Hardware Notes Specification Details ASIC chip marking KF1978E Compatible miner families Whatsminer M50S, M60S, and M63S series Algorithm SHA-256 Typical related symptoms Chip ID error, bad chip detection, domain instability, low hashrate, overheating-related faults Availability Not sold separately; installed only as part of repair service 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. Contact our repair team today and get your miner back to full power.
