From our team to yours, now you too can experience the technology that sets Marathon apart.
MARAFW is custom firmware designed to optimize the individual chip settings of Bitcoin miners, improving their performance and efficiency while stabilizing operations. It also allows for better power consumption management and greater control over the mining hardware.
MARAFW offers several key features to optimize Bitcoin miners: It increases hash rate while maintaining optimal efficiency, allows quick auto-tuning or manual customization of settings for targeted performance, and provides options for overclocking to boost bitcoin production or underclocking for peak efficiency. Additionally, MARAFW includes intelligent thermal protection to prevent overheating, thereby protecting the longevity of miners.
MARAFW supports most Antminer S19, S21, and T21 series. It works with all Bitmain stock control boards and the MARA UCB 2100. For power supplies, it supports any Bitmain stock PSU and third-party PSUs compatible with Bitmain's firmware. If you encounter compatibility issues, please contact our support team at
Supported Miners:
There are no limitations on which mining pools can be used with MARAFW. You can configure multiple pools using the dashboard or using common mining management tools such as Foreman or BTC Tools.
The installation procedure depends on the control board type. Xilinx, AMLogic, BeagleBone, and Cvitek boards can be updated over the air (OTA). Initially, our team must perform installations, which our support team can guide you through.SD card installations are an option for Xilinx and BeagleBone boards. Please follow our step-by-step guide or detailed instructions.
Note: Cvitek boards need a MARACV board installed first.
