AMD will reinstate memory encryption on Ryzen 9000 CPUs via BIOS update in July

AMD will reinstate Transparent Secure Memory Encryption (TSME) on Ryzen 9000 desktop processors via a BIOS update in July, reversing its removal in an earlier firmware update. The feature, which encrypts data in RAM to protect against cold boot attacks, was quietly disabled in AGESA 1.2.7.0 earlier this year, prompting community backlash and a bug report from a security researcher. AMD confirmed it is bringing the capability back to consumer CPUs "based on valuable community feedback."
