You can use this command to mine with
Claymore's dual miner (simultaneous Shift + Decred)
EthDcrMiner64.exe -mode 0 -esm 0 -allcoins 1 -epool pool.shiftnrg.org:8008/0x8b628904b31cac58ecacdcfdd2f95c864eb93a51/r9 -ewal 0x8b628904b31cac58ecacdcfdd2f95c864eb93a51 -eworker r9 -epsw x -dcri 30 -dpool stratum+tcp://dcr.suprnova.cc:2252 -dwal ralfs.r9 -dpsw x
At this moment the official pool seems down, but you can also use the new Geilidao pool, as it has stratum support too.
EthDcrMiner64.exe -mode 0 -esm 0 -allcoins 1 -epool shiftst.geilidao.com:6001/0x8b628904b31cac58ecacdcfdd2f95c864eb93a51/r9 -ewal 0x8b628904b31cac58ecacdcfdd2f95c864eb93a51 -eworker r9 -epsw x -dcri 30 -dpool stratum+tcp://dcr.suprnova.cc:2252 -dwal ralfs.r9 -dpsw x
ESM is for stratum mode, combine it with the correct pool port, and your ready to go.
Set mode to 1 for mining SHF only. Or decrease the dcri DCR hashrate parameter to increase your SHF hash.
