AMD removes memory encryption from consumer Ryzen CPUs, sparking user backlash
Ars Technica reports that AMD has removed Transparent Secure Memory Encryption (TSME) from consumer Ryzen CPUs via AGESA firmware changes, a move not publicly announced. Tests showed TSME was enabled on older firmware but not on newer AGESA 1.2.7.0 on consumer boards, while PRO/enterprise CPUs retain the feature. The change prompts questions whether it was a deliberate policy restriction or an unintentional regression, with AMD not providing a clear explanation. Security experts say there should be an official rationale behind withdrawing a longstanding memory-protection feature.
