Try this miner - you don't need -SP 2 with the nicehash version
not working on rx 480
what error do you get and/or which miner is actually working on rx 480 ?
My 480X works with ethminer-0.9.41-genoil-1.1.6-pre
I get a "no GPU device with sufficient memory was found." error, but i have rx 470 4gb
Any ideas guys?
