I recently got this card and it is installed on a Gigabyte GA-P67A-UD4-B3 motherboard on latest bios. It is reporting that it is running at x8 on a x16 bus. Shouldn't it be running at x16 then? I've scoured the mobo manual and searched online but can't seem to find a fix to the problem.

Anyone know what to do?
 
I'm assuming you've got it in the first slot, but is there another card (even a PCI-E x1 card) in the other full-length slot? If so, this will reduce the bandwidth to x8 whether you like it or not.
 
Have you searched through your BIOS and looked for some settings to change the PCI-E slot bus speed? It will be in there somewhere.
It's probably set to AGP 8X or something.

Alternatively if you have another device in the second PCI-E slot which automatically runs at 8X it will sadly reduce your first PCI-E to 8X speed as well.
 
Nothing running in the other pci-e slot. Closest thing I have running is a normal PCI soundcard right at the bottom slot.
 
In which case:

a) do you have another card to try
b) look for a BIOS option to do with setting the lane bandwidth
 
Hmmm, I'm off next week so I might take a road trip to OCUK and get them to look at it, and if it is the board then I should be able to swap it out there and then.

Is it worth coming all the way from Lincolnshire?

In my experience OcUK never test anything while you wait they just take it off you and get in touch after a few days.

Quoted for truth, they never test stuff there and then. Will be a wasted trip.

Yes could not be making good contact with the x16 pins electrical pins in the connector.

Yup, that's what happened to my graphics card a few months ago, after I gave it a good clean up and installed an aftermarket cooler on it. Turned out that it didn't fully fit in the slot for some reason.
 
I tried the new graphics card in my old machine and it is working fine, it was on the latest WHQL drivers so I'm getting those for my new rig as well to see if it reports properly. Will update later once I've done it.
 
My 460gtx did this on my old board. It was fine but one day decided it wanted to be at 8x. I tried all sorts but cured it by loading an older bios for the board and then re-flashing the latest bios again...
 
you probably wont notice any difference in the performance if it was on x16 mode, as when you go sli both cards run at 8x and the difference is probably 1fps so i wouldnt be too woried if you cant sort it
 
Not that it helps but i had to RMA a Zotac GTX 285 as it was displaying 8x and not 16x.

The RMA was accepted and i had the card replaced,it could be a faulty card.

I think his point was that it makes very little difference on an SLI system when both cards are run at x8, so I'd doubt it'll have a massive impact on one card at x8. It is annoying though, so I'd be tempted to try MOOGLEYS' suggestion.
