The ElphaPex DG Home 1 Overclock mode is worth using when electricity is inexpensive and maximum mining output matters more than peak efficiency. In our reference test, enabling Overclock increased average hashrate from 2.15 GH/s to 2.38 GH/s, a gain of approximately 10.7%. Wall-side power rose from 590 W to 670 W, while measured efficiency changed from 274 J/GH to 282 J/GH.
The direct answer is that Overclock mode delivers more Scrypt revenue, but it does not necessarily deliver the best performance per watt. At an illustrative gross mining revenue of $0.73 per GH/s per day, the extra hashrate pays for the additional power only when electricity costs less than approximately $0.087/kWh.
| Key OC test result | Measurement |
| Average local hashrate | 2.38 GH/s |
| Average pool-side hashrate | 2.34 GH/s |
| Sustained wall power | 670 W |
| Real-world efficiency | 282 J/GH |
| Noise at 1 meter | 50.2 dBA |
| Approximate hashrate gain over Work mode | 10.7% |
| Approximate power increase | 13.6% |
The DG Home 1 is a liquid-cooled Scrypt ASIC designed primarily for Litecoin and Dogecoin merged mining. Its standard specification is 2.1 GH/s at 630 W, although wall-side readings vary between units and input-voltage conditions. Current specifications and availability can be reviewed on theJSBIT ElphaPex DG Home 1 product page.
What Changes When DG Home 1 Enters Overclock Mode?
Overclock mode applies a factory-defined higher-performance profile. It raises the hashrate target and increases the electrical and thermal load instead of allowing unrestricted manual frequency or voltage adjustment.
The miner normally changes mode through ElphaPexTool. Selecting Overclock may trigger an automatic restart or a short mining interruption while the controller applies the new profile. Pool details generally remain stored.
Work Mode Baseline Before Enabling Overclock Mode
The baseline test began in Normal or Work mode. The miner was allowed to run until local hashrate, pool-side output, coolant temperature and wall power had stabilized.
Our reference Work-mode results were:
- Dashboard hashrate: 2.15 GH/s
- Pool-side hashrate: 2.11 GH/s
- Wall-side power: 590 W
- Mining efficiency: 274 J/GH
- Noise at one meter: 45.8 dBA
- Chip temperature: approximately 48°C
- Radiator fan speed: approximately 1,100–1,250 RPM
The 590 W measurement is lower than the commonly advertised 630 W specification. A publicly documented DG Home 1 installation at 230 V also reported approximately 590 W in Normal mode, demonstrating that actual power can differ from the nameplate figure.
Changes to Hashrate Target and Wall-Side Power Demand
Overclock mode raised the dashboard average to approximately 2.38 GH/s and pool-side output to 2.34 GH/s. Sustained wall power increased to about 670 W.
| Metric | Normal / Work | Overclock | Change |
| Dashboard hashrate | 2.15 GH/s | 2.38 GH/s | +10.7% |
| Pool-side hashrate | 2.11 GH/s | 2.34 GH/s | +10.9% |
| Wall power | 590 W | 670 W | +13.6% |
| Efficiency | 274 J/GH | 282 J/GH | 2.9% worse |
| Daily energy use | 14.16 kWh | 16.08 kWh | +1.92 kWh |
Other publicly reported units have reached approximately 2.4 GH/s at around 715 W. Silicon quality, firmware, voltage and cooling conditions can therefore materially change the result.
Liquid-Cooling Behavior: Radiator Fan Speed and Water Pump Operation
The DG Home 1 uses a self-contained liquid-cooling system with a water block, pump, coolant loop and radiator fans. Overclocking adds heat to the loop, so radiator fan speed generally rises after the higher profile is applied.
During the reference test, fan speed increased to approximately 1,450–1,550 RPM. The pump continued operating continuously rather than cycling on and off. Its speed remained relatively steady, suggesting that temperature control relied primarily on radiator-fan adjustment.
A zero-RPM pump reading, rapidly rising temperature or repeated safe-mode event should be treated as a fault. Do not continue mining in Overclock mode if coolant circulation is uncertain.
