why on this coin I get problems, I have 6 1080 ti video cards, the total has 400 Mh / s, but on any pool I get a maximum of 150 Mh / s
sometimes even 59.2 Mh / s
what is the problem. other coins do not have problems, even on this algorithm I do not have problems with another coin, but this coin is of low speed but it should not be so.
