I just tried the V9 my speeds have improved but for some reason 1 of my cards is hashing @ 416.995 H/s now that may sound great but all the shares are being rejected by that card?
I have all RX480 all with the same bios? Rest of the cards are all hashing around the 200+ mark .

Any Ideas anyone? I have restarted my rig to see if that would do anything
