BM1368 ASIC Chip for S21 Hashboard Repair

BM1368: reliable repair-part selection

BM1368 is available for sourcing through PunkHash for matched ASIC miner maintenance. BM1368 is an ASIC chip family associated with selected S21 and S21 Hydro hashboard revisions. The family includes PB, PA, PM, PV and AA markings in supplier listings; these suffixes need explicit matching for each repair order.

BM1368 identification and application

How to select the BM1368

The reference photograph shows a PB-marked package. Send the complete original marking and board number when requesting PA, PM, PV or AA alternatives. This page does not promise that every suffix is a direct substitute on every S21 board.

Diagnose the equipment before ordering

An unstable hashrate or missing-chip error does not by itself prove that the ASIC is defective. A repair technician should distinguish the suspect component from power-domain, signal-chain, solder-joint and surrounding-circuit faults before replacing it. Avoid ordering a chip solely from a machine-level symptom.

BM1368 installation planning

Use suitable ESD handling and a qualified board-repair process. Confirm package orientation and board condition before installation. After repair, document the relevant board test and a monitored miner run so a recurring system fault is not mistaken for a successful component replacement.

Buyer questions about BM1368

What information does PunkHash need for a quotation?

Send the miner model, full installed part marking, board or PSU revision, clear connection photographs, required quantity and destination country. For a mixed order, list each model and revision separately. This makes it possible to identify the requested hardware without treating similar-looking parts as equivalent.

Are condition, delivery and warranty fixed for every order?

No. Ask for the selected batch condition, included items, final price, dispatch plan and warranty in the quotation. A reference photograph shows the product family and does not establish the condition or package contents of every available batch. Shipping charges and import requirements depend on destination.

Does replacing the BM1368 guarantee that the miner is repaired?

No. The replacement must match the diagnosed fault and the installed hardware. Confirm the exact configuration before payment, retain the original part identification and document the repair result. A correct part number is an important selection step, but it is not a substitute for diagnosis.

Prepare a matched BM1368 order

For an international repair order, include your delivery country and postal code so the quotation can address the shipment rather than assume a universal freight cost. Farm operators should also identify the installed miner variants and keep separate spare-part records for each revision. Send model, quantity and destination for quotation.
