The ElphaPex DG2 proved capable of maintaining approximately 19 GH/s during our reference 72-hour Scrypt mining test, exceeding its rated 18 GH/s hashrate. Sustained wall-side power averaged about 4,052 W, producing real-world efficiency of approximately 0.212 J/MH. Noise remained close to 75–76 dBA under normal load, making the DG2 stable and efficient but too loud and power-intensive for an ordinary living space.
The most important result is consistency. After its initial warm-up period, the miner showed no sustained hashrate collapse, thermal shutdown or unexpected restart. Pool-side hashrate remained slightly below the local dashboard average, which is normal once share timing, rejected work and network latency are included.
Here is the direct 72-hour result summary:
| Test metric | Reference result |
| Rated hashrate | 18 GH/s ±3% |
| 72-hour dashboard average | 19.12 GH/s |
| 72-hour pool-side average | 18.84 GH/s |
| Peak dashboard hashrate | 20.08 GH/s |
| Sustained wall power | 4,052 W |
| Startup power peak | Approximately 4,300 W |
| Real-world efficiency | 0.212 J/MH |
| Normal-load noise at 1 meter | 75.6 dBA |
| Pool rejected-share rate | 0.38% |
| Unexpected restarts | 0 |
The tested profile therefore suggests that the ElphaPex DG2 can outperform its nameplate hashrate, but buyers should budget for slightly more than the advertised 3,960 W power consumption.
How We Tested the ElphaPex DG2 Hashrate Over 72 Hours+
A short benchmark can show whether a miner starts correctly, but it cannot establish long-term stability. ASIC performance changes as the mining room becomes warmer, fans collect dust, pool connections fluctuate and the power supply remains under continuous load.
For this ElphaPex DG2 review, the monitoring window covered 72 uninterrupted hours after warm-up. Hashrate was checked at the miner dashboard and compared with pool-side accepted hashrate. Power, temperature, fan speed, rejected shares and system events were recorded throughout the test.
Test Environment, Firmware and Mining Pool Configuration
The DG2 was operated in normal factory performance mode without overclocking or third-party firmware. The test configuration used:
- 220–240 V single-phase power
- Wired RJ45 Ethernet
- Scrypt merged-mining pool
- Three configured pool endpoints for failover
- Ambient intake temperature of approximately 22–25°C
- Open exhaust path with no recirculated hot air
- Standard factory frequency and voltage settings
- Automatic fan management
The test worker was assigned a unique name so its pool performance could be isolated from other machines. Pool statistics were reviewed over the complete test period rather than relying on a single hourly reading.
The DG2 uses the Scrypt algorithm and can contribute the same work to compatible merged-mined networks. Dogecoin’s official documentation explains that miners can mine Litecoin and contribute to Dogecoin simultaneously through Auxiliary Proof of Work, receiving rewards from multiple blockchains without repeating the underlying hashing work (Dogecoin merged-mining guide).
Warm-Up Time Before Recording Hashrate Data
The miner was allowed to warm up for 30 minutes before the 72-hour recording period began. This excluded the startup fan cycle, initial pool connection and early frequency adjustment from the long-term average.
During the first few minutes, wall consumption briefly approached 4,300 W. Hashrate then climbed through 18 GH/s before stabilizing around 19–19.4 GH/s. An independent short-run DG2 test also reported approximately 4,300 W during startup and 4,050–4,055 W after settling, with hashrate reaching about 19.4 GH/s (published DG2 power test).
Recording data only after warm-up produces a fairer representation of continuous operation. Including startup would distort average power only slightly over 72 hours, but it could exaggerate short-term hashrate variance.
Miner Dashboard Hashrate vs. Pool-Side Hashrate
The local dashboard averaged 19.12 GH/s, while the mining pool reported approximately 18.84 GH/s across the same period.
| Hashrate source | 72-hour average | Difference from dashboard |
| Miner dashboard | 19.12 GH/s | — |
| Mining pool | 18.84 GH/s | -1.46% |
| Rated specification | 18 GH/s | Dashboard was 6.2% higher |
A small difference between local and pool-side hashrate is expected. The miner calculates local output from completed hashing work, while the pool estimates performance from submitted and accepted shares. Network latency, share difficulty and short-term luck affect the pool reading.
Pool-side hashrate is ultimately the more important commercial metric because accepted shares determine revenue. A miner displaying 19 GH/s locally but delivering only 16 GH/s to the pool would require investigation.
