I have never used an ATi card nor Crossfire or SLI. I have I have a couple ideas though. Try switching PCI-E slots. If that doesn't work, try trying 1 card at a time. If they are running at stock speeds, I have no idea what's wrong. If the one card is running at low speeds, then RMA it. I would also recommend updating BIOS drivers, that might fix your problem.

BTW, Welcome to Tech-Foruns

I thought the second slot ran at a lower speed. I'm not sure, as I never used Crossfire.
