Hashboards

Hashboards are where the actual Bitcoin mining happens — arrays of ASIC chips performing trillions of SHA-256 calculations per second. When a hashboard fails, you lose a third (or more) of your machine's hashrate. D-Central stocks replacement hashboards for Bitmain Antminer and MicroBT Whatsminer miners, tested and ready to ship.

Our hashboard inventory covers popular models including:

Antminer S9 — Still one of the most deployed miners worldwide, widely used in space heaters
Antminer S17 / T17 — Known for hashboard failures; we carry tested replacements
Antminer S19 / S19j Pro / S19 XP — Current-generation boards
Whatsminer M20 / M30 series — MicroBT replacement boards

Every replacement hashboard is bench-tested on a known-good control board and PSU before it leaves our workshop. We verify hashrate output, chip count, temperature readings, and error rates. No dead boards, no surprises.

Diagnosing a hashboard issue? Common symptoms include missing hashrate (one or two boards not detected), ASIC chip errors in the kernel log, abnormal temperature readings on specific boards, or the dreaded "chain not found" message. Our ASIC Repair Cost Estimator can help you decide whether to replace or repair.

For board-level repair (individual chip replacement, trace repair, connector resoldering), our ASIC Repair Service handles it all in-house. Need chips for your own repair? Browse our ASIC Chips inventory.
