Hi I picked up my first 980ti to add into the farm. It sounded like a good idea at the time but does not seem to be performing as well as expected. (Compared to my others - 950/960/970) I'm only getting around 18MH/s and it sounds like I should be getting more. It's running on Mint 17.3 with ethminer 1.1.4, does anyone have any suggestions for the optimal command line options? If I can't get better then that I might as well return and get a 970. Thanks for any help.
You should be able to get 20+ by forcing the card into P0 state:
