| Status | OEM support reference |
Evidence-controlled DR7 reference: the exact Bitmain specification prints the algorithm/coin lane as Blake256(r14) / SCP. That wording is retained as a source claim; it is not replaced with DR3/DR5’s Blake_256/DCR/HC map.
| Hashrate | Wall power at 25°C | Printed OEM efficiency | Transparent arithmetic |
|---|---|---|---|
| 127 TH/s | 2,730 W | 21.5 J/Ksol | 2,730 ÷ 127 ≈ 21.496 J/TH |
Official-source unit conflict: J/Ksol is dimensionally incompatible with the source’s TH/s hashrate and direct arithmetic. Both are shown, but no normalized OEM efficiency is selected. Efficiency must be withheld from metadata and structured data.
Electrical and physical boundary
DR7 requires 220–240 V AC, 47–53 Hz, and 20 A through two AC input wires rated 10 A each. Wrong voltage can damage the server. A qualified person must verify both inputs, exact labels, cords/connectors, circuit capacity, protection, conductors, disconnecting means, grounding, and ventilation. No simultaneous-switching sequence is asserted.
