The BM1370 Chip. Open-Source. On Your Desk. 8 TH/s.
The NerdQX is a fully open-source Bitcoin ASIC miner built around four BM1370 chips — the exact same silicon that powers Bitmain's flagship Antminer S21 Pro — delivering 6.3 TH/s at default settings and up to 8 TH/s when overclocked via the AxeOS web interface. It's a fundamentally redesigned evolution of the NerdQAxe++: horizontal PCB architecture, dedicated VREG heatsink, industrial XT60 power connector, Arctic pre-installed fans, liquid cooling compatibility, and a 15A visible fuse with hardware protection built in. At under 180W, it runs quietly enough to live on your desk permanently — and every component, schematic, and line of firmware is publicly available on GitHub.

What open-source actually means here
This isn't open-source as a marketing term. The full PCB schematics, Gerber files, and firmware are publicly available on GitHub. Anyone can inspect the design, modify the firmware, build their own, or contribute improvements. The NerdQX runs AxeOS (ESP-Miner), the same open-source firmware used across the Bitaxe/Nerd ecosystem — which means regular community-driven firmware updates, a thriving Discord and Reddit community, and comprehensive documentation.
For technically curious buyers, the NerdQX is as much a hardware platform as it is a miner. You can customise clock speeds, voltage, fan curves, and pool configuration entirely through the browser-based AxeOS dashboard — no proprietary software, no locked firmware, no vendor lock-in.
Default vs overclocked — two ways to run it
Default (600 MHz)
Hashrate~6.3 TH/s
Power draw~110–130W
Noise<40 dB
ASIC tempWell within limits
Maximum stability. Set it, forget it. Best for 24/7 unattended solo mining.
Overclocked (1000 MHz)
Hashrate8–8.1 TH/s
Power draw~150–160W
Noise40–45 dB
Efficiency17.86 J/TH
Push hashrate via AxeOS in 25–50 MHz increments. Never exceed 75°C ASIC temp. Monitor before tuning further.
The block you're hunting
Solo mining at 8 TH/s is lottery mining — the odds are low, but the prize is the entire block reward: currently 3.125 BTC per block. In January 2025, a solo miner running six NerdQAxe++ units found block #920,440 and collected the full reward of approximately $342,000 USD at the time. Six open-source miners on a desk. That's the proposition. The NerdQX gives you 50% more hashrate per unit than the NerdQAxe++ — and every TH/s is another ticket.
NerdQX vs LG07 — both solo miners, different audiences

The LG07 is a DOGE/LTC lottery miner at minimal cost. The NerdQX is a Bitcoin solo miner for people who want serious hashrate, open-source firmware control, and the ability to customise their setup. Different algorithms, different audience, complementary products.

What makes the NerdQX different from the NerdQAxe++
Horizontal PCB Architecture
Completely rethought board layout for better airflow, thermal distribution, and component accessibility vs the NerdQAxe++ vertical stack.
Dedicated VREG Heatsink
Voltage regulator heat is the primary cause of premature board failure. The NerdQX heatsinks the VREG directly — most alternatives don't.
XT60 Industrial Power Connector
15A-rated XT60 replaces lighter-duty connectors used on earlier NerdQAxe revisions for safer sustained power delivery.
Arctic P9 + P12 Fans Pre-Installed
Premium quality-bearing fans arrive mounted and ready. No swapping, no sourcing — quieter and longer-lasting than generic fan options.
Liquid Cooling Compatible
Three PWM 4-pin fan headers and LGA115x footprint let you add a custom water loop without any board modification.
Hardware Safety — Triple Protected
15A visible fuse, reverse connection protection, and hot-swap short-circuit protection are all built in — features absent from budget alternatives.

Bitcoin solo mining block rewards are probabilistic — finding a block is not guaranteed and depends entirely on network difficulty and statistical luck. The NerdQX is designed for the enthusiast and hobby value of solo Bitcoin mining. Overclocking increases hashrate but also power draw, heat, and component wear — overclock only within the AxeOS guidelines and never exceed 75°C ASIC temperature. MinerHub does not guarantee mining returns of any kind. Electricity cost calculations are estimates. The 8 TH/s hashrate figure is achieved via overclocking at 1000 MHz; default settings produce ~6.3 TH/s. AU plug adapter may be required for the included PSU.
