Key Features

1. Precision Engineering for S21 Optimization

• Exact Compatibility: Direct replacement for Antminer S21’s original design, ensuring seamless integration with SHA-256 algorithm optimization.
• BM1368 ASIC Chips: Bitmain-certified chips deliver stable 17.5 J/TH efficiency and sustained 200TH/s hashrate, backed by advanced thermal management.
• Rigorous Testing: Each hashboard undergoes 48-hour stress tests (hashrate stability, temperature, voltage) with video documentation for transparency.

2. Risk-Free Purchase Assurance

• 30% Deposit Reservation: Secure your order via crypto.
• Transparent Verification: Receive a customized test video showing real-time metrics (serial number, hashrate, chip health) before final payment.
• Secure Packaging: Anti-static foam, shockproof padding, and tamper-evident seals ensure damage-free transit.

3. Profit-Driven Mining Repairs

• Critical Component Replacement: A single faulty hashboard can cripple your miner’s output—replace promptly to avoid shutdowns and revenue loss.
• Cost Efficiency: Avoid full-miner replacement costs; repair only what’s broken.

Why Replace Faulty Hashboards?

A failing hashboard directly impacts profitability:

• ⬇️ Hashrate Collapse: Instability or shutdowns reduce total mining output.
• ⬇️ Revenue Loss: Lower efficiency = fewer BTC mined = profit erosion.
• ⬆️ Repair Costs: Delayed action risks cascading hardware failures.

Step-by-Step Replacement Guide

1. Prepare Tools: New S21 hashboard, screwdriver, anti-static gear.
2. Power Down: Disconnect miner and wait 10 minutes for components to cool.
3. Remove Casing: Unscrew outer shell and detach fans/cables.
4. Extract Faulty Board: Carefully disconnect and remove the defective hashboard.
5. Install New Board: Align and secure the replacement, ensuring polarity matches.
6. Reassemble: Reconnect components, seal casing, and power up.
7. Verify Performance: Monitor hashrate stability via mining pool dashboard.
