Definition
Underclocking reduces the operating frequency of ASIC chips, resulting in lower hashrate but significantly reduced power consumption, heat output, and fan noise. When combined with undervolting, underclocking can transform a loud, power-hungry data center miner into a viable home mining device.
For home miners using Bitcoin space heaters, underclocking allows fine-tuning of heat output to match heating needs. This is a key technique for dual-purpose mining where the goal is both Bitcoin earnings and space heating.
In Simple Terms
Running mining hardware slower to reduce power, heat, and noise. Essential for home mining setups.
Running mining hardware at lower clock speeds than default to reduce power consumption, heat, and noise. Common for home mining applications.
