NerdQaxe++ Rev6 Review
The NerdQaxe++ Rev 6 (often written NQ++ Rev 6) is an open‑source, quad‑chip SHA‑256 solo miner designed for home desks and small rooms. It delivers ~6.0–6.5 TH/s at roughly ~100–105 W in typical profiles, thanks to four Bitmain BM1370 (S21 Pro‑class) ASICs, an upgraded XT30 power input, thicker copper traces, and a spring‑mounted heatsink. In short: a compact, Wi‑Fi‑enabled solo miner with serious hashrate for its size.
Pros:
- High hashrate for home: ≈6 TH/s at ~102 W (≈ 16–17 J/TH typical).
- Open‑source hardware/firmware; source files linked from product page.
- Wi‑Fi + web UI; onboard 1.9" LilyGO display for live hashrate/temps.
- Improved power path: XT30 connector, thicker copper, cooler VRM temps.
Cons:
- Solo = lottery: payouts occur only if you find a block. Pools are steadier.
- Fan tone depends on setup (80/120 mm options). No official dB spec; room acoustics matter.
- Availability: primarily sold by one retailer; batches can sell out quickly.
If you prefer plug‑and‑play quiet heating with mining, compare with our Avalon Nano 3S review. For ultra‑low‑power learning at ~20–35 W, see Bitaxe Gamma.
Do not confuse this with earlier 4.8 TH/s versions of the NerdQaxe++ (2024‑era). This review covers the Rev 6 (2025) unit rated around 6 TH/s @ ~102 W. See details on the official product page.
Key Takeaways
- Throughput: ~6.0–6.5 TH/s in typical Rev‑6 profiles (see product table).
- Power: ~100–105 W (measured examples 6 TH/s @ 103 W → 17.2 J/TH).
- Efficiency class: ≈15–17 J/TH depending on clock/voltage and fan setup.
- Thermal/power upgrades: XT30 input, thicker copper, fuse‑free design → steadier OC.
- Best for: hobbyist solo‑lottery mining with open‑source flexibility.
Technical Specifications
| Item | Spec |
|---|---|
| Algorithm | SHA‑256 (BTC only) |
| ASICs | 4 × BM1370 (S21 Pro‑class) |
| Hashrate (typical) | ~6.0–6.5 TH/s |
| Power (typical) | ~100–105 W @ wall (kit/ambient variance) |
| Efficiency (math) | ≈15–17 J/TH (e.g., 6 TH/s @ 103 W → 17.2 J/TH) |
| Networking | Wi‑Fi (web UI) |
| Display | ~1.9″ LilyGO LCD (stats/price/network) |
| Power input | 12 V DC (XT30), typical bundle 12.4 V / 10 A PSU |
| Cooling | 80 or 120 mm fan path (varies by kit); spring‑mounted heatsink |
| What’s in box | Assembled miner, 12.4 V / 10 A PSU, stand, quick‑start card (per product page) |
Examples: 6 TH/s means 6 trillion SHA‑256 guesses per second. ~102 W is like a small desktop PC on light load. J/TH (joules per trillion hashes) — lower is better.
Performance, Noise & Heat
Solo Satoshi publishes a simple two‑point profile for Rev‑6:
| Freq / Core V | Hashrate | Power | Efficiency | Notes |
|---|---|---|---|---|
| 600 MHz / 1.150 V | ~4.82 TH/s | ~70.6 W | ~14.7 J/TH | Cool/quiet baseline |
| 800 MHz / 1.250 V | ~6.0 TH/s | ~103 W | ~15.7 J/TH | Typical Rev‑6 setting |
These figures come from the product page’s spec table/screenshots. Real‑world results vary by ambient temp, fan, and PSU quality. Expect a low, broadband fan whoosh from 80/120 mm fans (no official dB figure). Place the unit on a hard surface and keep an open exhaust path to reduce tonal resonance.
Heat output (rule‑of‑thumb): 1 W ≈ 3.412 BTU/h → ~102 W ≈ ~349 BTU/h — noticeable warmth, but not a room heater. If you want heater‑level warmth, see Avalon Nano 3S (140 W).
Electricity cost examples (24 h, continuous @ 102 W):
- €0.10/kWh →
€0.24/day (€7.34/month) - €0.20/kWh →
€0.49/day (€14.69/month) - €0.30/kWh →
€0.73/day (€22.03/month)
Formula: kWh = (Watts ÷ 1000) × hours. See kilowatt‑hour.
Setup & Pooling (quick start)
- Place & power: Keep the exhaust clear. Use the included 12.4 V / 10 A PSU (XT30 lead). Avoid thin/long DC cables.
- Connect: Join the miner to Wi‑Fi via the web UI (captive portal style). If you need wired stability, use a small Wi‑Fi‑to‑Ethernet bridge.
- Pool or solo: New users should start with a mining pool (steady sats). Solo is lottery‑style; consider https://ckpool.org or https://solopool.org with caution.
- Example pool string:
stratum+tcp://pool.example.com:3333
Username:bc1q...youraddress.worker1(Bech32)
Password:x(or pool‑specific). - Tuning: Increase frequency/voltage cautiously (e.g., 600 → 800 MHz). Watch temps, HW errors, and stale shares. Stop at signs of throttling/instability.
- Safety: This is a continuous‑load device. Use proper outlets, keep dust off the heatsink/fan, and check the XT30 connection is snug.
Docs & source: The product page links to source files on GitHub (open‑source hardware/firmware) and includes setup/OC videos.
Who Should Buy the NerdQaxe++ Rev 6?
- Solo‑curious hobbyists wanting real BTC mining at home without warehouse noise.
- Tinkerers who appreciate open‑source hardware and visible performance metrics.
- Users who want more TH/s than single‑chip boards but still desktop‑class power draw.
If you value ultra‑low power and silence above all, consider Bitaxe Gamma (~1.2 TH/s @ ~20 W). If you want heater‑plus‑miner comfort, see Avalon Nano 3S.

Verdict
NerdQaxe++ Rev 6 is a quad‑chip, open‑source solo miner that hits ~6 TH/s on ~100 W—a compelling middle ground between tiny single‑chip miners and louder, hotter “heater miners.” Treat it as a lottery‑style desktop unit with lots of tweakability and a clean web UI. If you’d rather have ultra‑low power (learning) or heater‑level warmth, the Gamma or Nano 3S may fit better.
FAQ's
Is NerdQaxe++ Rev 6 profitable?
Not at typical residential tariffs; think learning + decentralization + lottery.
How loud is it?
Depends on the fan (80/120 mm) and room acoustics. Expect a low fan whoosh rather than a server‑style whine.
Can I solo‑mine with it?
Yes, but solo is lottery—you only get paid if you find a block. Prefer a pool for steady sats.
Does it include a PSU?
The Solo Satoshi bundle includes a 12.4 V / 10 A PSU and stand (check the product page).
Ethernet support?
The Rev‑6 focuses on Wi‑Fi; use a small Wi‑Fi‑to‑Ethernet bridge if you require wired‑like stability.
