    Note

    AMD CPU Platform Secure Boot (PSB) fusing is a one-time operation that permanently binds the CPU to genuine Lenovo firmware to enhance platform security and cannot be reversed. The CPU can only be used in Lenovo servers once fused. AMD and Lenovo recommend PSB fusing if the CPU will only be used in Lenovo servers.
