The NerdOctaxe 3.1 ULTRA (Rev 3.1) is a compact, open-source SHA-256 home Bitcoin miner built for real ASIC performance in a desktop-friendly format. It delivers a hashrate of up to 12 TH/s while typically drawing around 180–200 W (depending on tuning), making it a strong option for users who want efficient, configurable Bitcoin mining at home.
Powered by 8× BM1370 ASIC chips (S21 Pro generation), the Rev 3.1 ULTRA features an upgraded 6-phase VRM and improved power delivery for stable operation at higher performance profiles. This design focus helps maintain consistent hashrate, better thermals, and reliable long-term operation when running 24/7.
Designed for practical everyday use, the miner uses dual-fan air cooling, supports Ethernet connectivity, and runs at around ~40 dB in typical conditions—quiet enough for many home setups compared to full-size industrial miners. Depending on the selected profile, power can reach up to ~240 W, but the key advantage is its ability to be tuned for the best balance between hashrate, efficiency, and temperature.
A key highlight of the NerdOctaxe 3.1 ULTRA is its combination of up to 12 TH/s, tunable sub-250 W operation, and an open-source hardware ecosystem, making it an ideal choice for enthusiasts who want a powerful “desktop ASIC” for Bitcoin mining without the footprint and power draw of large miners.
