This is a recommended update for all users Depending on several factors some shares were lost, this update fixes the issue. On machines affected by this issue it will reflect a slight increment of shares on the pool side.

Also some optimizations added to X22i algorithm.


  • Faster X22i
  • Stratum connection stability improved
  • Bugfix: edge cases with lost shares
  • Algorithm name command argument now non-case sensitivity

Some users with Vega got issues with this release, slower hashrate. So Vega users for now use this build if you have issues: https://github.com/zjazz/zjazz_cuda_miner_experimental/releases/tag/x22i_0994_amd

SUQA (X22i) is now officially supported and LUX (phi2) support has been removed.


  • New coin supported: SUQA (X22i algorithm)
    • Compared with SUQA experimental version v0.994 this one up to 30% faster
  • phi2 algorithm removed
  • Baffin and Fiji AMD families support added
  • Print hashrate per GPU enabled by default. Added new --hide-hashrate-per-gpu to disable it
  • Total amount of shares sent to stratum added to the debug-info message
  • Bugfix: Selecting a subset of gpus with -d and setting --device-gpu-threads per gpu didn't work as expected
  • Improved GPU errors checking
  • Miner restarts automatically if GPUs are not working properly (0 cycles/s issue). This behavior can be disabled with --disable-restart-on-gpu-error If disabled, instead of auto-restarting itself it will quit.
  • Improved stratum management
  • New dump output to file feature. Use -L or --log-file followed by the name of the file
  • EthMonitoring compatible: --no-color treated as a valid parameter (ignored by the miner). It makes zjazz compatible with EthMonitoring when using the miner as ccminer API
  • API summary/gpus incorrect hashrate bugfix
  • API added threads function, better ccminer compatibilily (gpus and threads API functions do the same)
  • API: Connected message only printed if --debug-info is enabled
  • First API version: ccminer-like. summary, pool, gpus and quit functions available. -b/--api-bind
  • List of failover pools added. Use multiple times -o (--url)
  • GPU timeout feature added: Application quits if new blocks from stratum are received and GPUs are not mining. Timeout value can be set with --gpu-timeout
  • Improved stats, show hashrate detailed per GPU with --hashrate-per-gpu
  • Added some debug info messages. --debug-info to enable them
  • Set the number of threads per device --device-gpu-threads
  • Per line ok/ko state message added
  • Force GPU processing to stop when connection with stratum server is lost
  • Time to wait before reconnecting configurable: -R/--retry-pause parameter added
  • Added extra error messages and minor fixes
