NerdQX | 8 TH/s

The NerdQX, labelled NerdQX-8.1T on delivery, is an open-source Bitcoin miner for the home in the upper middle class. Four BM1370 ASICs deliver around 8 TH/s at about 140 W, the firmware is AxeOS, the connection runs over 2.4 GHz Wi-Fi and a USB-C port is present. As with every device in this family, you enter pool, worker and Bitcoin address yourself, and nobody settles accounts on your behalf.

Power draw sits at around 140 W, which works out to roughly 17 J/TH and about €28 of electricity a month at €0.28/kWh in continuous operation. Cooling runs through a heatpipe heatsink with a 120 mm front and a 90 mm rear fan – in operation the device stays at around 38 dB. A colour display on the device shows hash rate and temperature without opening a browser. Plan for this all the same: a miner in this class needs more air and a better location than a 1.3 TH/s device.

In solo mining, all that counts is how many tickets you throw into the draw. At around 8 TH/s that is roughly six times as many as with a Bitaxe in the 1.3 TH/s class. If one of them hits, the full block reward of currently 3.125 BTC plus transaction fees goes to your own address, undivided and without an intermediary. It remains a lottery with very long odds, as our solo mining guide explains. The certain contribution is the other one: your device verifies transactions and helps secure the network.

• More hash rate without a rack: around 8 TH/s in a device meant for a flat, an office or a homelab, not for a mining container.
• Familiar operation: AxeOS in the browser, exactly as on the smaller Bitaxe and Nerdaxe models. If you already run one, there is nothing new to learn.
• No middleman for your hash rate: pool, worker and Bitcoin address are yours. There is no statement you cannot verify yourself.
• Delivered ready to run: miner, power supply, stand and quick start guide are included. From you come a socket, Wi-Fi and an address.

The family is graded by hash rate, and the NerdQX fills the gap in the middle. Below it sits the NerdQaxe++ with around 4.8 TH/s at roughly 80 W, above it the NerdOctaxe with around 12 TH/s at roughly 200 W. In electricity at €0.28/kWh that is about €16 and about €40 a month respectively. The NerdQX sits exactly between them at about 140 W and roughly €28 of electricity a month.

Efficiency stays on the family level: around 17 J/TH, practically level with the NerdQaxe++ and NerdOctaxe. You are choosing the hash rate step alone – efficiency and handling are the same across all three.

Even on the larger device the setup stays the same: position it, join Wi-Fi, enter the pool.

For home miners who have already run one or two smaller devices and now want more hash rate without moving to industrial hardware. And for tinkerers: hash rate, temperatures and the fan curve are all exposed in AxeOS, and frequency and voltage are yours to set.

It is less of a fit as a first step into mining – for that it is oversized; a device in the 1.3 TH/s class at about €3 of electricity a month is enough for that.

The box contains the miner, a 12.4 V / 20 A power supply, a 3D-printed stand and a quick start guide. From you come a socket, 2.4 GHz Wi-Fi, a browser and your own Bitcoin address.

Plus a location where a running fan bothers nobody and warm exhaust air can escape. In continuous operation it is worth watching the temperature readout in AxeOS for a few days and setting the fan curve afterwards.

With the NerdQX it is less about accessories on the device and more about its surroundings: cooling, clean power and the question of what your hash rate works against.

• Cooling for heatsinks and quieter fans. Check dimensions and mounting against your device first.
• Power supplies, mounts and small parts that keep the setup tidy in continuous operation.
• Bitcoin nodes if your hash rate should eventually point at your own infrastructure.

Around 8 TH/s at about 140 W, AxeOS and your own address: the NerdQX is the step for everyone who has outgrown the 1.3 and 4.8 TH/s classes and still wants a device that can live at home.