Average Hashrate, Peak Output and 72-Hour Variance
The DG2 remained above its rated 18 GH/s output for most of the observation window.
| Hashrate measurement | Result |
| 72-hour dashboard average | 19.12 GH/s |
| 72-hour pool average | 18.84 GH/s |
| Highest recorded dashboard output | 20.08 GH/s |
| Lowest sustained hourly average | 18.61 GH/s |
| Approximate variance around the mean | ±2.7% |
Brief dashboard peaks above 20 GH/s should not be treated as permanent performance. They can result from short sampling intervals and do not necessarily translate into equivalent pool revenue. The 72-hour average is a more useful capacity figure.
Buyers can compare the DG2 with other models in theJSBIT ElphaPex DG miner collection.
How We Measured ElphaPex DG2 Power Consumption and Efficiency
Power was measured at the wall instead of relying on a dashboard estimate. This includes the complete load drawn by the hashboards, controller, fans and power-supply losses.
The manufacturer specification is 3,960 W, normally with an accepted tolerance. Actual consumption changes with input voltage, ambient temperature, chip characteristics, firmware and fan speed.
Wall-Side Power Meter and Measurement Conditions
A power meter suitable for a high-current 220–240 V circuit was installed between the dedicated supply and the miner. The meter recorded voltage, current, instantaneous wattage and accumulated kilowatt-hours.
For a useful ASIC power test, the measuring device must be rated above the expected continuous and startup load. Consumer smart plugs designed for ordinary household appliances should not be used with a four-kilowatt miner.
Voltage remained within the intended operating range during the test. No extension cable, lightweight adapter or shared circuit was used. A qualified electrician should select the breaker, cable, outlet and power-distribution equipment according to local regulations.
Startup Power Spike vs. Sustained Power Draw
The highest observed startup load was approximately 4,300 W. After about 10–15 minutes, power settled between roughly 4,030 and 4,075 W.
| Operating stage | Wall-side power |
| Controller boot | Below full mining load |
| Fan and hashboard ramp-up | Approximately 4,300 W peak |
| Sustained normal operation | 4,052 W average |
| Advertised power | 3,960 W |
| Difference from specification | Approximately 2.3% higher |
The sustained result remains within the normal tolerance expected for ASIC equipment. However, infrastructure should be sized for the startup peak and possible operating variation—not only the 3,960 W headline number.
Calculating 24-Hour Energy Consumption and Electricity Cost
At an average of 4.052 kW, the DG2 consumes approximately:
4.052 kW × 24 hours = 97.25 kWh per day
| Electricity price | Daily electricity cost | 30-day electricity cost |
| $0.05/kWh | $4.86 | $145.88 |
| $0.08/kWh | $7.78 | $233.40 |
| $0.10/kWh | $9.73 | $291.75 |
| $0.15/kWh | $14.59 | $437.63 |
These figures cover the miner only. Exhaust fans, air conditioning, network equipment and power-distribution losses can raise total facility consumption.
Real-World Efficiency in Joules per Megahash
Efficiency is calculated by dividing wall power by hashrate:
4,052 W ÷ 19,120 MH/s = 0.212 J/MH
The resulting 0.212 J/MH is slightly better than the rated 0.22 J/MH because the reference unit produced more than its advertised hashrate while power remained near the expected range.
Using the pool-side average gives a more conservative result:
4,052 W ÷ 18,840 MH/s = 0.215 J/MH
For profitability planning, the pool-side efficiency of approximately 0.215 J/MH is the safer figure.
How We Tested ElphaPex DG2 Noise Under Sustained Load
The DG2 is an industrial air-cooled miner. Its acoustic profile is dominated by high-speed fans and continuous airflow through a narrow chassis. It should not be confused with the smaller and quieter DG Home series.
Sound Meter Placement and Background Noise Baseline
Noise was measured with an A-weighted sound meter placed one meter from the miner at the same height as the fan intake. Doors, windows and unrelated equipment remained in the same position throughout the measurement.
The room’s background noise was approximately 32 dBA with the miner switched off. Because decibels are logarithmic, background noise at this level had little effect on readings above 70 dBA.
The measurement position should always be stated in an ASIC review. A reading taken beside the fan outlet cannot be fairly compared with one recorded several meters away or through a closed door.
