I recently got my computer with 4670 HD x2, but it only recognizes 1 of the cards when I go to catalyst. I can see the fan running on both cards when the computer is on though. Any thoughts / advice on this problem? I have windows 7 and my mobo is an ASUS M4A78 PLUS AM3/AM2+ AMD 770.

Much thanks in advance!

So...let me get this straight. You had:

First:
Card1 -----PCIex slot 1
Card2------PCIex slot 2
--------------------------------
Only Card1 detected.

Second:
Card2-----PCIex slot 1
Card1-----PCIex slot 2
--------------------------------
Only Card2 detected?

The linked mobo you showed me (Pyshco) only has 1 PCIe slot it seems. Mine has 2 for sure. And to hallowed, yes, only the first slotted card is recognized. Not the 2nd

I am fairly new at PC building, so I do not remember which brand of 4670 I got. And can you elaborate a bit on the Crossfire bridge and what it is so I can investigate a bit more?

A Crossfire bridge is a connection between the cards so that Crossfire can work. You can see more about it here:

Hm, I see. So if I actually buy a higher end card (I was thinking of a 5xxx to upgrade for dx11), would they come built in with a crossfire bridge? Or would I have to buy them separately? And that could be the issue.. I don't see what else it could be.

If you already have the 4670s just go and buy a Crossfire bridge.
