The NerdQAxe Phenomenon
On April 7, 2026, a single NerdQAxe++ unit found Block #944,078, earning its operator 3.132 BTC—approximately $342,000 at the time. A few months earlier, a Solo Satoshi customer running six NerdQAxe++ Rev 6 units found Block #920,440, walking away with over $342,000. Combined, NerdQAxe++ units have now confirmed three Bitcoin block finds with total rewards exceeding $560,000.
This is the reality of open-source solo mining in 2026. While industrial ASIC farms dominate the Bitcoin network, a small but growing community of hobbyists and enthusiasts are proving that desk-sized miners can still hit the lottery.
The NerdQAxe family represents the most powerful generation of open-source, standalone Bitcoin solo miners available today. Built on the same BM1370 silicon that powers Bitmain’s flagship Antminer S21 Pro, these compact devices deliver industrial-grade efficiency in a palm-sized, whisper-quiet package.
This guide covers everything you need to know: what the NerdQAxe is, the top five models available in 2026, how to overclock them safely, how to set them up, and whether solo mining with one actually makes sense.
What Is a NerdQAxe Bitcoin Solo Miner?
The NerdQAxe is an open-source, multi-chip SHA-256 ASIC miner designed specifically for solo Bitcoin mining. It is part of the broader open-source mining movement that began with the Bitaxe project—a community-driven effort to democratize Bitcoin mining by putting industrial-grade ASIC silicon on accessible, open-source boards.
The Core Concept
The NerdQAxe takes the Bitaxe philosophy and scales it up. While a single-chip Bitaxe Gamma runs one BM1370 ASIC at roughly 1.2 TH/s, the NerdQAxe++ aggregates four BM1370 chips on a single board to deliver approximately 4.8 TH/s at stock settings. The NerdOCTAxe takes this further with eight chips for approximately 9.6 TH/s.
The name “NerdQAxe” breaks down simply:
-
Nerd: A nod to the community-driven, tinkerer-friendly nature of the project
-
Q: Quad (four ASIC chips)
-
Axe: From the Bitaxe project, acknowledging its roots
The Silicon: BM1370
The heart of the NerdQAxe++ is the BM1370 ASIC—the same chip used in Bitmain’s Antminer S21 Pro, S21+, and S21+ Hydro. These are 3nm chips with top-tier efficiency around 15-17 J/TH, representing the latest generation of Bitcoin mining silicon.
Each BM1370 chip typically delivers around 1.2 TH/s per die. Four chips working in parallel produce 4.8 TH/s at stock settings, consuming just 72W at 15 J/TH efficiency.
Open-Source Philosophy
The NerdQAxe is fully open-source. Schematics, PCB layouts, firmware, and bill of materials are all publicly available. This means:
-
Verifiable hardware: Anyone can audit the design
-
No vendor lock-in: You control the firmware, not a manufacturer
-
Community innovation: Improvements are shared and iterated upon
-
No remote kill switches: Unlike industrial miners, no one can shut your machine down remotely
The miner runs AxeOS (ESP-Miner firmware) on an ESP32-S3 controller, featuring a LILYGO T-Display S3 color LCD for real-time stats and WiFi 2.4GHz connectivity. No computer needed—just plug in power, configure your pool and Bitcoin address, and start hashing.

How to Overclock Your NerdQAxe?
Overclocking is one of the main reasons enthusiasts choose the NerdQAxe++. However, it requires careful attention to hardware and thermal management.
The Physics of Overclocking
The BM1370 chips are incredibly efficient, typically delivering around 1.2 TH/s per die at 15-17 J/TH. In a standard NerdQAxe++ configuration, four chips produce 4.8 TH/s at 76-90W.
However, power consumption does not scale linearly with clock speed. When you increase frequency and core voltage, current draw spikes exponentially. Most standard NerdQAxe++ units ship with a 12V/10A (120W) power brick. When overclocked BM1370 chips demand massive transient current spikes, total system draw can exceed 120W, triggering the onboard over-current protection (OCP).
What You Need Before Overclocking
Power Supply: The stock 12V/10A PSU cannot handle overclocking. Upgrade to a Mean Well RSP-350-12 (350W, 12V) or similar to support approximately 110-115W for moderate overclocks.
Fuse: The stock 8A fuse fails above approximately 100W. Swap it for a 12A or 15A Littelfuse 451 NANO2 series.
Power Cable: Use a 16 AWG cable for approximately 110-115W overclocks. For 15A fuses, go with 14 AWG.
Cooling: The stock Thermalright AXP90 X36 cooler works up to approximately 100W but struggles beyond. Upgrade to the AXP90 X47 and consider a 3D-printed HELIX shroud with a 120mm fan to keep ASIC below 60°C.
