AMD backpedaled on its recent decision to remove Transparent Secure Memory Encryption (TSME) feature on its consumer Ryzen processors, which was typically enabled by default. The company had, in April, quietly disabled the feature for Ryzen consumer processors through an AGESA update encapsulated into motherboard firmware updates. The idea probably was to restrict TSME to Ryzen commercial-segment processors, sold under the Ryzen PRO brand, besides Ryzen Threadripper WX workstation processors, and EPYC server processors. For reference, Intel offers a similar feature, TME-MK (Total Memory Encryption-Multi-Key) on even its consumer Core processors, and not just its commercial Core vPro processors.

AMD said that it has decided to restore TSME "based on valuable community feedback," and end-users should expect UEFI firmware updates that restore the feature starting next month (July 2026). TSME is a hardware-based feature that leverages fixed-function hardware on the silicon to encrypt the contents of the memory, providing an additional layer of security. Since AMD shares a common IOD design across its Ryzen consumer and Ryzen PRO commercial product lines, the feature is physically present.
