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?
Post your configuration particularly on your Hardware/Software setups,

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