I am trying to find out how to use farm mode and when. Do you need to run ethminer in farm mode if all the GPUs are connected to the motherboard or just when you are connecting multiple machines to one geth RPC server? When I do try and use -F , ethminer can never find the RPC server even though the default is set to 127.0.0.1.
Also when I try to add the --farm-recheck parameter I also get a syntax error. I am typing --farm-recheck 100.
Thank you for any help. I cant seem to find anything on it.
