Most important thing is to get your memory strap correct on your GPU bios. The tighter the better. That being said, the same settings you used to mine ether with may or may not work very well with this miner. It all dependents on your GPU's. For rx470 4gb you should expect to be in the 40's sol/s. For rx480 8gb you should expect 49-50 plus sol/s. I don't have any rx 470 8gb so I cannot comment on them.
