Antminer S7 evidence-limited reference

Evidence-limited Antminer S7 record: Bitmain’s support corpus confirms the Antminer S7 identity and provides S7-specific operating and troubleshooting routes. A durable Bitmain-hosted product specification was not found in the current specification library, so this page does not publish numerical performance, electrical, physical, acoustic, cooling, or thermal claims.

Evidence boundary

Commonly repeated S7 figures are intentionally withheld from this canonical until an exact manufacturer-controlled specification can be recovered. No numerical ProductModel, efficiency, circuit, connector, board, chip, fan, temperature, weight, or dimension assertion should be generated from this record.

Firmware and service

• Use Bitmain’s firmware selector and match the exact S7 hardware and control-board revision before download. Do not cross-flash another model.
• Follow Bitmain’s firmware download workflow.
• Use Bitmain’s general diagnostic workflow, which specifically routes fixed-frequency S7 troubleshooting.
• Review Bitmain’s S7-named pool configuration workflow.
• Organize symptoms and logs; request repair triage; open the S7 evidence router.

End of service: Bitmain’s current roster and an older notification differ by one day, but both place S7 end of service in May 2020.

No performance, installation, architecture, economics, residential-use, heat-use, tuning, compatibility, or parts-interchangeability claim is asserted. Reviewed August 28, 2026.
