How to select the BM1368<\/h3>\n
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.<\/p>\n
Diagnose the equipment before ordering<\/h3>\n
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.<\/p>\n
BM1368 installation planning<\/h3>\n
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.<\/p>\n
Buyer questions about BM1368<\/h3>\nWhat information does PunkHash need for a quotation?<\/h4>\n
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.<\/p>\n
Are condition, delivery and warranty fixed for every order?<\/h4>\n
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.<\/p>\n
Does replacing the BM1368 guarantee that the miner is repaired?<\/h4>\n
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.<\/p>\n
Prepare a matched BM1368 order<\/h3>\n
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.<\/p>\n
