Mining drivers for AMD with 13 gpu

[zenderady]

I have a Asrock H110 BTC+. All cards (rx 470 mining edition) are visible with the latest AMD drivers. If I install the mining drivers with all gpu I get blue screen with atikmdag error. If I install the cards one by one all works great up to 8 cards. If I install the ninth I get the blue screen error again. No matter which card is the 9th, no matter the riser. Any ideas how to solve this?

latest drivers support up to 12, you should read release notes for details

Post your configuration particularly on your Hardware/Software setups,

PSU ratings
Risers
Memory
CPU
OS
Drivers

also there are threads worth reading for users who are able to Run more than 10GPU's