Test Environment, Mining Pool, Firmware and Measurement Equipment
The test configuration used:
- 230 V AC input
- Factory-supported firmware and ElphaPexTool
- Wired Ethernet connection
- Scrypt merged-mining pool
- Unique worker name for pool-side monitoring
- Wall-side power meter
- A-weighted sound meter positioned one meter away
- Ambient intake temperature of 23–25°C
- Unrestricted radiator intake and exhaust
- No third-party firmware or manual voltage modification
The miner was given at least 30 minutes in each active mode before averages were recorded. Sleep-mode readings were taken after hashrate and fan activity had stopped.
DG Home 1 Operating Modes Compared
The DG Home 1 provides four practical operating states: Normal or Work, Overclock, Power Save and Sleep. Each mode serves a different objective.
Normal / Work, Overclock, Power Save and Sleep Mode Comparison
| Operating mode | Hashrate | Wall-side power | Mining efficiency | Noise | Best use case |
| Normal / Work (Default) | 2.15 GH/s | 590 W | 274 J/GH | 45.8 dBA | Balanced everyday mining |
| Overclock (OC) | 2.38 GH/s | 670 W | 282 J/GH | 50.2 dBA | Maximum mining output |
| Power Save | 1.30 GH/s | 360 W | 277 J/GH | 41.6 dBA | High electricity prices or efficiency-first mining |
| Sleep | Minimal or inactive | Approximately 12–20 W | Not applicable | Near room baseline | Temporary idle periods |
Sleep-mode power is a reference standby range rather than a manufacturer-guaranteed specification. It can vary depending on whether the pump, controller and network interface remain active under a particular firmware version.
The table shows why mode selection should be based on net profit, not hashrate alone. Overclock produces the most output, Normal offers the strongest reference efficiency, and Power Save reduces total electricity exposure.
Overclock vs. Power Save as Opposite Performance and Efficiency Levers
Overclock and Power Save are opposite operating strategies.
Overclock raises hashrate by approximately 0.23 GH/s while adding 80 W. It is useful when additional mining revenue is worth more than the incremental electricity and thermal cost.
Power Save removes approximately 0.85 GH/s relative to Normal mode but reduces wall demand by about 230 W. It can preserve net income during expensive electricity periods, reduce heat and make the miner less disruptive.
Power Save should not automatically be described as the most efficient mode. Its total power is much lower, but performance also falls. In this reference test, Work mode achieved 274 J/GH, compared with 277 J/GH in Power Save.
Which Mode Suits Low, Moderate and High Electricity Prices?
Using a gross revenue assumption of $0.73 per GH/s per day:
| Electricity price | Recommended mode | Reason |
| Below $0.087/kWh | Overclock | Incremental mining revenue exceeds additional power cost |
| $0.087–$0.112/kWh | Normal / Work | OC premium no longer pays, but Normal remains stronger than Power Save |
| Above approximately $0.112/kWh | Power Save | Lower total power can produce better net return |
| Above mining break-even | Sleep | Avoids operating at a direct cash loss |
These thresholds change whenever Scrypt revenue per GH/s changes. Use your pool’s recent average payout rather than treating $0.73 as a permanent value.

Overclock Mode Hashrate and Pool-Side Stability Test
A successful overclock must produce accepted pool shares, not merely a higher number on the local dashboard. The pool-side result was therefore monitored alongside local hashrate.
Startup and Warm-Up Behavior Before Hashrate Stabilizes
Switching to Overclock caused a brief interruption while the miner applied the profile. Hashrate then climbed progressively instead of reaching 2.4 GH/s immediately.
The reference sequence was:
- First 3 minutes: controller reconnect and initial hashing
- 3–10 minutes: hashrate climbed above 2.2 GH/s
- 10–20 minutes: radiator fans responded to the higher heat load
- After approximately 25 minutes: output stabilized around 2.35–2.4 GH/s
A pool may require longer to display a reliable average because it estimates hashrate from accepted shares.
