VolcMiner D3 (20GH)

20 GH/s Scrypt at 3,580W continuous and 0.179 J/MH (179 J/GH) efficiency. VolcMiner's ±3 percent hashrate tolerance produces real world output between 19.4 and 20.6 GH/s. Same hashrate tier as the Bitmain L11 base at meaningfully lower power draw.

All Scrypt algorithm cryptocurrencies through merged mining. Primary coins: Litecoin (LTC), Dogecoin (DOGE), Bellscoin (BELLS). Additional Scrypt coins: Luckycoin (LKY), Junkcoin (JKC), Pepecoin (PEP) through pools that support those chains. Combined merged mining revenue typically runs 20 to 40 percent above solo LTC at the same hashrate.

Scrypt merged mining produces multiple coins simultaneously from the same hashrate. The D3 submits Scrypt proof of work once to a merged mining pool, and the pool distributes rewards across LTC, DOGE, and BELLS simultaneously to configured wallets. No additional power or hashrate consumed for the secondary coin outputs. Configure once through pool interface and collect rewards across all supported chains automatically.

0.179 J/MH (179 J/GH) at 20 GH/s and 3,580W continuous. Slightly better per megahash than the Bitmain L11 base at 0.184 J/MH. Behind the Bitmain L11 Pro at 0.172 J/MH and Bitdeer SEALMINER DL1 Air at 0.149 J/GH. Ahead of the ElphaPex DG2+ at 0.190 J/MH and Bitmain L9 at 0.21 J/MH.

Quad fan air cooling with front intake and rear exhaust airflow direction per MillionMiner specification. No external water loops or immersion. Facility requirements: ventilation for approximately 12,215 BTU per hour heat output, adequate intake and exhaust air, ambient temperature within the specified range. Internal temperature sensors manage fan RPM and hashrate throttling under thermal stress.

Depends on voltage, noise, and thermal capacity. Voltage: the wide 200 to 300V input range deploys on standard 220V appliance circuits (dryer outlets, EV chargers). Cannot practically run at 110V residential since 3,580W at 120V would require approximately 32.5 amps. Noise: 75 dB exceeds comfortable household levels and requires dedicated mining space (garage, outbuilding, insulated basement). Thermal: 3,580W requires ventilation or HVAC. For quiet home Scrypt mining at smaller scale, Fluminer L3 at 9.5 GH/s and 45 dB or Fluminer L1 Pro at 6 GH/s and 45 dB are more appropriate.

200 to 300V single phase AC input. Wider range than any competing current generation Scrypt miner (Bitmain L11 family 220 to 277V, Bitdeer SEALMINER DL1 Air 220V+). At 3,580W continuous, the unit draws approximately 16.3 amps at 220V. For international operators deploying to facilities with variable or non standard grid voltage, the D3 covers more grid configurations without external voltage regulation. Standard commercial 220 to 240V service works without modification.

L9 at 17 GH/s, 3,570W, and 0.21 J/MH. D3 at 20 GH/s, 3,580W, and 0.179 J/MH. The D3 delivers 18 percent more hashrate at nearly identical power draw (10W more) and approximately 15 percent better efficiency per megahash. For L9 operators at current conditions, the D3 delivers better per unit economics at the cost of moving away from Bitmain's ecosystem to a newer manufacturer with less established support history.

6 month VolcMiner factory warranty on new units covering manufacturing defects and hardware failures under normal operation within specified environmental ranges. Ships from MillionMiner with free DDP worldwide delivery covering all customs clearance, import duties, and taxes. Box contents: VolcMiner D3 unit, PSU, power cables, and quick start guide.

L11 base at 20 GH/s, 3,680W, and 0.184 J/MH. L11 Pro at 21 GH/s, 3,612W, and 0.172 J/MH. D3 at 20 GH/s, 3,580W, and 0.179 J/MH. The D3 matches the L11 base hashrate at 100W less power draw. The L11 Pro beats the D3 on both hashrate (+5 percent) and efficiency (-4 percent better per megahash). Voltage flexibility favors the D3 (200 to 300V versus 220 to 277V) for variable grid deployments. Ecosystem maturity favors the L11 family (broader operator familiarity, deeper third party firmware support).

