I was wondering if anyone knows the machine enough to tell me why is it there is such fluctuation in the hashrate (GH/s) with the Dayun Zig Z1. I sometimes see my Dayun Zig Z1 is running at 11.56 GH/s and other times it is running at 2.67GH/s.

Does anyone have a valid explanation for this particular issue?

Is it because the machine is mining with the algorithm Lyra2REv2 or does this have no importance as to why this is happening?

If you can kindly explain in detail I am kind of a noob.

Thank you,
