So I just got my second 6950 in the mail. I plugged it in and only have 1 Crossfire bridge and put that in. When I turn on my PC, only 1 (Middle) out of 3 monitors turn on and when I check the device manager, I only see 1 'AMD Radeon 6900 series'.

Am I supposed to see 2 and is it mandatory to have 2 Crossfire bridges to get both cards working?

Thanks in advance.

EDIT:

Power Supply: 850 watts
GPU's: (Both) VisionTek 6950 (2GB)

Just did, both cards have power but still no luck. I went to CCC as well and can't find an options to enable Crossfire.

EDIT: I still see only 1 card being shown in Device Manager.

The GPU's turn on. I put one GPU in and checked if the monitors turned on, they did. I put in the second one and that monitor worked properly as well.

But to be brief, yes, the fans did spin.

Both PCIe slots and GPU's are working properly.

Do you have an extra bridge? Try swapping it if you do
Might be a defective bridge or if anything defective pins on the gfx crossfire pins?

I don't have an extra Crossfire bridge.

My PSU manufacturer is Thermaltake.



I've tried that. Nothing.

Hmmm, I had problems with a pair of 5850's, one would randomly stop being recognized, but if I removed the bridge they would always both be recognized just fine. I would contact your customer support for your motherboard at this point, kind of baffling, sorry.
