BM1397AH can replace the chip: BM1397AG BM1397AI BM1397AD

Refit Antminer S17 series miner heat sink to save maintenance costs

Antminer BM1397 BM1397AH chip supports the SHA256 algorithm, which can be used for mining encrypted digital currencies such as BTC and BCH, and will be used for the next-generation SHA256 algorithm of the new Antminer S17 and T17. BM1397 adopts global TSMC FinFET technology, integrates more than 1 billion transistors on a single chip, and is continuously optimized in circuit structure and low power consumption technology. The energy efficiency ratio of BM1397 is 30J/T. The high-quality Antminer BM1397AH can replace the damaged chips on the S17, S17+, S17Pro, T17, T17+ hash board. Please note that we recommend replacing a maximum of 5 damaged chips per hash board.

Brand new official accessories, genuine guarantee.
