Antminer chipset BM1397 chip has three models: BM1397AG/BM1397AD/BM1397AI. They are suitable for Antminer S17, S17pro, S17+, T17, T17+. BM1397AI is universal with BM1397AG and BM1397AD. The difference lies in frequency and temperature. In theory, replacing 2-5 chips of the same model with different suffixes on a single Hash board will not have a substantial impact.
