That GPU is not very powerful from a mining standpoint, it is a mobile gpu and it just does not have the power of a newer Desktop GPU I am using a Radeon RX480 8GB for instance and I get around 38Mh/s the fact it is Nvidia could also be a problem some miners work better for Nvidia some for AMD, but the research I have done shows AMD tends to mine better. This is a guide to get someone started but every person has different hardware, and there maybe better software for an nvidia /aka different miner etc. I do not use Nvidia so I am not 100% sure, maybe someone will see this that knows more about mining with Nvidia, but I would not expect ALOT from a mobile GPU thanks.