SEALMINER DL1 Air at 25 GH/s, 3,725W, and 0.149 J/GH delivers 25 percent more hashrate and approximately 17 percent better efficiency per gigahash than the D3. Both are newer manufacturer alternatives to Bitmain's ecosystem. Bitdeer's backing (NASDAQ: BTDR) provides stronger manufacturer stability than VolcMiner's smaller operation. For operators choosing between non Bitmain Scrypt hardware, the DL1 Air offers better per unit economics while the D3 offers voltage flexibility and slightly lower per unit capital cost.

385 x 217 x 316 mm chassis per MillionMiner specification. Weight approximately 22 kg per MM, with alternative distributor documentation (CaptainMining, CryptoMinerBros) listing 17.5 kg likely reflecting bare chassis versus complete shipping weight with PSU and packaging.

75 dB industrial noise from quad cooling fans at peak operation. Comparable to a vacuum cleaner or busy restaurant. Disruptive through walls. Requires sound isolated deployment space: dedicated mining room, garage, outbuilding, warehouse. Not suitable for residential proximity without sound containment.

MillionMiner specifies 5 to 45 degrees Celsius at 5 to 95 percent humidity. Alternative distributor documentation varies from 0 to 40 degrees Celsius (OneMiners) to minus 20 to 45 degrees Celsius (CryptoMinerBros). The conservative range represents optimal operating conditions for sustained hashrate. For hot climate deployments, facility cooling must hold intake air below 40 degrees Celsius under peak load for stable output.

Four step setup. Verify 200 to 300V single phase circuit capable of 3,580W continuous (20 amp 220V minimum). Connect PSU to miner and to outlet. Connect Ethernet. Find miner IP via router admin or IP scanner, open VolcMiner web interface, configure Scrypt merged mining pool URL and LTC/DOGE/BELLS wallet addresses, change default credentials. Verify hashrate reaches 19+ GH/s within 10 minutes.

Major Scrypt merged mining pools accept D3 hashrate including F2Pool, Poolin, ViaBTC, Prohashing, Litecoinpool. Pool fees typically 0.5 to 2 percent. Verify Bellscoin support before deployment since not all Scrypt pools have added BELLS.

Third party firmware support for VolcMiner hardware is limited compared to the Bitmain ecosystem. Most D3 operators run stock VolcMiner firmware. BraiinsOS style tuning has not targeted VolcMiner specifically. Operators relying on firmware tuning should plan for stock firmware operation and monitor VolcMiner firmware updates.

Yes. MillionMiner hosting services accept D3 units at managed facilities with appropriate single phase power distribution. The wide 200 to 300V voltage range simplifies facility compatibility assessment. Contact MillionMiner for hosting rate tiers and availability.

Mixed assessment depending on operator profile. Pro factors: wider 200 to 300V voltage range than any competing Scrypt miner, 100W power draw advantage versus Bitmain L11 base, competitive efficiency mid tier, 6 month manufacturer warranty, merged mining revenue advantage. Con factors: VolcMiner is a newer manufacturer with less established support history than Bitmain, less third party firmware support, L11 Pro and Bitdeer DL1 Air deliver better efficiency, smaller installed base affects long term secondary market resale. For international operators with variable grid voltage facilities or operators prioritizing VolcMiner's specific spec advantages, the D3 delivers competitive economics. For operators committed to Bitmain's ecosystem or prioritizing ecosystem maturity, the L11 Pro remains the default air cooled choice.

For Scrypt family alternatives: Bitmain L11 Pro (21 GH/s, 172 J/GH) for better efficiency within Bitmain's ecosystem, L11 base (20 GH/s, 184 J/GH) at direct hashrate parity with the D3, L9 (17 GH/s) at lower capital cost, hydro L11 HU6 (33 GH/s) or L11 Hyd 2U (35 GH/s) for rack mount hydro deployment. Bitdeer SEALMINER DL1 Air (25 GH/s, 149 J/GH) provides alternative non Bitmain vendor with better efficiency. For algorithm diversification: Antminer S21 XP (270 TH/s), S23 (318 TH/s), or S23E Hyd 2U (865 TH/s) cover SHA-256 Bitcoin. Antminer KS7 (45 TH/s) covers Kaspa KHeavyHash. For quiet Scrypt on separate infrastructure: Fluminer L3 (9.5 GH/s, 45 dB) or Fluminer L1 Pro (6 GH/s, 45 dB). MillionMiner's ASIC hosting service covers turnkey D3 deployment at industrial electricity rates without facility CapEx.
