Some quick feedback for Claymore on the messaging used with regards to the DevFee. When I first read in the logs "DevFee: stop mining and disconnect" I thought it was telling me to stop mining because the Dev Fee wasn't getting "paid" properly. As in, "you aren't paying the Dev Fee, stop using this software". I see now based on your response below that this actually means that the DevFee mining has stopped and has disconnected from the pool. You may want to consider changing this to something like "DevFee: stopped mining and disconnected". Or maybe add something like "DevFee: mining complete, thanks for your support".
Maybe I'm the only one that was confused by this but if there are others like me it could help clear things up! Thanks.
Miner shows everything related to devfee. It must show "DevFee: start mining" and after 36 or 72 seconds it must write "DevFee: stop mining and disconnect". You can enable logging to file with option "-dbg 1" and then search all these strings. If you see some strange things, please PM me the log file so I can check it.
You can also decrease "-ethi" value to "8" or to "4" and check if it works more stable. This miner loads GPUs more than standard miner so if you overclocked GPUs you should check stability of this miner without overclocking, you can assign only one rig for such tests.
If you think that this miner steals your power you can download WireShark and check all packets that miner sends when you see something strange, it is not a complex task. And, of course, you can wait for more stable version if current version does not work for you, or do not use this miner at all.
