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
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.
Google for atikmdag-patcher...
So now I got all 5 cards but one is non-working. So if a 470 is failed and I change the riser to another port and reboot then a 480 will be failed for example. The other 4 will mine. Anyone else have any suggestions (and yes I am researching for an answer elsewhere) lol
Well I finally gave up. Skipping sig check allowed new AMD drivers to fully load on 4 of the 5 cards. After numerous tries I could never get the 5th card past error 43 or whatever it was. I pulled the 570 out. Am now building yet another rig and will try again. This time all 570's and again with 5 cards. Fingers crossed...
Well I decided to keep pushing lol.
Here ya go...
In the end I upgraded to Windows 10 latest version, installed 17.4.4 AMD and most importantly patched it with pixel patcher https://www.monitortests.com/forum/Thread-AMD-ATI-Pixel-Clock-Patcherbefore rebooting. All 5 cards are bios modded.
