Frequently Asked Questions

Common questions about custom Antminer firmware

What is custom Antminer firmware?

Custom Antminer firmware is optimized software that replaces the stock firmware on your ASIC miner. It unlocks features like autotuning, overclocking, and undervolting to increase hashrate by 10-25% while reducing power consumption.

Is custom firmware safe for my miner?

Yes, our firmware is thoroughly tested and used by thousands of miners worldwide. It includes safety features like temperature monitoring and automatic shutdown protection. Always backup your original firmware before upgrading.

Which Antminer models are supported?

We support all major Antminer models including S21, S21 XP, S21 Pro, T21, S19 XP, S19 XP+, S19j Pro, S19k Pro, S19 Pro, S19j+, T19, and many more. Check the download table for the full list.

How do I install custom firmware?

Download the firmware for your model, access your miner's web interface, go to System → Upgrade, upload the firmware file, and wait for the installation to complete. The miner will reboot automatically.

What is the difference between Install and Update firmware?

Install firmware is for miners running stock firmware - it performs a clean installation. Update firmware is for miners already running our custom firmware - it preserves your settings while updating to the latest version.

Supported Antminer Models

Our custom firmware supports a wide range of Bitmain Antminer ASIC miners. Download optimized firmware for your specific model to unlock maximum performance.
