AMD Restores TSME to Ryzen 9000 Chips via BIOS Update After Backlash

Summary
AMD said it will bring Transparent Secure Memory Encryption back to non-PRO Ryzen 9000 consumer chips through a new BIOS update after users discovered the feature had been removed.
TSME encrypts data stored in system RAM with a processor-generated key, helping defend against cold-boot attacks that require physical access to the machine.
The reversal followed criticism that AMD had stripped the feature silently in a recent AGESA firmware update, leaving even some motherboard vendors unaware until users saw TSME marked unsupported.
AMD told Tom's Hardware the change was driven by “valuable community feedback,” turning a transparency dispute into a policy reversal on consumer chip security features.
