Firmware for Bitmain Antminer BTC & LTC Miners

We are an official Vnish partner and authorized distributor of custom firmware for Bitmain Antminer models that mine BTC and LTC. This partnership ensures reliable, fully supported firmware that helps optimize performance, reduce power consumption, and unlock advanced features such as per-chip tuning and watchdog control.

It allows you to fine-tune all performance parameters, optimize watt-per-terahash ratio, and keep your miner running even if only one hashboard is operational — something stock firmware doesn’t support.

Please note that this firmware includes a 3% developer fee, which is easily offset by the electricity savings. Read more about the benefits here.

Disclaimer: We are not responsible for any issues resulting from firmware installation if it is performed by third parties or not according to our instructions. Installing third-party firmware may void your factory warranty.

If you want us to take full responsibility for firmware performance and keep your original warranty valid, we offer Remote Miner Diagnostics & Firmware Upgrade — a professional service performed by our certified team.

Bonus: Run our firmware for over 30 days and receive a 5% discount on repair services^*.

For optimal use, please ensure you choose the correct firmware version that matches your Antminer model.
