Users cry foul after AMD stripped memory crypto from its consumer CPUs
AMD silently dropped Transparent Secure Memory Encryption (TSME) from consumer Ryzen chips starting with AGESA 1.2.7.0, where the internal DfIsTsmeEnabled flag now returns FALSE for consumer SKUs and TRUE only for PRO and EPYC parts, leaving protection against cold boot attacks, DRAM snooping, and memory module removal undetectable on Windows and hard to spot on Linux. A privacy-conscious Linux user traced the regression after HSI flagged “encrypted RAM: not supported,” and MSI engineering confirmed AMD told them TSME is exclusive to PRO processors, though AMD has never publicly clarified whether this is deliberate policy or a firmware bug. That distinction matters operationally since one is a permanent tier restriction and the other is fixable, so anyone relying on TSME on consumer silicon should treat the protection as gone until a firmware audit proves otherwise.
