BM1366AL ASIC Chip — The Heart of the S19 XP
The Bm1366 chip is a genuine replacement ASIC chip for mining hardware.
The BM1366AL is Bitmain’s 5nm SHA-256 ASIC chip — the specific variant that powers the Antminer S19 XP, one of the most efficient Bitcoin miners of its generation. Whether you’re bringing a dead hashboard back to life or building a Bitaxe Ultra open-source solo miner from scratch, this is the silicon that does the work. Sourced from brand-new equipment by D-Central’s technicians — the same team that has repaired thousands of ASIC miners across 38+ model-specific repair pages.
The BM1366 family represents Bitmain’s leap to 5nm process technology, delivering a massive improvement in joules-per-terahash efficiency over previous generations. The AL variant is the exact chip used on S19 XP hashboards — drop it in, reflow, and you’re back to hashing.

Dual Use: Repair and Build
ASIC Repair — Antminer S19 XP
A single failed chip can take an entire hashboard offline. If your S19 XP is underperforming, throwing ASIC errors, or running with missing hashrate, a bad BM1366AL is the most common culprit. D-Central sources these chips from brand-new equipment — not salvaged from burned-out boards — so you’re getting silicon that hasn’t been thermally stressed through months of operation. Swap the failed chip, reflow the solder, and your hashboard comes back to full capacity.
Not comfortable doing it yourself? D-Central’s ASIC Repair service has repaired thousands of miners across every major manufacturer. We have dedicated repair pages for 38+ ASIC models, including the S19 XP. Send us your board — we’ll diagnose it, replace what’s needed, and get it hashing again.
Bitaxe Ultra Builds — Open-Source Solo Mining
The Bitaxe Ultra runs on the BM1366 chip family. If you’re sourcing components for a DIY Bitaxe Ultra build, the BM1366AL is a direct-fit chip. One chip, one board, solo mining on the Bitcoin network — no pool, no middleman. The BM1366’s 5nm efficiency means your Bitaxe Ultra sips power while throwing hashes at the blockchain. It’s a lottery ticket that runs 24/7, and every hash counts.
D-Central is a pioneer in the Bitaxe ecosystem — we created the original Bitaxe Mesh Stand, developed leading heatsink solutions, and stock every Bitaxe variant and accessory. When you buy BM1366 chips from us, you’re buying from a team that knows this silicon inside and out.
BM1366AL vs. BM1366BS — Know Your Variant
| Variant | Primary ASIC | Bitaxe Compatible |
|---|---|---|
| BM1366AL | Antminer S19 XP | Bitaxe Ultra |
| BM1366BS | Antminer S19k Pro | Bitaxe Ultra |
Both variants belong to the BM1366 family and both work in Bitaxe Ultra builds. The difference is the target ASIC miner: the AL variant is designed for S19 XP hashboards, while the BS variant fits S19k Pro boards. For repair work, make sure you’re ordering the correct variant for your machine. For Bitaxe builds, either variant works.
Frequently Asked Questions
Can I use the BM1366AL in a Bitaxe Ultra build?
Yes. The Bitaxe Ultra is designed around the BM1366 chip family. The BM1366AL is a BM1366-family chip and works as a direct drop-in for Bitaxe Ultra builds. You’ll get the same 5nm efficiency and hashrate performance as any other BM1366 variant on the Bitaxe platform.
What’s the difference between the BM1366AL and BM1366BS?
Both are BM1366 family chips built on the same 5nm process. The AL variant is the specific chip used on Antminer S19 XP hashboards, while the BS variant is used on Antminer S19k Pro hashboards. For ASIC repair, use the variant that matches your machine. For Bitaxe Ultra builds, either variant will work.
Are these chips new or pulled from used machines?
These chips are sourced from brand-new equipment by D-Central’s technicians. They have not been run in production mining operations. You’re getting fresh silicon that hasn’t been thermally cycled through months of 24/7 hashing — which matters for both repair longevity and Bitaxe build reliability.
I think my S19 XP has a bad chip — can D-Central repair it for me?
Absolutely. D-Central has been repairing ASIC miners since 2016 and maintains 38+ model-specific repair pages — including dedicated S19 XP repair services. We’ll diagnose your hashboard, identify every failed chip, replace them, and test the board before shipping it back. If you’d rather have a professional handle the reflow and diagnostics, that’s exactly what we do.
How many chips does a single S19 XP hashboard use?
Each Antminer S19 XP hashboard contains a large array of BM1366AL chips working in series. If one chip fails, it typically takes the entire chain offline — which is why even a single bad chip can knock out significant hashrate. When diagnosing, check your miner’s kernel log for ASIC errors pointing to specific chip positions on the chain. That tells you exactly which chip needs replacing.
