🧩Add-on to a repair, not a standalone item. We do not ship chips — the chip is installed on your board during the repair.
Every hashboard repair includes a set number of chip replacements; the number is shown on the repair page for that board. This add-on covers replacements beyond that number.

The final count is known only when the repair is complete.
USA-based repair lab (no outsourcing)
🔬Component-level diagnostics and repair (ASIC chips, LDOs, power circuits, SMD parts)
🔥Burn-in testing under load before return shipment
▸How to ship your hardware
📍Ship to: Antminer Repair LLC, 2141 NE 51st Ct, Apt E, Ft. Lauderdale, FL 33308
📝Put a printed note inside the box — your name or company, return address, phone and email. Without it the repair can stall.
🫧Hashboards: at least 8 layers of bubble wrap on every side, reinforced corners, sturdy sealed box. No sealed air pillows — they burst in transit.
📦Whole miners: original packaging with foam inserts if you have it. No cables or accessories — anything that is not packing material is not returned.
📨After shipping send us the tracking number, package weight and dimensions.
⚠️Damage caused by improper packing is not covered by the warranty.

KF1978E ASIC Chip Compatibility and Service Use

What This Chip Is Used For

The KF1978E is an ASIC chip used on MicroBT Whatsminer M50S, M60S, and M63S series hashboards. In repair work, this chip is relevant when diagnosing chip ID errors, bad chip detection, unstable domains, low hashrate, overheating damage, or board communication issues.

Important Purchase Note

This item is not sold separately. We do not ship loose KF1978E chips for DIY repair, resale, or third-party installation. KF1978E chips are supplied and installed only as part of an approved hashboard repair service performed by our repair lab.

When KF1978E Replacement May Be Needed

  • Whatsminer reports chip ID errors such as “SMX reading chip id error.”
  • The hashboard is detected but cannot reach the expected hashrate range.
  • One or more domains become unstable after warm-up or under full miner load.
  • The board has overheating history and suspected weak solder joints under one or more chips.
  • The miner reports bad chip, board communication, or ASIC-chain related faults.

Why We Do Not Sell KF1978E Chips Separately

KF1978E replacement requires proper diagnostics, controlled soldering, thermal restoration, and real miner load testing. Replacing the chip without confirming the actual failure can leave the original problem unresolved, especially when the fault is caused by LDO output, solder joint damage, signal-chain interruption, connector damage, or surrounding components. This is why KF1978E chips are supplied only as part of our repair service, not as loose parts.

Technical FAQ

Q: Can I buy a KF1978E ASIC chip separately?
A: No. We do not sell KF1978E chips as standalone parts. They are used only as part of our Whatsminer hashboard repair service.
Q: What Whatsminer models use the KF1978E ASIC chip?
A: KF1978E ASIC chips are used on Whatsminer M50S, M60S, and M63S series hashboards.
Q: Is the KF1978E chip used on Whatsminer M60S hashboards?
A: Yes. The Whatsminer M60S hashboard version we service uses KF1978E chips. One known M60S board configuration has 215 chips per board, arranged as 43 domains with 5 chips per domain.
Q: Why is KF1978E chip replacement not offered as a DIY part?
A: KF1978E replacement requires diagnostics, precision soldering, thermal restoration, and real miner load testing. A chip ID error can also be caused by LDO faults, solder issues, signal-chain problems, or nearby components, not only by the chip itself.
Q: Can you install a KF1978E chip during Whatsminer hashboard repair?
A: Yes. If diagnostics confirm that a KF1978E chip needs replacement, we install it as part of the approved Whatsminer hashboard repair service.
Q: Does a Whatsminer “SMX reading chip id error” always mean the KF1978E chip is bad?
A: No. That error may point to a failed chip, but it can also come from weak solder joints, local power issues, damaged signal paths, connectors, or other components on the hashboard.