Startup, Normal Load and High-Fan Noise Measurements
| Operating condition | Noise at 1 meter |
| Background, miner off | 32 dBA |
| Startup fan ramp | 78.9 dBA |
| Normal sustained load | 75.6 dBA |
| High-fan response | 79.4 dBA |
The normal result is consistent with the commonly listed DG2 noise specification of approximately 75 dBA. This is loud enough to disrupt conversation and is inappropriate for a bedroom, office or shared living area.
Fan Tone, Vibration and Noise Outside the Test Room
The dominant sound was a steady, high-frequency fan tone rather than intermittent mechanical rattling. The chassis produced minor vibration, but it did not move across the test surface.
Placing the miner on a rigid shelf with vibration-isolating feet reduced transmitted resonance. Soft materials must not obstruct the intake, exhaust or power supply.
With a solid door closed, the noise outside the room was substantially lower but still noticeable. Duct bends, lined enclosures and distance can reduce perceived sound, although restrictive ducting may increase fan speed and internal temperature. Explore appropriate exhaust and thermal-management options in theJSBIT mining cooling collection.
What the 72-Hour Test Results Mean for Real-World Mining
The DG2’s strongest result was not its brief 20 GH/s peak but its ability to remain close to 19 GH/s for three days without a restart. That makes the unit more useful for commercial planning than a miner with higher peaks but frequent thermal throttling.
Temperature, Fan Speed and Performance Stability
Intake temperature remained near 22–25°C, with unrestricted exhaust airflow. Fan speed adjusted automatically as room conditions changed, but no sustained thermal throttling was observed.
The miner remained most stable when hot exhaust was directed away from its intake. Even an efficient ASIC converts nearly all consumed electrical power into heat, meaning a 4,052 W DG2 releases approximately 13,825 BTU/h into its environment.
Performance may differ in warmer rooms. Higher intake temperatures can cause faster fans, more noise, additional power consumption and eventual frequency reduction.
Rejected Shares, Hardware Errors and Unexpected Restarts
The pool recorded a rejected-share rate of approximately 0.38%, which is low enough for normal operation. There were no persistent hardware-error warnings and no unexpected restarts during the reference period.
| Stability indicator | 72-hour result |
| Pool rejected shares | 0.38% |
| Unexpected restarts | 0 |
| Sustained thermal throttling | Not observed |
| Pool failovers | 0 |
| Persistent hardware errors | Not observed |
Rejected shares consistently above 1% should prompt checks of network latency, pool configuration, Ethernet stability, firmware and chip temperature.
Electrical and Ventilation Requirements for Continuous Operation
The ElphaPex DG2 requires 200–240 V input and should use a properly sized dedicated circuit. At 230 V and 4,052 W, the operating current is approximately 17.6 amps before considering brief variation.
A safe deployment plan should include:
- Dedicated 200–240 V electrical supply
- Properly rated breaker, cabling, connector and PDU
- Capacity for more than 4.3 kW during startup
- Approximately 13,800 BTU/h of heat removal per miner
- Unrestricted cool-air intake
- Direct exhaust path
- Wired Ethernet
- Smoke detection and environmental monitoring
Electrical work should be inspected by a licensed professional. Never select circuit capacity solely from the average wattage measured during a short test.
Suitable Deployment Scenarios for the ElphaPex DG2
The DG2 is most suitable for:
- Mining farms with low-cost electricity
- Warehouses with dedicated exhaust systems
- Professionally prepared garages or outbuildings
- Colocation and ASIC hosting facilities
- Small commercial Scrypt operations
It is generally unsuitable for bedrooms, apartments and ordinary offices because of its 75 dBA noise level, continuous four-kilowatt load and concentrated heat output.
For operators who cannot accommodate those requirements, JSBIT’sDogecoin miner collection includes lower-power Scrypt alternatives.
Conclusion: Is the ElphaPex DG2 Stable and Efficient Enough?
Yes. The ElphaPex DG2 is stable and efficient enough for continuous Scrypt mining when installed in a properly powered and ventilated environment.
Its reference 72-hour dashboard average of 19.12 GH/s exceeded the 18 GH/s rating, while pool-side output averaged 18.84 GH/s. Wall consumption of approximately 4,052 W produced conservative pool-side efficiency of about 0.215 J/MH. No unexpected restart or sustained thermal throttling was observed.
The compromises are clear: the DG2 is loud, produces substantial heat and requires industrial-style electrical planning. It is a strong mining machine, but not a plug-and-play residential appliance.
