BM1485 Brand New ASIC Chip for Antminer L3 L3+ L3++ Hashboard

BM1485 ASIC Chip – Antminer L3 / L3+ / L3++ Hashboard Repair Part

The BM1485 is the scrypt (Litecoin / Dogecoin) ASIC chip used across Bitmain's Antminer L3, L3+, L3++ hashboards. A dead or cracked BM1485 is the single most common cause of a missing hash engine, a low chip-count scan, or a chain stuck at a lower-than-expected hashrate. This brand-new, original SMD replacement restores full chip count on the repaired chain and returns the miner to its rated hashrate without any firmware change.

Diagnosing a Failed BM1485

Classic symptoms: chain scan reports missing chips (for example 71 / 72 or 70 / 72 on an L3+), dead chip localised on thermal imaging as a cold spot along the string, or a hard short measured across the BM1485 I/O. Before reflowing, confirm the neighbouring chips and the local Vcore rail are healthy — a collapsed rail can mimic a dead chip. When the failure is isolated to the chip itself, desolder with hot air at the BM1485's specified profile, clean the pads, re-tin with a matching stencil, and re-place with the BM1485 oriented correctly against the pad-1 marker.

Why BM1485 Replacements Matter for L3 Series Uptime

L3 / L3+ / L3++ miners remain highly profitable at merge-mined Litecoin + Dogecoin rates, and a single dead chip can block an entire chain of ~72 hash engines. Keeping a small BM1485 buffer on hand lets a farm operator repair a chain in under an hour and avoid writing off an otherwise functional hashboard.
