AMD Restores TSME Encryption to Ryzen CPUs After 1 Week of User Backlash

Summary
AMD reversed course on consumer Ryzen security, saying Transparent Secure Memory Encryption will return after users objected to its quiet removal.
TSME encrypts all data in system memory, blunting cold-boot and other physical-access attacks that leave stolen RAM contents unreadable.
The feature had been dropped through a recent firmware update rather than a silicon change, making the rollback largely a software decision.
AMD had offered TSME on consumer Ryzen chips for years, and criticism intensified after the company initially declined last week to explain or acknowledge the change.