Thermal Paste: Apply fresh thermal paste (MX-6 works well) when upgrading coolers.
Firmware Considerations
Starting from firmware version V1.0.35, the NerdQaxe++ enforces a firmware-level current limit of 100A. Ensure you are running the latest firmware from the Bitaxe GitHub for stability and overclocking support.
Step-by-Step Overclocking Guide
Step 1: Baseline Testing
Run the NerdQAxe++ at stock settings and track hashrate, ASIC temperature, and power usage via the LILYGO T-Display S3 or AxeOS. Connect to a mining pool and stress test for 1-2 hours to confirm stability.
Step 2: Access AxeOS Advanced Settings
Connect to the NerdQAxe++ via WiFi and log into the AxeOS web interface. To expose frequency and voltage fields, append ?oc to the end of your settings URL (e.g., http://192.168.1.50/#/settings?oc).
Step 3: Set a Baseline Voltage
For the BM1370, a solid starting point is 0.78V core voltage. Set your fan to Automatic Fan Control or 100% manual if you are pushing limits.
Step 4: The Frequency Climb
Start at 600 MHz and raise by 25 MHz increments (e.g., to 625 MHz, then 650 MHz). Input your new value in Settings > Frequency, save, and restart.
Step 5: Stability Testing
After each change, let the miner run for at least 20-30 minutes. Monitor:
-
Hashrate: Should remain stable (e.g., within ±250 GH/s)
-
HW Errors: A continuous stream indicates instability
-
Temperature: Critical—keep ASIC below 60°C
Step 6: Voltage Correction
If the miner crashes or hash rate drops:
-
Increase Core Voltage by small steps (e.g., 20-25mV)
-
Test again for stability
Keep voltage as low as possible to minimize heat.
Step 7: Fine-Tuning
A typical overclocking path might look like:
-
Stock: 4.8 TH/s at 600 MHz
-
Step 1: 625 MHz → ~5.1-5.3 TH/s
-
Step 2: 650 MHz → ~5.5-5.8 TH/s
-
Step 3: 675 MHz → ~6.0-6.3 TH/s
-
Step 4: 700 MHz → ~6.2-6.5 TH/s (requires upgraded cooling)
The NerdQAxe++ Rev 6.1 can typically push from 600MHz stock to 700-750MHz.
Common Overclocking Issues and Fixes
Issue: “Current Protection” Warning
Cause: The onboard Texas Instruments INA260 power meter detects abnormal load exceeding 120W and triggers over-current protection.
Fix: Upgrade your power supply (to 200W+), replace the 8A fuse with a 12A or 15A fuse, and ensure your power cable is adequately rated.
Issue: Thermal Throttling
Cause: ASIC temperature exceeding safe operating limits (typically >70-75°C).
Fix: Upgrade to a better cooler (AXP90 X47), apply fresh thermal paste, improve case airflow, or reduce frequency/voltage.
Issue: Hashrate Instability
Cause: Voltage too low for the frequency setting.
Fix: Increase core voltage by 20-25mV increments.
Issue: System Crashes
Cause: Overclock too aggressive for the silicon quality (silicon lottery).
Fix: Reduce frequency by 25MHz or increase voltage. Some chips simply cannot sustain high overclocks.

What is the probability of you winning a prize using NerdMiner?
Let’s be honest about the numbers.
Bitcoin Network Stats (August 2026)
| Metric | Value |
|---|---|
| Network Hashrate | ~868 EH/s |
| Difficulty | ~127 trillion |
| Block Reward | 3.125 BTC |
| Blocks per Day | ~144 |
NerdQAxe++ Odds
A 6 TH/s NerdQAxe++ represents approximately 0.00000069% of the network hashrate (6 TH/s ÷ 868,000,000 TH/s).
Probability of finding a block:
-
Per day: ~0.00000069% × 144 blocks = ~0.0001%
-
Per year: ~0.033%
-
Over 5 years: ~0.16%
As one guide puts it: “A NerdQAxe++ at 4.8 TH/s has roughly a 0.45% chance of finding a Bitcoin block over 5 years”. At 6 TH/s, the odds are slightly better, but still extremely long.
Alternative: Mining BCH2
Some solo miners point their NerdQAxe at smaller SHA-256 chains like BCH2 (Bitcoin Cash 2) where the difficulty is lower. On BCH2, a NerdQAxe++ might expect a block approximately every 11 years—still long, but significantly better odds than Bitcoin.
The Bottom Line
Solo mining with a NerdQAxe is not a rational profit-maximizing strategy. It is a lottery ticket with very long odds and a very large payout if you win. As one analyst notes: “Pure profit-seekers should usually avoid it and Bitcoin enthusiasts almost universally enjoy it”.
