BM1387BE Brand New ASIC Chip for Antminer S9j Hashboard Repair
The BM1387BE is the core hashing ASIC chip used in Bitmain's Antminer S9j and T9j series hashboards. When a hashboard loses hash rate or fails chip scanning, one or more defective BM1387BE chips are typically the root cause. This brand new, original replacement chip allows repair technicians to restore full hash rate performance without replacing the entire hashboard — saving significant cost on one of the most widely deployed mining platforms in the world.

How to Diagnose Faulty BM1387BE Chips on S9j Hashboards
Identifying a defective BM1387BE chip requires a systematic approach. Start by running the miner's built-in chip scan or using a dedicated test fixture to isolate which chip position has failed. Common indicators include missing ASIC chips in the kernel log, reduced hash rate on a specific hashboard, or elevated chip temperatures. Once the faulty chip is located, it can be desoldered with a hot air station and replaced with a new BM1387BE using standard BGA/SMD rework techniques.
BM1387BE Chip Replacement for S9j Hash Rate Restoration
The Antminer S9j remains one of the most cost-effective SHA-256 miners for operations with low electricity costs. Replacing individual BM1387BE chips is far more economical than purchasing new hashboards. Each S9j hashboard contains 63 BM1387BE chips — even a single defective chip can cause the entire board to underperform or shut down. We supply these chips in any quantity, from single units for one-off repairs to bulk orders for professional repair centers.
