I had to reinstall all drivers, and it seems only 2 of the 5 cards are showing up.
Mixture of 480s and 580s, 2 of 3 580s show up, 0 of 2 480s show up.
Tried so many driver installs.
I also have mixed amd card models, what i do to reinstall drivers is:
1 - amdcleanuputility to remove the old driver
2- install the new driver i want
3- use the atikmdag-patcher right after drive instalation before restarting
hope it helps
