perfect, thanks.  Switching between equihash will do for now (since these always seem to be at the top of the profitability list for my rig anyway).

Regarding which job to pick in the worker config page on MPH, there is no option for just Equihash in the "Multi Algo Auto Switch", only in the "Algo Auto Switch" section.  Am I ok to use this (just as the FAQ suggests this is more for ASIC miners etc). 

If yes, would I need to change the port to 17203, from 12023?

Thanks again
