Summary
AMD is reinstating Transparent Secure Memory Encryption (TSME) on its Ryzen 9000 desktop CPUs through a BIOS update in July 2025, after quietly removing the feature earlier this year via AGESA firmware update 1.2.7.0. The feature, branded as Memory Guard on Ryzen PRO chips, was removed from non-PRO CPUs but is being brought back due to community feedback. AMD confirmed the move to Tom's Hardware, stating the feature will return with a new AGESA version.
