Can someone tells me why is my log shows 15-20% stales? It's only showing on Phoenixminer, but other miners doesn't says that? Am I really losing that much shares?
On ethermine pool dashboard, it only shows 1-2% hourly. >15% reported locally is very weird? This is a bug? FYI, Ping test shows 7ms and no packet lost, connected to closest server, and tried no overclock, still the same.
People been telling me to switch to other miner, but other miners just simply not reporting stale shares at all. Please advice. Or maybe developer can explain what happened.
Thank you!!!
