This coin can not be mined with NVidia cards.
I tried all CryptoNight miners ( ccminer, various forks) and all of them give JSON RPC error.
This coin obviously is created to be mined with AMD.
Overal expression this coin give is that he is extremely not user-friendly. There no simply gui wallet and you can not simply start mining as of the rest of the coins.
you can use xmr-stack-nvidia .. youtube video if you don't know how to use it
