Asus P67 Revolution PCI-E Issue

[jesyjames]

I hope someone can help me out with this.

Basically, I got this motherboard so that I could run my two 6970 gpus in the PCI Express slots using 16x interface. It uses the NF200 chipset to do this.

For the last few months, everything has been fine. The other day I checked the interface(using the latest version of GPU-Z) and it shows that the first slot is running at x4 and the other card is running at x16.

I have tried everything I can think of to get it back to x16 on both. It used to show x16 on both when I first got everything up and running.

I have nothing else installed on the computer right now in the PCI slots except the two cards. They are installed in the proper "blue" pci slots(slots 1 and 5 I believe). I have them bridged with a crossfire cable.

As a last resort, I backed up everything and did a fresh install of Windows 7 64 bit.

The interface still shows the exact same thing. I used cpuz as well and it showed the same thing.

Any ideas? I payed "extra" for the dual x16 and I find it very frustrating I am not getting it.

Or maybe I am and it's being reported wrong. Catalyst Control Center shows the same thing.


I have no idea.

are you talking about the P8P67 WS Revolution, it specifically states in the manual that if using dual cards it will operate at x8, and will only be x16 if it is a single card.

it is odd that its saying x4, what i would do is try each card byitself in the top slot to be sure its reading x16, and if to then put the 2 back in to be sure that it reads x8.

if they don't read x16 in the top slot with either card, it could indicate a bad board.

I have tried just a single card in the top slot(either one of them) and it still shows 4x with no other cards installed.

It did work at one time when I first got the board :/

I guess I will have to RMA it and then sell it. Can't really be without a computer waiting for it to get fixed.
