I am using the Ryzen 7 2700x CPU on MoBo Asrock B450M-HDV on O.S. Windows 10 Pro X64. After the last update of Bios, version 3.10, I disable the SMT for it, but they are still active. I try to disable the SMT by Bios and also by the AMD Ryzen Master App, but it is still active. I removed and reinserted the MoBo battery, returned to Mobo to the factory settings and tried to disable the SMT, did not solve.
