Overclocking, Underclocking & Autotuning

Custom firmware enables miners to adjust clock frequencies and voltages, allowing miners to optimize performance and efficiency. The main strategies are overclocking, underclocking and autotuning.

• Overclocking pushes the miner beyond its factory limits by increasing frequency or voltage, boosting hashrate and mining output. While this improves performance, it also increases power consumption, heat, and wear on the hardware—factors that can shorten lifespan and raise operating costs.

• Underclocking, by contrast, reduces frequency or voltage to lower power draw and heat output. Though it results in a lower hashrate, this trade-off can be worthwhile in high electricity cost environments, when hashprice is suppressed or when cooling is limited, helping extend hardware lifespan and improve efficiency.

• Autotuning automates performance optimization by dynamically adjusting settings like voltage, frequency, and fan speed. It uses real-time performance and temperature data to find the ideal balance between efficiency and output, minimizing manual intervention while maximizing results.

Together, these tools give miners more control over how their machines perform under varying conditions, allowing for tailored strategies that align with operational goals.

Each ASIC Model Requires New Custom Firmware Development

ASIC miner manufactures often release new models of mining hardware. New models require custom firmware development due to differences in design and functionality.

Each ASIC model utilizes distinct chips with unique voltage, frequency, and power efficiency characteristics. Additionally, hashboard architecture evolves between models, requiring customized drivers and control algorithms to ensure optimal performance. Different models also have power supply unit (PSU) with specific voltage regulators, necessitating firmware modifications for proper tuning and stability.

The firmware also differs per cooling mechanisms. Air-cooled miners rely on fan control algorithms, while immersion-cooled models eliminate fans altogether, requiring alternative temperature management strategies. Hydro cooled miners also demand specialized firmware to regulate coolant flow and temperature thresholds.
