ATI 4670 issue.

He has 4670 in X-fire. Don't know why but lets continue.
To the OP, do you have Crossfire enabled in the CCC? What PSU do you have?

Yes I have crossfire enabled, my PSU is a 700 watt.

If you change the PCIex slots for the cards, still only the first card is visible in the CCC?

I will try doing that hallow.

Sorry about the delay. Yes they are working when I switch slots.

Both are working? Both are detected? If yes, then maybe the first time you didn't seat the card properly.

Nope, still only a single card detected. Could it be a system glitch and not the hardware?

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?

You mean this board:

PCI Express 2.0 x16:
2 x PCI Express 2.0 x16 (1x PCIe x16, 1x PCIe x4 or x1)
Do better searches next time.

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:

Hmm...probably.

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.

Will do, I see them relatively cheap on newegg. Once I receive the bridge, how do I go about installing them as this is the first I am hearing of this?

hyyyyyyyy i have same prob but you both need to know 4670 have internal crossfire bridge (sapphire 4670 1gb mine)
