My rig has 6 pcs of 1080 , hash rate about 221 MH/s.
It alway connect to port 6000, that is for hi-diff.
Do I need to change to port 2000 , lo-diff? and How?
if you are using the current CWIgm-0.9.7 - this is not possible ...
the current miner is locked to lodiff port 2000 ...
this will change as we will add a port parameter for you to choose in the next small update ...
the diff was a little too high a target for the lodiff stratum port - thats changed now - and will not hit higher than 2.5diff ...
port 6000 however - starts at that diff ... and can handle all the hash you can throw at it ...
