AMD has removed the Transparent Secure Memory Encryption (TSME) feature from its lower-end Ryzen CPUs, which previously provided protection against cold boot attacks and other physical exploits. TSME was initially introduced in high-end CPUs and later included in consumer models. The change was made without prior notice, making it difficult for users to detect on Windows systems and requiring technical knowledge for Linux users. AMD has not provided a reason for the removal and confirmed that TSME is now only applied to PRO CPUs as part of AMD PRO Technologies.
