Bitmain Antminer E3 Ethash/Etchash historical OEM reference
Two authentic OEM E3 rating profiles: 180 MH/s ±5% at launch and the later 191 MH/s support specification with 4.4 J/MH ±10%; EOS since June 9, 2020.
Quick answer
The Bitmain Antminer E3 Ethash/Etchash historical OEM reference is a Etchash miner rated about 191 MH/s at roughly 800 W.

Evidence-controlled Antminer E3 reference: Bitmain published two time-scoped rating profiles for the same E3 model. The manufacturer calls the algorithm Ethash; this site’s directory taxonomy uses Etchash for historical discovery. Neither term establishes current network compatibility.
| OEM source profile | Hashrate | Frequency | Power consumption | Efficiency |
|---|---|---|---|---|
| Launch profile, July 2018 | 180 MH/s ±5% | Not stated | 800 W; tolerance not stated | Not published |
| Support specification, March 2019 | 191 MH/s; tolerance not stated | 1600M | 800 W ±10% | 4.4 J/MH ±10% OEM |
These are evidence-dated source profiles, not separate hardware SKUs and not user-selectable operating modes. No OEM 190 MH/s profile was found. This canonical uses the later 191 MH/s support specification for its headline value while preserving the authentic 180 MH/s launch profile.
Electrical boundary
The E3 requires 11.6–13.0 V DC through seven PCIe power connectors. Bitmain’s current compatibility roster supports APW3-series, APW5, and APW7 power supplies. This is the miner’s DC input boundary, not a facility-mains specification. A qualified person must verify the selected PSU’s exact revision and nameplate, facility supply, circuit protection, conductors, connectors, grounding, and disconnect before energizing it.

Firmware, diagnostics, and end of service
- Select E3 and the exact revision in Bitmain’s firmware selector. Do not cross-flash another model or control-board image.
- Open Bitmain’s E3 support page.
- Use Bitmain’s general ANTMINER diagnostic workflow.
- Review Bitmain’s EOS list: E3 reached end of service on June 9, 2020.
- Organize symptoms and logs; request repair triage; open the E3 service router.
Bitmain’s algorithm roster, last updated September 2, 2024, associates E3 with ETC and CLO. That is evidence-dated manufacturer documentation, not verification of live-network compatibility in 2026. No facility-mains, memory or DAG-capacity, architecture, economics, residential-use, heat-use, tuning, current compatibility, or parts-interchangeability claim is asserted.
