Glad to see you have fixed it, Himera! Somebody in amd driver team should be fired for such things.
renz496, my bios for mobo was the latest available.

well multi gpu is very complicated thing. it doesn't help it when you think AMD already have to struggle with their financial burden. hence AMD pushing hard for DX12. because with DX12 they can lessen their driver team burden and multi gpu implementation is done entirely by game developer. ex nvidia engineer once mentioned that almost half of the driver team effort from both vendor is to make multi gpu to work on existing title. that shows how hard it is just to make multi gpu to work as intended even by the one that making the gpu itself.

Well renz496, i can agree with you on "multi gpu is very complicated thing". But for me it was a shocking thing to have such issue with driver installation, because all my previous crossfire setups didn`t have any problems (except well known microstuttering here and there) and lack of good crossfire optimization for some game titles. I was also very annoyed by this bug with drivers, because i use my pc not only for games, but for work too (i do 3d stuff in 3ds max and blender).
So, i`m very glad that issue was finally solved.

Hello, Himera!
I`ve just registered to say, that i have exactly the same issue. I have two Sapphire RX470 Nitro 4GB videocards and my mobo is Asus Sabertooth Z77. I can`t crossfire them too. Tried different drivers, checked both adapters individually (they`re working good). No result, No matter what i`ve tried, i can`t install driver for second adapter.
My previous setup working well (two Asus HD7950Top V2 cards).

Yep same here my previous setup works good.
