I have an older Gigabyte HD6850 (I know it only 220 mhs but hey) and I cannot get it to mine no matter what I try. It will mine fine on my I7, Asus z77 deluxe board but the amd Asus 990fx board with a sempron process I get this message. I cannot just keep it on my I7, I don't want any extra noise and heat in the office. I keep getting this message and if anyone has any ideas please post. I've loaded the AMD recommended drivers, tried using the disk that came with the card but catalyst would not even load. It anyone is using this particular card to mine, I'd love to hear the set up, thank you very, very much. Here's a pic of the console.
