-It's definitely worth it until you've some cheap (or free in your case) electricity.
-Each of your Sapphire RX 570 should be generating at least 27 Mh/s. Have you tried using some of the integrated overclocking options of Claymore miner? Which miner are you using right now?
-Monero is right now like 20% more profitable to mine than Ethereum, you should move to it.
-If you want to keep Ethereum, you may first mine Monero and then trade it for Ethereum. That way you'll get like 20% more Ethereum than directly mining it.
First I'll address your question...
No it is not worth it because you are giving up extra ETH you should be getting.
Each of those cards should be getting 28.5 to 32 MH/s.
My slowest 6 card RX 570 / 580 rig gets 178 MH/s, most get over 180 MH/s. I have a few getting 190+ MH/s.
Have you bios modded the cards? It is not hard.
https://github.com/jaschaknack/PolarisBiosEditorHave you overclocked them? It is not hard.
https://forums.guru3d.com/threads/overdriventool-tool-for-amd-gpus.416116/Have you switched the AMD drivers to compute mode?
Now, that said if you are just getting into mining you might not want to be changing things up often. That said there are some cryptonight coins that pay better then ETH at the moment and have high enough volumes on exchanges if you try to sell. For example... XMR, SUMO, IPBC
To mine those you will need a cryptonight miner like xmr-stak or xmrig.
https://github.com/fireice-uk/xmr-stakhttps://github.com/xmrig/xmrigYou are asking the wrong question. The real question is: Why are you still mining eth with those cards? You can make nearl
y %25 more with monero.Soon you won't even able to mine 1/10 of what you are mining now. Just move to a GPU friendly coin.
Okay guys that gives me more clarification now.
So first thing is I am currently getting wrong hashrate and I assure that is because I have not overclocked it. I just bought it and installed on my own. I am running that one with the ethOS operating system and ASUS motherboard.
I will checkout the links provided for the overlocking and will do that immediately. However I will need to study that first as im no expert in that one to be honest.
And another tip for me is switch to monero! Okay what is the requirement for this one? can it be still ran on the ethOS or I have change the whole OS as well. Just new and learning in the mining field, hope you will guys explain this one too.
Thanks for the guidance. Appreciate it!
