AMD reversed its April move that silenced Transparent Secure Memory Encryption on consumer Ryzen chips. The change, pushed through an AGESA update bundled with motherboard firmware, aimed to limit TSME to commercial Ryzen PRO, Threadripper WX, and EPYC lines. Users caught the shift when BIOS options vanished.

TSME uses silicon‑level hardware to lock memory content, echoing Intel's TME‑MK on Core consumers. By disabling the feature, AMD left many home users without a built‑in encryption layer that could protect data against hardware snooping. The decision sparked backlash on forums and among security advocates.

Responding to community pressure, AMD said it will re‑enable TSME in a July UEFI update. The hardware exists across Ryzen consumer and Ryzen PRO CPUs, so the restoration will simply unlock an existing capability rather than add new silicon. The move reaffirms AMD’s stance on security for its mainstream line.

The July firmware release will bring back a BIOS toggle that had been removed from 9000‑series desktops. AMD confirmed it will not drop TSME from Ryzen PRO processors in the future. Home users can now expect the same encryption protection that commercial customers already enjoy.
