The Antminer BM1397 BM1397AG chip supports the SHA256 algorithm, which can be used for BTC, BCH and other encrypted digital currency mining, and will be used in the next-generation SHA256 algorithm of the new Antminer S17 and T17. BM1397 adopts global TSMC FinFET technology, a single chip integrates more than 1 billion transistors, and has been continuously optimized in terms of circuit structure and low power consumption technology. The energy efficiency ratio of BM1397 is 30J/T. The high-quality Antminer BM1397AG can replace damaged chips on S17, S17+, S17Pro, T17, T17+ hash boards. Please note that we recommend that each Hash board only replace 5 damaged chips at most. Of course, Antminer BM1397AD and Antminer BM1397AI can also replace damaged chips of S17, S17+, S17Pro, T17, T17+ hash boards. These three kinds of chips are universal and can be replaced with each other.
