have had this problem with my 965 boards and a P5K-vanilla.

Certain FSB's and raising the pci-e freq, require's more SB voltage to be stable. Little is known about the affects of FSB strap/latency for SB's...if they were, there would be a much better explanation and solution, I'm sure.

If you do flash the bios, please set bios defaults prior to doing so. If you dont, expect unexpected results!

I would not exceed 117mhz even for benching purposes. I ran ~110mhz on my previous GPU's..using 107mhz currently.

Use a quick benchy like AM3 to test your gains/losses from adjusting the pci-e freq.
