Are there any settings in your BIOS that needs to be turned on or activated? I did some checking and read that this particular board does not support SLI but Crossfire is supported... and you have two AMD cards..

I did find a footnote regarding your board:

"The PCIe x16_2 slot shares bandwidth with PCIe x1_2 slot. The default setting is x2 mode. Go to the BIOS setup to change the settings."

So I'm thinking it was changed to X1 mode or something...
