Bitmain Antminer D7 (1286Gh) Antminer D7 1.286Th

The Bitmain Antminer D7 (1.286 Th/s) is a purpose-built X11 miner delivering 3,148 W at the wall for an energy efficiency of about 2.45 J/Gh, making it well suited for Dash and other X11 coins where sustained throughput and predictable power draw matter; it pairs adaptive frequency tuning with a four-fan push–pull cooling layout to stabilize hashrate under varying thermal and power conditions, operates at roughly 75 dB, and is rated for ambient temperatures of 5–45°C and humidity from 5% to 95% non-condensing, which calls for clean airflow and dust control to maintain long-term performance. For electrical planning, the unit is best run on a dedicated 200–240 V circuit, drawing approximately 13–16 A depending on voltage and overhead, and it exhausts around 10.7 kBTU/h of heat, so rack spacing, intake filtration, and hot–cold aisle separation materially improve uptime and fan longevity. Management is via Ethernet with a browser-based interface supporting pool failover and standard Stratum, watchdog auto-recovery, and per-board monitoring, and setup is straightforward with DHCP or static IP addressing; consistent firmware updates and periodic fan and heatsink maintenance reduce rejects and throttling. Profitability should be evaluated with a miner calculator that accounts for network difficulty, block reward dynamics, pool fees, stale and reject rates, uptime assumptions, and local electricity rates; scenario testing for difficulty and price shifts, plus a sensitivity check on power cost and cooling overhead, yields a more reliable view of breakeven and operating margin.

The Bitmain Antminer D7 (1286 Gh/s, also referred to as 1.286 Th/s) is a purpose-built X11 unit that couples an ASIC hashboard stack with controller-level adaptive frequency tuning and per-chain voltage adjustments to align performance with real-time power conditions, cutting inefficiencies and stabilizing output under temperature swings; its four high-speed PWM fans drive airflow through a dense fin-array heat sink design to keep components within target envelopes, with an operating range of 5–45°C and 5–95% relative humidity (non‑condensing) and a typical acoustic profile near 75 dB, which makes clean intake filtration and unobstructed exhaust mandatory in high-density racks; at the wall it targets about 3,148 W for roughly 1.286 Th/s, translating to near 2.45 J/Gh, while the integrated power stage uses active PFC and fast transient response to damp rapid load changes that otherwise appear as share drops or throttling over long duty cycles; management is via Ethernet with a browser interface supporting DHCP or static IP, pool failover and Stratum, per‑board temperature and fan telemetry, watchdog auto‑recovery, and a cgminer‑compatible API for fleet tools, and security hygiene-signed firmware, timely updates, changed defaults, and VLAN isolation-reduces operational risk; deployment should assume a dedicated 200–240 V circuit with C19‑rated PDU and cabling, verified grounding, no daisy‑chained adapters, and ventilation sized to remove a continuous thermal load equivalent to the electrical draw to prevent recirculation and forced clock reductions; routine care-monthly dust removal, periodic fan bearing and RPM checks, log review for rising ASIC or VRM temperatures, and thermal interface refresh when hotspots trend upward-helps maintain steady clocks and low reject rates; engineered for Dash and other X11 assets, the D7’s combination of high throughput, firmware‑exposed tuning, robust cooling, and stable power delivery makes it a precise tool for operators who keep power quality, airflow discipline, and firmware integrity under documented control.
