I just noticed that my cards don't run at the same clock speeds. GPU1 runs at 850 stock but GPU2 is always a steady 400. How do I get my card to do it's job? It shouldn't be underclocked when I'm playing games so what's the deal here? I have two ASUS EAH5870's and they are at stock speeds at the moment.

Do you have the latest VGA driver installed? (with the latest Catalyst profile apps)
Also post your system specs.

Crossfire engages only in full screen mode also, have you been playing in full screen ?
Does gpu-z and CCC show that crossfire is enabled ?

Yeah I even have the logo in the corner to show when crossfire is being used. I run all games in full screen at 2048 x 1152.
