Four Ways MARAFW Transforms Your Fleet

Optimize Performance

Boost hashrate while maintaining peak efficiency. MARAFW extracts maximum output from every hashboard without compromising hardware lifespan.

Auto-Tune Like Never Before

Set your target — performance, efficiency, or balanced — and let MARAFW optimize automatically. Results in minutes, not hours of manual tuning.

Overclock or Underclock with Ease

Need more hashrate? Push to 35% above stock. Prioritizing efficiency? Underclock to the sweet spot. One slider, full control.

Safeguard Your Miners

Intelligent thermal protection activates in seconds. MARAFW monitors temperature per-chip and adjusts frequency dynamically to prevent damage.
