NerdMiner NerdOCTAxe Rev 3.1 Description
The NerdMiner NerdOCTAxe Rev 3.1 is a compact SHA-256 ASIC miner developed for Bitcoin solo mining, pool mining, technical learning, and home-based mining experiments.
Built with eight BM1370 ASIC chips, the miner delivers up to approximately 12 TH/s while consuming around 240W under typical operating settings. Its compact design and relatively low total power demand make it more practical for hobbyists than full-size industrial Bitcoin miners.
The NerdOCTAxe is designed for users who want hands-on experience with ASIC mining without installing a multi-kilowatt mining machine. It can be used to participate in solo-mining pools or compatible SHA-256 mining pools, depending on the firmware and pool configuration.
NerdOCTAxe Rev 3.1 vs NerdOCTAxe 9.6 TH/s
The NerdOCTAxe Rev 3.1 provides approximately 25% more hashrate, while the 9.6 TH/s model consumes less power and offers better energy efficiency. The better option depends on electricity cost, available cooling, purchase price, and whether the user prioritizes higher hashrate or lower operating power.
