Anyone managed to get 4xx and 5xx running on same rig?
Man I think I tried about everything now.
I got 2x 470 (modded)
2x 480 (modded)
1 570 (modded)
With the Crimson 16.x.x drivers I can easily get my 470's and 480's but the darn 580 just shows as standard VGA.
I even tried the latest greatest 17.something driver and that was a mess lol. It showed all 5 cards but never would actually load the drivers correctly..
Grrr gotta be a way lol....
Yes. I have mixed rig with 480 and 570. Simply use latest AMD driver, patch it and start mining

Could you explain or link to the patch please? I think your talking about skipping sig check but i have never done that. Thanks for any help
Uf, I am getting sick of people who dont want to spent their time and search on google, rather spent time of others, who wants to help. Next time I will better not help.
