I have 2 cards, ASUS RX470 4G mining edition and Sapphire Rx580 8G..They both do great by themselves but I cant get them both to run at the same time on different drivers. No matter which drivers I install in which order, one of them tries to run both cards. Even the Crimson blockchain drivers, which dont even the support the 470, automatically label it a 570 and installs 570 drivers, which dont work very well on the 470. When I uninstall 1 card during installation, as soon as I restart with the other card in, the drivers take over both cards. So I am stuck either running ASUS drivers on my 580 or The Crimson drivers on my 470, robbing one or the the other of hash rate. EVen the recommended Adrenaline drivers also label it a 570. If it was just the label, I would say fuck it but thats not the case, the 570 drivers on the 470 dont work right.  I just want both cards to run at their max potential, there has got to be a way to lock in the drivers for one card before installing the next .  ANy help or advice would be much appreciated.
