ASUS AM5 BIOS Update Restores TSME for Ryzen 9000 Non-PRO CPUs

Users building or upgrading desktop PCs with AMD Ryzen 9000 processors can now restore hardware-level memory encryption on ASUS motherboards. The update restores a security feature that allows users to encrypt memory on standard desktop processors. The restoration of this capability matters because it allows standard desktop users to access enterprise-grade protection without switching to specialized PRO-series chips.

Beta firmware restores enterprise-grade memory encryption for standard desktop processors

ASUS has released beta BIOS updates for AM5 motherboards in the ROG Crosshair, ROG Strix, TUF Gaming, and ProArt series. The updates apply to systems using X870, B850, and X670 chipsets. The update coincides with AMD's decision to restore TSME support for non-PRO Ryzen 9000 processors.

• TSME Support: Restored for Granite Ridge (Ryzen 9000) non-PRO CPUs
• Supported Chipsets: X870, B850, X670
• AGESA Version: 1.3.0.1b Patch A

The firmware includes AGESA version 1.3.0.1b Patch A, which enables TSME for Ryzen 9000 non-PRO CPUs. The firmware enables Transparent Secure Memory Encryption, a feature previously limited to professional AMD processors. The included AGESA update allows the motherboard firmware to support the memory encryption requirements for TSME.

Different BIOS versions are assigned to each chipset to support the updated firmware. X870 boards receive BIOS version 2401, while B850 models update to version 1686. X670 systems use either BIOS version 3901 or 3886 depending on the specific board revision. These version numbers indicate that ASUS has begun distributing firmware patches to support the restored encryption capabilities.

ASUS has released beta BIOS updates for its AM5 platform motherboards, covering ROG Crosshair, ROG Strix, TUF Gaming, and ProArt series models. These updates target systems built on X870, B850, and X670 chipsets, ensuring broader compatibility across the current generation of AMD sockets. The firmware rollout aligns with AMD's recent decision to reintroduce Transparent Secure Memory Encryption, or TSME, to non-PRO Ryzen 9000 processors.
