BM1746AA ASIC Chip for Antminer Z15 Zcash Hashboard Repair

BM1746AA: selection and compatibility guide

BM1746AA, also searched as BM1746, is a replacement hashing ASIC for the original Antminer Z15 Equihash hashboard. It is intended for component-level Zcash miner repair. This listing does not establish compatibility with Z15 Pro, Z15K or Bitcoin miners. Match the marking on the failed chip and the actual board revision before ordering.

Plan a reliable Zcash miner repair

Identify whether the problem involves the complete power supply, control board, hashboard power circuit or hashing chip before selecting a replacement. A low hashrate reading alone does not identify the failed part. Record the miner model, board number, firmware version and relevant error messages. Clear photographs of the installed assembly and component markings make a replacement request easier to assess.

For ZEC mining operations, keeping a model-specific spare-parts list can simplify maintenance planning. Separate original Z15 parts from Z15 Pro selections, and keep revision information with each line item. Hardware that looks similar may use different voltage settings, connectors, programmed data or firmware. A product photograph is a reference for identification and does not replace the supplied unit label or a confirmed bill of materials.

BM1746AA: frequently asked questions

Is this a Z15 Pro chip?

Compatibility here is limited to the original Z15 reference. A similar model name is insufficient to establish Z15 Pro fit. Send a readable chip photograph and board number for separate confirmation.

What information should I send for a compatibility check?

Send the miner nameplate, readable front and back photographs of the relevant board or power supply, full component marking, required quantity and destination country. For a repair kit, include the desired component list. For a controller, include the existing platform and firmware requirement. For a power supply, include the input voltage and complete output-label specification.

Does replacing a part guarantee restored hashrate?

No. Repair results depend on the diagnosed fault, the remaining circuit condition, installation quality and subsequent testing. A replacement component does not provide an independent hashrate increase. Test the repaired assembly with the appropriate equipment and manufacturer procedures before returning the miner to sustained operation.

How should installation be handled?

Use a qualified technician for electrical and board-level work. Disconnect power and follow the applicable isolation, discharge and electrostatic precautions. Component rework requires suitable tools and an appropriate temperature profile. Do not use a product description as a substitute for a model-specific repair procedure. Inspect connections and cooling before a controlled return to service.

Reference model information can be compared with the supplier product reference. Match the quoted batch rather than assuming all revisions are identical. Explore the Antminer Z15 Pro Zcash miner y mining accessories when preparing a complete maintenance order.

Request BM1746AA availability from PunkHash with model, quantity and destination. Confirm the final unit price, included items, packaging, lead time and applicable warranty in the quotation. Freight, import charges and delivery arrangements depend on the destination and shipment; a product listing does not establish local stock or a fixed delivery promise.
