Evidence-controlled Antminer X3 reference: Bitmain publishes one performance lane in native kH/s and J/kH units.
| Hashrate | Power consumption | Efficiency | Frequency |
|---|---|---|---|
| 220 kH/s | 500 W +7% | 2.27 J/kH +7% | 400 MHz |
Algorithm-label boundary: Bitmain’s maintained map associates X3 with XMC but prints “Menero Classic” and “Croptonight.” CryptoNight is used here only as a normalized spelling of the manufacturer’s label. The exact algorithm variant and current network or pool compatibility remain unresolved. Bitmain’s historical X3 pool article supports XMC identity only; its old pool endpoints are not presented as current operating advice.
Hardware, cooling, and environment
| Hashboards / chips | 3 / 180 total |
|---|---|
| Miner-side PCIe connectors | 10 |
| Fan | One 12038 fan; 4,300 RPM; 12 V / 2.4 A; 209.8 CFM |
| Operating temperature | 15–35°C |
| Humidity | <70% |
| Published temperature ceilings | 80°C PCB; 127°C chip |
| Sound | 76 dB |
| Miner dimensions / net weight | 334 × 125 × 207 mm / 5.50 kg |

Bitmain classifies X3 as fixed-frequency. The published 400 MHz value is an identity/specification fact, not operating-modification guidance.
External-PSU electrical boundary
The X3 accepts 11.6–13 VDC through 10 miner-side PCIe connectors. Bitmain’s roster lists APW3, APW5, and APW7 families for X3. These facts describe the miner-side DC boundary and manufacturer roster; they do not establish an individual PSU revision’s input rating.
Facility AC voltage, current, frequency, cord, connector, protection, and grounding remain unresolved. A qualified person must inspect the exact PSU nameplate and revision and verify the complete installation before energizing it. No PSU, board, fan, or other cross-model interchangeability is implied.
Firmware, recovery, diagnostics, and end of service
- Open Bitmain’s X3 support page.
- Select X3 and the exact revision in Bitmain’s firmware selector; do not cross-flash another model.
- Follow Bitmain’s miner security workflow.
- Use the recovery procedure Bitmain assigns to X3; verify the exact model and control board before writing media.
- Use Bitmain’s X3-inclusive socket-connection workflow.
- Use Bitmain’s general diagnostic workflow.
- Organize symptoms and logs; request repair triage; open the X3 service router.
End of service: Bitmain’s current consolidated roster dates the X3 group to May 9, 2020, while an older notification prints May 10, 2020. The durable conclusion is that X3 reached end of service in May 2020; this page does not imply continuing manufacturer repair coverage.
No architecture, economics, residential-use, heat-use, operating modification, compatibility, or parts-interchangeability claim is asserted. Primary source: Bitmain X3 Specifications. Reviewed August 28, 2026.
