@Claymore, another question, using tuning usually gets my ip banned, first of all, gpu is not overclocked, however, hashrates shown differs on multiples same gpu model, for example, rx 480 8gb, card 1, shows 690 h/s, rx 480 8gb, card 2, shows 660 h/s, the only way for card 2 to reach card speeds is to tune -h values, up and down -h 1024 to -h 992 and back to -h 1024, is there a way you can make highest values stable, i mean, all gpus reach highest possible hashrate?
