Description
Restore your Antminer S19k Pro to full mining capacity with a genuine replacement hashboard from D-Central Technologies. The S19k Pro uses BM1366 ASIC chips — Bitmain’s highly efficient SHA-256 silicon — and losing even one of its three hashboards means a significant hit to your daily output. Our professionally refurbished boards are tested under load and ready to drop in.

BM1366 — Bitmain’s Efficient Silicon
The S19k Pro is powered by BM1366 ASIC chips, delivering one of the best joules-per-terahash ratios in the S19 family. These hashboards maintain that efficiency advantage, meaning your replacement board will not just restore lost hashrate — it will do so at the same power efficiency the S19k Pro is known for.
Professionally Refurbished
D-Central’s repair technicians inspect every hashboard for dead ASIC chips, cold solder joints, damaged voltage regulators, and worn connectors. Failed components are replaced with genuine Bitmain parts. The board is then tested under sustained load to verify stable operation across all chips before it ships to you. This process produces boards that are often more dependable than factory-new units, because every potential failure point has been proactively addressed.
Drop-In Installation
This is a direct replacement for any of the three hashboard slots in the Antminer S19k Pro. Remove the failed board, install this one, reconnect the data ribbon cable and power connectors, and the control board will detect it automatically. No firmware changes, no configuration adjustments — just restored hashrate.
Also Ideal for Custom Builds
S19k Pro hashboards are excellent candidates for single-hashboard builds using the Loki DIY Kit. With a single board, a Loki Kit, and an appropriate PSU, you can build a compact, lower-wattage Bitcoin miner perfect for home use. The BM1366 chip’s efficiency makes these boards particularly well-suited for dual-purpose mining and heating setups.

Frequently Asked Questions
Can this hashboard be used in other Antminer models?
No. S19k Pro hashboards are specifically designed for the S19k Pro and are not interchangeable with other S19 variants (S19, S19 Pro, S19j Pro, etc.), which use different ASIC chips and board layouts.
How do I know if my hashboard needs replacing?
Check your miner’s web interface. If it reports fewer than 3 detected hashboards, or if one board shows significantly lower hashrate or frequent ASIC chip errors, the board likely needs repair or replacement. A hashboard test fixture can provide a definitive diagnosis.
What is the warranty?
D-Central provides a 7-day DOA warranty. If the board arrives non-functional, contact us immediately. Shipping costs for warranty claims are the customer’s responsibility.
Do you also offer repair service for S19k Pro hashboards?
Yes. If you have a failed S19k Pro hashboard you want repaired rather than replaced, D-Central offers professional ASIC repair services. Contact us for a diagnostic assessment and repair quote.
