I'd be grateful for help I bought a 2 gigabyte card 5870, but I can only use one. Two cards are shown device 0. They are on different tires. I tried to connect the card from another manufacturer (asus + gigabyte) but the same result. Help please.

Do you have a monitor connected to the 2nd card? If not, can you connect a monitor to it and see if it appears? If that is the case, you will either need to have a monitor connected to it, or craft yourself a DVI Dummy plug as outlined on http://www.overclock.net/folding-home-guides-tutorials/384733-30-second-dummy-plug.htmlIf attaching a monitor did not help, could you provide some greater detail about the specs of the setup you are working with?

785G? 785G supports Hybrid Crossfire, that means it supports Crossfire mode too. You are sure that your cards arent working on CF mode? check CCC. Or just use GPU-z to find out.

Crossfire mode off. Catalyst Version 11.3 Cards do not attach the cable and in CCC Crossfire disabled too.

Can you enable crossfire in CCC? I've never seen two GPUs able to mine without crossfire being turned on.

mmm do you placed a dummy dvi-vga adapter with the resistors and extended the displays? as far i known, adapters shows up as disabled only when there is no monitor attached to them.
