How to choose the right ASIC chip for Whatsminer hash board?

During the repair of Whatsminer miners, selecting the ASIC chip that matches the hash board batch number is a precise and necessary task. The ASIC chip replacement principle for Whatsminer hash boards is different from that of Antminer hash boards. When replacing the Whatsminer ASIC chip, you must select the corresponding ASIC chip model according to the batch number of the hash board. This is not only related to the performance of the miner, but also to the quality of repair. Below we will explore how to choose the correct ASIC chip based on the batch number.

Check the batch number of Whatsminer hash board

Whatsminer miners will have a batch number on the hash board, and this number indicates the type of chip on the board. We can find the last seven digits of the batch code on the label on the surface of the hash board.

Chip selection comparison table

A key tool is the chip selection table, which lists the relationship between different lot numbers and the corresponding chip suffixes. With this table, you can easily find out which chip model you need. For example, the KF1930 chip table states that for hash boards with batch numbers from 01A to 05E, the KF1930-03C model chip should be selected for replacement, and the suffix 03G is used to repair hash boards with batch numbers from 01F to 05M.

How to efficiently select the corresponding chip?

According to the hash board selection table of multiple ASIC chips, we can get the rules of the hash board batches corresponding to Whatsminer KF19** chips:

Conclusion

The correct chip selection ensures the smooth maintenance of the Whatsminer and the stable operation of the Whatsminer. By following the matching rules of batch number and chip model, you can effectively perform hash board repair and ASIC chip replacement of Whatsminer, improving repair efficiency and quality.