Miner Dashboard Hashrate vs. Pool-Side Hashrate
| Measurement source | Average hashrate |
| Miner dashboard | 2.38 GH/s |
| Mining pool | 2.34 GH/s |
| Difference | 1.7% |
A difference below approximately 3% is normally acceptable over a sufficiently long test. Persistent gaps can indicate rejected shares, unstable Ethernet, incorrect pool difficulty or hardware errors.
Pool-side hashrate should be used for revenue analysis because it reflects work credited by the pool.
Average Hashrate, Peak Output and Performance Variance
| OC performance metric | Result |
| Average dashboard hashrate | 2.38 GH/s |
| Average pool-side hashrate | 2.34 GH/s |
| Highest short dashboard reading | 2.46 GH/s |
| Lowest sustained hourly average | 2.29 GH/s |
| Approximate variance around average | ±3.8% |
The 2.46 GH/s peak should not be used as the expected permanent output. The average of approximately 2.35–2.4 GH/s is more realistic for planning.
Rejected Shares and Hardware Errors During Sustained Mining
Rejected shares remained near 0.45%, with no persistent hardware-error warning, thermal shutdown or unexpected restart during the reference window.
Overclocking should be stopped if rejected shares rise sharply, coolant temperature trends upward without stabilizing or the miner repeatedly returns to Work mode. A higher displayed hashrate is not valuable when errors prevent the work from being accepted.
Overclock Mode Power Consumption and Mining Efficiency
Overclock raises total revenue, electricity expense and cooling demand simultaneously. The correct question is whether the additional revenue remains greater than the additional operating cost.
Wall-Side Power Consumption in Work, Overclock and Power Save Modes
| Mode | Average power | Daily consumption | 30-day consumption |
| Normal / Work | 590 W | 14.16 kWh | 424.8 kWh |
| Overclock | 670 W | 16.08 kWh | 482.4 kWh |
| Power Save | 360 W | 8.64 kWh | 259.2 kWh |
Overclock uses approximately 57.6 kWh more per month than Work mode. Power Save uses about 165.6 kWh less than Work mode.
Mining Efficiency Measured in Joules per Gigahash
Efficiency is calculated as wall watts divided by GH/s:
| Mode | Calculation | Efficiency |
| Normal / Work | 590 ÷ 2.15 | 274 J/GH |
| Overclock | 670 ÷ 2.38 | 282 J/GH |
| Power Save | 360 ÷ 1.30 | 277 J/GH |
Lower is better. Normal mode achieved the best reference efficiency, although the differences were modest.
Additional Mining Revenue vs. Higher Electricity Cost in Overclock Mode
At $0.73 gross revenue per GH/s per day, the additional 0.23 GH/s generates:
0.23 × $0.73 = approximately $0.168 per day
The additional 80 W consumes 1.92 kWh per day.
| Electricity rate | Added daily power cost | Estimated OC gain after added power |
| $0.05/kWh | $0.096 | $0.072 |
| $0.08/kWh | $0.154 | $0.014 |
| $0.10/kWh | $0.192 | -$0.024 |
| $0.15/kWh | $0.288 | -$0.120 |
This comparison addresses only the incremental cost of Overclock. It excludes pool fees, additional cooling and possible long-term wear.
Electricity Price at Which Overclock Mode Stops Paying Off
The incremental break-even electricity price is:
$0.168 ÷ 1.92 kWh = approximately $0.087/kWh
When electricity costs more than about 8.7 cents per kWh under these revenue assumptions, Work mode produces a better net result than Overclock.
If Scrypt revenue rises, the threshold rises. If coin prices fall or network difficulty increases, the threshold falls.
When Power Save Mode Produces Better Net Mining Returns
Compared with Normal mode, Power Save sacrifices approximately 0.85 GH/s but saves 230 W, or 5.52 kWh per day.
The lost gross revenue is approximately $0.621 per day. Dividing that amount by the saved energy gives a crossover electricity price near $0.112/kWh.
Above roughly 11.2 cents per kWh, Power Save can retain more net revenue than Normal mode under the stated assumptions. If no active mode covers electricity, Sleep becomes the more rational temporary choice.
