After seeing your post i removed all drivers installed with guru and then did a clean install of 16.9.1. Then downloaded your latest miner and still nothing worked. Even my older cards. I also installed AMD SDK 3.0 as well. Tried all kinds of different conf settings and have given up for now. Went back to mining with my older cards. Ill just mine XMR with the RX 470/480 i have. I really dont understand this at all. 😕
