-mode   Select mining mode:
   "-mode 0" (default) means dual Ethereum + Decred/Siacoin/Lbry mining mode.
   "-mode 1" means Ethereum-only mining mode. You can set this mode for every card individually, for example, "-mode 1-02" will set mode "1" for first and third GPUs (#0 and #2).

-dcoin   select second coin to mine in dual mode. Possible options are "-dcoin dcr", "-dcoin sc", "-dcoin lbc". Default value is "dcr".

-dcri   Decred/Siacoin/Lbry intensity. Default value is 30, you can adjust this value to get the best Decred/Siacoin/Lbry mining speed without reducing Ethereum mining speed.
   You can also specify values for every card, for example "-dcri 30,100,50".
   You can change the intensity in runtime with "+" and "-" keys and check current statistics with "s" key.
   For example, by default (-dcri 30) 390 card shows 29MH/s for Ethereum and 440MH/s for Decred. Setting -dcri 70 causes 24MH/s for Ethereum and 850MH/s for Decred.

-dcrt   Time period between Decred/Siacoin HTTP requests for new job, in seconds. Default value is 5 seconds.


-dpool    Decred/Siacoin/Lbry pool address. Use "http://" prefix for HTTP pools, "stratum+tcp://" for Stratum pools. If prefix is missed, Stratum is assumed.
   Decred: both Stratum and HTTP are supported. Siacoin: both Stratum and HTTP are supported, though note that not all Stratum versions are supported currently. Lbry: only Stratum is supported.

-dwal   Your Decred/Siacoin/Lbry wallet address or worker name, it depends on pool.

-dpsw    Password for Decred/Siacoin/Lbry pool.
