The firmware from is available for download free of charge, but it has a Dev Fee of 1.3% -2% (mining is not interrupted, the dev fee works parallel to the main mining). The firmware from makes it possible (with the same consumption as standard firmware from Bitmain) to get more computing power and extend the life of AntMiner 5 times due to the tuning of each chip separately.

AntMiner s9 / s9i / s9j firmware from fits all models. The first custom firmware with AsicBoost S9 saves up to 250W on pools that support AsicBoost technology (slushpool, antpool,, f2pool and others).

The design is made as similar as possible to the original one for more convenient use.

The firmware is installed in a standard way.

The firmware for S9 / S9i / S9j with control of each hashboard’s frequency, voltage and overclocking templates up to 18 + TH in the air and 19-22TH in immersion cooling. (Be careful, the overclocking requires a more powerful power supply. You can use 2 standard power supplies or 3 standard power supplies (1600W) for 2 Antminers – You must not connect one hashboard to two different power supplies!

  1. Fan check disable for immersion into the immersion cooling.
  2. Manual change of the fan speed in % or auto.
  3. Enable or disable the AsicBoost feature.
  4. Enable or disable low-noise fan auto mode.
  5. Change the frequency of all hashboards.

  7. Change the frequency of each hashboard individually.
  8. Change the Voltage of all hashboards.
  9. Watchdog - reboot when reaching the set temperature.
  10. Watchdog - restart when the hashrate drops.
  11. Reset.
  12. Save and apply.

- The Watchdog function allows you to automatically configure a reboot when the hashrate drops and when the set temperature is reached.

  1. Auto tuner profiles depending on power consumption.
  2. Available in Manual - minimum frequency value. At this value the Auto tuner finishes tuning.
