Whatsminer KF1968 KF1968E ASIC Chip for M50 M50S M30S++ Hashboard

Whatsminer KF1968 / KF1968E ASIC Chip | Drop-In Replacement for M50, M50S and M30S++ Hashboards

The KF1968 / KF1968E is the hashing ASIC chip used on Whatsminer M50, M50S and M30S++ hashboards. Each chip is a single point in the long serial chain that runs the length of the hashboard — when one chip fails, the chain reports incomplete, the affected hashboard drops to a low or zero hashrate, and the miner logs missing-chip errors. Swap the failed chip out, reflow the chain, and the board returns to normal duty.

Direct drop-in replacement — same package and pinout as the chip originally fitted at the factory. Stocked in volume for repair shops servicing M50 / M30 fleets and individual miners replacing failed chips at the bench.

When to Replace the KF1968 / KF1968E

• Hashboard reports low or zero hashrate — chip chain incomplete on one board while other boards run normally.
• Chip count mismatch in the chain scan — diagnostic tool flags the failing position.
• Visible damage on a chip — burnt, cracked, or delaminated package after thermal stress or transient event.
• Single-board failure after a known fault event — short, power surge, or coolant intrusion likely killed one or more chips along the chain.

FAQ — KF1968 / KF1968E ASIC Chip

Q: KF1968 vs KF1968E — interchangeable?
A: Same chip family for the same hashboard positions on M50 / M50S / M30S++. The "E" suffix denotes a production revision — match the silk marking on your existing chips when possible to keep chain-level matching tight.

Q: How do I identify which chip in the chain failed?
A: Use an ASIC chip tester or hashboard test fixture that scans the serial chain and reports the position of the first failure. Once the failing position is known, locate that physical chip on the board, desolder, and fit a fresh KF1968 in its place.

Q: Rework profile?
A: Standard hot-air rework with flux paste, preheat the board to 100°C before applying hot air, peak around 320°C with controlled dwell time. A precision tin tool / stencil for the KF1968 footprint makes chip placement repeatable across multiple repairs.

Q: Bulk pricing for repair shops?
A: Yes — email contact@lys-sz.com for volume pricing on KF1968 chip stock and matched tin tool / stencil kits.
