AMD restores memory encryption on Ryzen 9000 CPUs after removing it

AMD will reinstate Transparent Secure Memory Encryption (TSME) on consumer Ryzen 9000 processors via BIOS update in July. The company had quietly disabled the hardware feature before launch, drawing criticism from security-conscious users and developers. TSME encrypts DRAM contents at the memory controller, mitigating cold-boot and physical extraction attacks. AMD cited community feedback for the reversal, a rare instance of consumer pressure reversing a firmware decision typically shaped by enterprise tiers.
