Re: PhoenixMiner 5.4c: fastest Ethereum/Ethash miner with lowest devfee (Win/Linux)

Mystery solved!

Thanks for posting the logs, they definitely helped to see what the issue is. It's very simple: you have -coin etc on your command-line (or bat file), which forces the miner to mine ETC, and this logically leads to 100% incorrect shares when trying to mine ETH. Just remove -coin etc from your bat files (or config.txt if you are using config.txt file) and everything will be back to normal!

For everybody else with 100% incorrect shares problem - check if the miner is reporting Mining ETC on instead of Mining ETH on. If this is the case, find and remove the -coin etc parameter from your bat file, or config.txt file.

Hi,

Thank you for your reply... yes removing that worked!

I remember a few months ago with a DAG change there was a post that said that adding that helped stability.

The PhoenixMiner readme says:

-coin <coin> Ethash coin to use for devfee to avoid switching DAGs:
auto: Try to determine from the pool address (default)
eth: Ethereum

So, it seemed Ok to use. The strange thing is, I have been happily mining with this setting for 2 months and have been receiving eth (and not etc) from ether mine.

I have now changed the setting and I'm hashing and receiving shares.

I have noticed though that my NVIDIA cards GTX1070 8GB are getting lower hash rates. They are both the same and I'm getting 19.2 MH/S and 25.8 MH/S.
I have previously used the included ZOTAC software for overclocking. (was getting stable 29 MH/S before)

Do you have any ideas why the hash rate is lower?

I would much rather set all the overclocking within the .bat file but I really struggle as my system is multi GPU.

How would you change my .bat file...I previously had '0's against GPU1 and GPU4 which are my NVIDIA cards. I tried turning off the ZOTAC software and changing cclock and mclock but it made no difference. Just looking for some best practice.

Thanks for your help. If someone has time to answer my additional questions, I would appreciate it.
