Evidence-controlled E9 reference: Antminer E9, model 240-E, is an Ethash miner with 6 GB of memory. Bitmain publishes six exact hashrate bins at 1,920 W. Hashrate is expressed in MH/s and must not be compared across algorithms.
| OEM bin | Hashrate | Wall power at 25°C | Normalized OEM efficiency |
|---|---|---|---|
| E9-2400M | 2,400 MH/s ±10% | 1,920 W ±10% | Withheld: OEM unit-label conflict |
| E9-2340M | 2,340 MH/s ±10% | 1,920 W ±10% | Withheld: OEM unit-label conflict |
| E9-2280M | 2,280 MH/s ±10% | 1,920 W ±10% | Withheld: OEM unit-label conflict |
| E9-2220M | 2,220 MH/s ±10% | 1,920 W ±10% | Withheld: OEM unit-label conflict |
| E9-2160M | 2,160 MH/s ±10% | 1,920 W ±10% | Withheld: OEM unit-label conflict |
| E9-2100M | 2,100 MH/s ±10% | 1,920 W ±10% | Withheld: OEM unit-label conflict |
Bitmain efficiency-unit conflict
Bitmain prints the efficiency numerics 0.80, 0.82, 0.84, 0.86, 0.89, and 0.91 with a J/TH label. That label is incompatible with the source’s MH/s hashrates and with direct power/hashrate arithmetic. For example, 1,920 W ÷ 2,400 MH/s equals 0.80 J/MH. The OEM efficiency field is therefore visibly withheld from the canonical matrix and must not be emitted in structured data. Arithmetic J/MH values may be explained as calculations, but not silently presented as corrected OEM claims.
Electrical, physical, and environmental boundaries
Exact fan record: four 12038 fans; front and rear 5,200 RPM; 12 V / 2.35 A; 360 CFM mid airflow.
| Memory | 6 GB |
|---|---|
| AC input | 200–240 V AC, 47–63 Hz |
| Maximum current | 20 A under the stated maximum condition: 40°C and 0 m altitude |
| Input wiring | Two AC input wires, 10 A per wire |
| Network | RJ45 Ethernet 10/100M |
| Miner dimensions | 520 × 195.5 × 290 mm, including PSU |
| Packaged dimensions | 680 × 316 × 430 mm |
| Net / gross weight | 17.7 kg / 19.4 kg, net including PSU |
| Operating / storage temperature | 0–40°C / -20–70°C |
| Operating humidity | 10–90% RH, non-condensing |
| Operating altitude | Up to 2,000 m |
From 900 m to 2,000 m, reduce the highest permitted operating temperature by 1°C for every 300 m increase. Wrong voltage can damage the miner. Have a qualified person verify the exact E9, PSU, both input paths, cords, connectors, circuit capacity, protection, conductors, disconnecting means, grounding, and applicable requirements. Exact PSU, cord, connector, and simultaneous-input sequence are not asserted without matching E9 evidence.
Firmware, diagnostics, and repair
- Select E9 and the exact installed revision in Bitmain’s firmware selector.
- Use the official E9 support hub for current setup, reset, firmware, troubleshooting, and repair routes.
- Start with Bitmain’s failure diagnostic guide for power, zero-hashrate, fan, temperature, firmware, control-board, or hashboard-signal symptoms.
- Use the ASIC fault finder to organize symptoms and logs.
- Request ASIC repair diagnosis with exact labels, photographs, logs, symptoms, and prior firmware actions.
- Open the Antminer E9 family hub to keep E9 and E9 Pro evidence separate.
Evidence boundaries: no normalized OEM efficiency/schema, sound level, silicon/controller/board or memory architecture, tuning, third-party firmware, residential/heat/economics, coin-currentness, lifecycle, price, release, compatibility, or cross-algorithm claim is asserted.
