FAQ
What algorithm does the Antminer S21 Pro use?
The S21 Pro mines using the SHA-256 algorithm, compatible with Bitcoin (BTC) and other SHA-256-based cryptocurrencies.
What is the hash rate and power consumption?
It delivers a maximum hash rate of 234Th/s at 3,510W power draw, with an efficiency of 15J/Th.
How loud is the Antminer S21 Pro?
The operational noise level is 76dB—recommended for industrial settings or soundproofed spaces.
Does it include cooling fans?
Yes, it has four high-speed fans for efficient heat dissipation.
Where should I place the miner for optimal performance?
Install it in a well-ventilated area with stable airflow to prevent overheating.
Can I underclock the S21 Pro to save energy?
Yes, but doing so will reduce hash rate. Bitmain’s firmware allows tuning for efficiency.
Is the S21 Pro profitable in 2024?
The miner uses an RJ45 Ethernet (10/100M) connection to link to mining pools. A stable network ensures efficient communication for submitting hashes and receiving new mining tasks.
