NerdAxe, NerdQAxe++ and NerdOctaxe Miners

One chip, four chips or eight

The name tells you the size of the board: a NerdAxe carries one chip, a NerdQAxe four and a NerdOctaxe eight. All of them run AxeOS (the NerdAxe Gaia Copper Pro runs NerdOS), show their statistics on a colour display and connect to 2.4 GHz Wi-Fi.

• NerdAxe Gaia: the new BM1373 chip, around 2.6 TH/s at 25 W. At about 10 J/TH the most efficient miner in our range.
• NerdAxe Gaia Copper Pro: the same BM1373 under a copper cooler with two heat pipes, around 3 TH/s at 33 W from the factory.
• NerdAxe Gamma: one BM1370, 1.2 TH/s at 17 W, the compact entry model.
• NerdQAxe++: four BM1370 chips, 4.8 TH/s at 70 W, the four-chip board most people pick.
• NerdQAxe Copper Pro: the same four chips on solid copper, 4.8 TH/s at 80 W, built for people who tune frequency and voltage themselves.
• NerdQAxe++ Hydro: four BM1370 chips in a closed water loop, about 6 TH/s at 100 W.
• NerdQX: around 8 TH/s at 140 W, under a tower heatsink with a 120 mm fan.
• NerdOctaxe Rev 3.1: eight BM1370 chips, 12 TH/s at 200 W. The strongest air-cooled miner in our range.
• NerdOctaxe Hydro: eight BM1370 chips under water, 14 TH/s.

How to choose

Power and heat

Every watt ends up as heat in the room. A single-chip NerdAxe uses 12 to 24 kWh a month, a NerdQAxe++ about 50 kWh, a NerdOctaxe about 145 kWh. Look at your tariff first, then at the hashrate.

Noise

Fans work harder as the power goes up. The NerdQX runs at about 38 dB. The Hydro models move their heat into a closed water loop, which keeps them quiet at high hashrate.

First miner or more hashrate

For a first miner the NerdAxe Gamma or the Gaia is the easy start: small, fine on a desk, set up in ten minutes. The four and eight chip boards make sense once you know you want more hashrate and have a place where heat and fan noise bother nobody.

Setup and accessories

The NerdAxe Setup Guide covers the single-chip models, the NerdQAxe Setup Guide the NerdQAxe and NerdOctaxe boards. Cases and stands for these boards are in Accessories. All miners side by side: miner comparison.
