Jasminer X16‑Q Review
The Jasminer X16‑Q is a quiet, apartment‑friendly Etchash/Ethash ASIC aimed at Ethereum Classic (ETC) (and Ethash‑family forks). It typically delivers ~1.95 GH/s (1950 MH/s) at ~620 W, with a listed noise of ~40 dB and simple Ethernet web UI. Think of it as the “set‑and‑forget” ETC box: far more performance than older X4 units, without the server‑room howl of GPU farms.
Pros:
- Quiet for its class: listed ~40 dB (office‑like tone) with integrated fans.
- Solid efficiency: ~0.32 J/MH (620 W ÷ 1950 MH/s). Pro variant improves to ~0.25 J/MH.
- ETC‑first with broad Ethash/Etchash coin support and ETC+ZIL options on compatible pools.
- Home‑friendly form factor: 3U‑style chassis, Ethernet setup; runs from standard 100–240 V AC PSUs.
Cons:
- Not ROI‑only: profitability depends heavily on power price and coin markets; treat as a quiet ETC stacker.
- Heat is real: ~620 W → ~2,115 BTU/h; plan airflow. (See heat & cost examples.)
- Ethernet‑only (most units): add a Wi‑Fi‑to‑Ethernet bridge if you can’t run cable.
Prefer lower power/noise? See our desktop Scrypt picks (e.g., Mini‑DOGE II) or our SHA‑256 mini‑rigs (e.g., Avalon Nano 3S) for different algorithms.
Key Takeaways
- Throughput & power: ~1.95 GH/s @ ~620 W → ~0.32 J/MH. Pro boosts to 2050 MH/s @ ~520 W (~0.25 J/MH).
- Noise: about ~40 dB ±10% (typical listings) — check placement/surfaces.
- Algorithm: Etchash (ECIP‑1099 “Thanos” Ethash variant) — designed for ETC security and smaller DAG growth.
- Modes: units support Efficiency / Balance / Performance profiles in firmware.
- Best use‑case: quiet, continuous ETC mining with straightforward Ethernet setup.

Plain‑English examples: 1.95 GH/s = 1,950,000,000 hashes/sec. 40 dB is like a quiet office. 620 W is similar to a small space heater on low.
Performance, Noise & Heat
Expect ~1.9–2.0 GH/s once warmed up, drawing ~620 W at the wall (firmware mode and PSU quality can shift a few watts). Noise is a soft, steady whoosh; tone depends on room acoustics. Placing the miner on a firm surface and keeping the rear exhaust unobstructed helps.
Heat output (rule‑of‑thumb)
1 W ≈ 3.412 BTU/h → 620 W ≈ ~2,115 BTU/h. Not a room heater, but you’ll feel warmth nearby.
Electricity cost examples (24 h, continuous @ 620 W)
- €0.10/kWh → ~€1.49/day (~€44.6/month)
- €0.20/kWh → ~€2.98/day (~€89.3/month)
- €0.30/kWh → ~€4.47/day (~€133.9/month)
Formula: kWh = (Watts ÷ 1000) × hours. See kilowatt‑hour.
Setup & Pooling (quick start)
- Place & power: Leave intake/exhaust clear. Verify PSU inclusion; most units are rated 100–240 V AC. Short, thick cables reduce voltage drop.
- Network: Connect Ethernet (RJ45) to your router/switch. If cable is impossible, use a small Wi‑Fi‑to‑Ethernet bridge.
- Web UI: Open the device IP in your browser; set pool URL, wallet, and worker.
Example ETC pool string:stratum+tcp://etc.2miners.com:1010orstratum+tcp://etcf.flexpool.io:8008
Username: your ETC address (e.g.,0x...) or pool account
Password:x(or as required).
Reputable options: https://2miners.com (ETC), https://flexpool.io (ETC), https://hiveon.net (ETC). - Firmware mode: Start with Balance; try Efficiency for lower power or Performance for max hashrate.
- Verify & monitor: After 5–10 min, hashrate stabilizes. Watch Rejected/Stale shares; if they rise, improve network or change pool server.
Merged mining tip: Some pools support ETC + ZIL cycles; follow each pool’s setup guide for ZIL wallet switching.
Who Should Buy the Jasminer X16‑Q?
- Home or office users wanting quiet ETC mining with minimal fuss.
- Upgraders from X4‑class who want ~2× hashrate at similar noise.
- Buyers who value lower noise over chasing absolute top efficiency (that’s the X16‑Q Pro).
If your priority is best efficiency, compare with the X16‑Q Pro. If you need a lower upfront price, consider the X16‑QE or older X4‑Q.

Verdict
The X16‑Q cleanly hits the home ETC niche: ~1.95 GH/s at ~620 W, ~40 dB class noise, and a straightforward web UI. If you want quiet, continuous mining with minimal setup, this is an easy recommendation. For best‑in‑class efficiency, look at the X16‑Q Pro; for lower upfront cost, consider X16‑QE or X4‑Q.
FAQ's
Is the X16‑Q profitable at home rates?
It depends on ETC price and your €/kWh. Budget ~14.9 kWh/day before pool fees.
Is it truly quiet?
Listings quote ~40 dB, but tone varies with room/surfaces. Place on a firm, open surface.
Wi‑Fi built‑in?
Most units are Ethernet‑only; add a Wi‑Fi bridge if needed.
Can it mine ETH?
Ethereum (ETH) moved to PoS. You mine ETC and compatible Ethash/Etchash forks; some pools support ETC+ZIL.
