I connected two following ethOS miners to Ethermine mining pool (https://ethermine.org).

You can see dashboard of my address here: https://ethermine.org/miners/0x5Bf39b56e6e1698A01A5116e308e9CDf38787C7d/dashboard

While both miners have similar GPUs as follows:

Miner 1: Worker name: 3b8f42


Miner 2: Worker name: 3b903c

enter image description here

However, as you can see in my address dashboard ( Link to dashboard ) in Worker table at the bottom of the page, Miner_2 (with Worker name of 3b903c) is always significantly faster than Miner_1 (with Worker name of 3b8f42). While Hash-rate of 3b903c is around 36.7 MH/s, Hash-rate of 3b8f42 is around 18.1 MH/s .

Another strange thing is that when Hash-rate of a miner is increased, Hash-rate of another miner is decreased ! such that always the average Hash-rate of both miners remains around 50 MH/s !

What is the reason?

It looks like you just started using miner 2; if your local miner gives you a hash rate, you should believe that value over the dashboard for at least a few hours. There aren't enough data points for the dashboard to accurately compute approximate hash rate. I see each one has an average hash rate of around 35 MH/s right now. The increase/decrease thing just sounds like regression towards the mean. Eventually, I think the sum will settle to hover around 70 MH/s.

  • Thank you, Yes, now it has been changed. Would you please say how to calculate the average hash-rate (Mh/s) using GPU specifications mentioned in the question? And why the specifications of the GPU seems to be a CPU than GPU e.g. Inter Core i3-4160 CPU @ 3.60 GHz ? Thanks

    You can’t really calculate the average hash rate of a GPU a priori (see ethereum.stackexchange.com/questions/26049/…). I don’t know why there’s no GPU stuff appearing; I suspect the 4x CPU lines are due to the four logical cores presented to your software.
