Hello guys,

I am new to mining, and i now just exchanged old gpus for new RX580 8Gb and i just installed Nicehash miner i overclocked gpu but i get only about 0,00002 worth of btc which is equivalent of about 8MH/s and this gpu supposed to do about 30...
So Can someone tell me what should i do to have this full potencial? should i set it up somehow?

Please be kind i am newbie have a nice day!
