Hey there,

I am new to coin mining, but i have a question about my rig. I have a ASrock motherbord with 6x a AMD RX570 4GB with a 1700W PSU to mine with, but i experience a strange "bug" or something.

I have Simpleminer on Ubuntu as mining software where i told the miner to mine Etherium and Siacoin simultaneously.
Per GPU i have around 15 or 16 (17 when overclockingg almost 100MHz) MH/s, while people on the internet get around 30 MH/s with this cards.

Another strange thing is if we disable Siacoin to mine, the mining speed of Etherium will drop to 14 to 15 MH/s. Strange isn't it?

Is here somebody who can help me or tell me why this happens?

Sincerely,
Justin
