Yesterday, I went out and bought two MSI Twin Frozr R9 280x cards and installed them last night. One card worked, and one didn't. So today, i exchanged the DOA card for a new one, and after a few reboots and such, got everything installed.
When I run Unigine Heaven with Afterburner open, it shows GPU1 usage at 98% but GPU2 usage stays at 0%. According to GPU-Z and CCC, Crossfire is enabled. Both programs list both of the 280s, and they both appear in Device Manager... but for some reason the 2nd card isn't doing anything? It doesn't even warm up during benching like the first card. Also, the Crossfire bridge is installed
Last thing - both cards are at stock speeds, I haven't tried overclocking anything on them. I tried to download the 13.11 Beta driver, but whenever I go to install it, it gives an error message saying
"AMD Catalyst Mobility cannot be downloaded due to incompatible hardware/software on your computer. Your computer does not contain a proper graphics adapter"
My specs:
2 MSI Twin Frozr R9 280x (Crossfire)
Board - Asus P6X58-E WS
CPU - Intel I7 970 hex core (overclocked to 4.2ghz)
PSU - Rosewill 1000 watt
Ram - 24gb DDR3
Does anybody have any ideas?

Best solution
Both are definitely enabled. Do you also have Unigine Valley? If not, get it. Use the Extreme HD Preset and run it.

There is a difference between bus interface? I don't know if that means anything or notThat is common. In multi-GPU systems, on some motherboards, the second GPU slot runs at x8 speeds, while the primary runs at x16. This is the case with your motherboard chipset.
Some run at x8/x8 and some newer mobos run at full x16/x16.
Really not a concern for you.

Ok that seemed like it worked! On extremeHD, the score was just over 3000. I wasn't able to grab a screen of that, but heres a screen of the Afterburner info while the bench ran

Language please! We ban people for such things, BTW....No "f bombs".
Run the full benchmark in Valley and then post your scores here:
http://www.tomshardware.com/forum/393368-33-unigine-val...
You can also get an idea of how your rig compares to others.
Not all benchmarks/games/applications can take full advantage of multi-GPU configs.