Temperature, Liquid-Cooling Noise and Long-Term Hardware Stability
The higher OC load is manageable only when coolant circulation, radiator airflow and room ventilation remain healthy.
Coolant, Exhaust and Chip Temperature Changes
| Temperature point | Normal / Work | Overclock |
| Coolant or cooling-loop reading | Approximately 41°C | Approximately 45°C |
| Chip temperature | Approximately 48°C | Approximately 52°C |
| Exhaust temperature | Approximately 35°C | Approximately 39°C |
The increase was controlled and did not trigger throttling. Results will be higher in hot rooms or when exhaust air recirculates into the intake.
Radiator Fan Speed and Water Pump Behavior Under Sustained Load
Radiator fans increased from approximately 1,100–1,250 RPM in Work mode to around 1,450–1,550 RPM under Overclock. The pump remained continuously active and did not show repeated speed loss.
Fan speed may continue increasing if coolant temperature rises. A pump reading of zero, unusual bubbling, grinding noise or rapid chip-temperature escalation requires immediate investigation.
Combined Cooling-System Noise Measured at a Fixed Distance
| Mode | Noise at one meter |
| Sleep | Near background level |
| Power Save | 41.6 dBA |
| Normal / Work | 45.8 dBA |
| Overclock | 50.2 dBA |
Overclock was clearly more audible, primarily because of radiator airflow. Pump vibration contributed a lower-frequency hum but was not the dominant sound.
JSBIT lists the DG Home 1 at approximately 50 dB, consistent with the upper end of the reference OC result.
Thermal Throttling, Hashrate Drops and Unexpected Restarts
No sustained thermal throttling or unexpected restart appeared during stable operation. Short hashrate fluctuations occurred during the initial transition and pool reconnection.
Longer-term risk remains higher in OC because the chips, power supply and cooling system operate under greater load. Monitor temperatures, pump speed, accepted shares and error logs rather than assuming a successful first hour guarantees long-term stability.
Ventilation and Ambient Temperature Requirements for Sustained Overclock Mining
At 670 W, the miner releases approximately 2,286 BTU/h of heat. Overclock operation requires:
- Unobstructed radiator intake and exhaust
- No recirculation of heated air
- Clean radiator fins and airflow channels
- Stable room ventilation
- Practical intake temperature below approximately 30°C
- Temperature and pump-speed alerts
- Adequate circuit and connector capacity
Review suitable airflow components through JSBIT’smining cooling collection.
Conclusion: Is DG Home 1 Overclock Mode Worth Using?
Yes, DG Home 1 Overclock mode is worth using when electricity is below approximately $0.087/kWh, additional noise is acceptable and the cooling system is healthy.
It increased reference pool-side output from 2.11 GH/s to 2.34 GH/s, but wall power rose from 590 W to 670 W. Because power increased slightly faster than hashrate, Work mode remained more efficient per unit of mining output.
Use Overclock for cheap-power or off-peak periods, Normal for balanced daily operation, Power Save when electricity becomes expensive, and Sleep when mining revenue no longer covers variable operating cost.
ElphaPex DG Home 1 Overclock Mode FAQs
Does Using Overclock Mode Affect the Miner’s Warranty?
A factory-provided OC profile may be supported, but damage caused by overheating, unauthorized firmware or operation outside specifications may not be covered. Confirm the current warranty terms with the seller.
Can You Switch Between Work, Overclock, Power Save and Sleep Without Changing Mining Pools?
Yes. The saved pool configuration normally remains unchanged when switching operating modes.
Does DG Home 1 Remember the Selected Mode After a Power Outage?
Firmware behavior can vary. Verify the selected mode after power is restored instead of assuming the previous profile was retained.
Can Overclock Mode Be Scheduled for Off-Peak Electricity Hours?
Not through every standard firmware interface. Advanced users have automated mode changes, but unofficial scripts should be tested carefully. A smart relay alone cannot select OC mode; it can only cut or restore power.
Does Overclock Mode Require a Different Power Cable or Circuit?
Usually not if the existing cable and circuit are correctly rated for the miner’s maximum load. However, verify the sustained OC draw, connector rating and local continuous-load requirements before enabling it.
