Antminer B3 and B7 Tensority evidence router
Antminer B3/B7 evidence router: these Tensority/BTM records are not interchangeable. B3 has an exact baseline specification and official optional firmware procedure. B7 has identity, fan, and PCB-temperature evidence only.
| Canonical | Evidence state | Safe facts |
|---|---|---|
| B3 | Exact baseline | 780 H/s; 360 W +7%; 0.46 J/H +7%; external 11.6–13 V DC, seven PCIe |
| B7 | Evidence-limited | Tensority/BTM identity; one 12038 fan; PCB maximum 75°C |
Bitmain’s update_1000.tar.gz is an official B3 hashrate-improvement procedure, not an exact post-upgrade performance matrix. The former separate B3 1K record should consolidate into the B3 canonical. Do not inherit B3’s APW3/APW5/APW7, voltage, connectors, firmware, dimensions, or performance onto B7.
No compatibility, economics, home, heat-use, or unsupported ProductModel claim is implied.
