ZCash is in constant development from a miner point of view. Always check for new versions as hashrates are always improving. Recommended is Claymore or Optiminer.
- Genoil ZEC miner. Again please donate bitcoin or hashrate to Genoil. If someone deserves it, it is him. Free. See here. May not be the most stable miner.
- SILENTARMY stand alone miner. Free. For linux and windows users. See here. Discontinued, but user Zawawa is still working on his fork of the project, Gateless Gate.
- Claymore’s ZEC miner. 2% fee with SSL. See here.
- For Nvidia, there is Nicehash Miner (0% fee), with the EQM update. See Nicehash download page and the bitcointalk thread for the update ! (can only mine at nicehash with EQM miner).
- There is also EWBF’s CUDA Zcash miner for Nvidia cards (Very fast). You can mine anywhere, 2% fee. Get it here !
- And finally we have Optiminer. Fee is included, so the speed you see is what you get.
