ANTMINER D3 profitable again!

custom FIRMWARE (no Fee from mining!) for download

The Antminer D3 is a cryptocurrency mining hardware for DASH developed by Bitmain. It was released in 2018 and was one of the most powerful DASH miners on the market at that time. However, due to the decrease in DASH price and increasing mining difficulty, the D3 has become less profitable in recent years.

Profitable custom Firmware D3

However, the situation has changed with the advent of custom firmware. This firmware, developed by independent developers, allows the Antminer D3 to mine with a 20-30% increase in performance. This means that even an older D3 can be profitable again if used with custom firmware.

Advantages of Custom Firmware D3

Here are some of the main advantages of using custom firmware on the Antminer D3:

  • Increased hashrate: You get 20-30% more hashrate, which will increase your mining profits.
  • Reduced power consumption: Custom firmware can optimize power consumption and thus reduce operating costs.
  • Better stability: Custom firmware can improve the stability and reliability of the miner.

Disadvantages of Custom Firmware

It is important to note that using custom firmware also has its drawbacks:

  • Loss of warranty: Using custom firmware will most likely void the warranty on your Antminer D3.
  • Technical knowledge: Installing and configuring custom firmware can be technically challenging.
  • Risk of damage: Incorrect installation of custom firmware can damage your miner.


The following table compares the Antminer D3 with and without custom firmware:

Feature Stock Firmware Custom Firmware
Hashrate 19.5 GH/s 25.3 GH/s
Power consumption 1200 watts 1200 watts
Noise level Loud Moderate
Custom firmware Not available Available
Hashrate increase N/A 20-30%


Custom firmware for the Antminer D3 can be a great way to revive an old miner and mine DASH profitably. However, it is important to weigh the pros and cons above and make sure you are aware of the risks before proceeding with the installation of custom firmware.
