hi all, i was wondering if someone could help me. I'm putting a computer together for a friend using some of my older parts. I have 2 fully working HD5970s. and trying to get them to crossfire, llike I had in my old system.
we have a gigabyte p67a-ud3-b3 board.. The graphics card slots are a pcie 16x and a pcie 4x slot.
and the problem is the card in the bottom slot only runs one GPU.
So when they are both plugged in there is only 3 gpus showing in device manager.
Is there anything I can do to get the second gpu running on the 4x slot?
I have rolled back to older drivers as people have mentioned that crossfire doesn't work with the latest. I have tried both cards in the top slot and they both work fully there.
It's just as soon as I put it in the bottom 4x slot it runs only one GPU.
Another thing I have noticed, is that the bottom card isn't recognised at all when the sound card or wifi card are installed in the pcie1x or 2 slot.
Both of these my friend needs.
So is it a no go for crossfire with this board!?
Looking forward to any replies, as this is racking my brain!
