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.

X11 es una función hash criptográfica que sirve como la columna vertebral de Dash mecanismo de consenso proof-of-work. Este algoritmo procesa datos de entrada de cualquier longitud y produce un valor hash fijo, garantizando seguridad e integridad en el proceso de minería.
