en.Wedoany.com Reported - ASUS has begun rolling out beta BIOS updates for multiple AM5 motherboards, becoming one of the first to restore support for Transparent Secure Memory Encryption (TSME), marking an early implementation of AMD's promised fix. Previously, AMD faced criticism for quietly removing this security feature from non-Pro Ryzen CPUs.
According to VideoCardz, these beta BIOS files cover the ROG Crosshair, ROG Strix, TUF Gaming, and ProArt series motherboards based on AMD's X870, B850, and X670 chipsets. The firmware was shared by overclocker SAFEDISK via the ASUS ROG forum, including support for "GNR Transparent Secure Memory Encryption," where GNR refers to the AMD Ryzen 9000 desktop CPU family (Granite Ridge).
These BIOS updates are based on AGESA ComboAM5 PI 1.3.0.1b Patch A, released earlier than AMD's previously stated July timeline, restoring TSME support for non-Pro Ryzen 9000 processors. Specific versions include BIOS 2401 for most X870 motherboards, BIOS 1686 for B850 motherboards, and BIOS 3901 or 3886 for X670 motherboards depending on the model.
AMD officially confirmed to Tom's Hardware last week that, after receiving "valuable community feedback," it would restore memory encryption for Ryzen 9000 CPUs via BIOS updates. Previously, AMD users expressed strong dissatisfaction over the company's removal of TSME support from non-Pro CPUs. TSME is a security feature that protects the CPU from physical attacks by encrypting data stored in memory, making the data inaccessible to physical attackers.
The incident began when a user discovered that the feature was unavailable on their Ryzen 7 9700X system, despite being enabled in the BIOS. Further tests involving MSI motherboards showed that consumer-grade Ryzen chips could report TSME support under older firmware but failed to do so after newer AGESA updates, while Ryzen Pro processors continued to support it. Following extensive feedback, AMD initiated a fix and set a timeline to restore the feature via BIOS updates in July.
ASUS's current update indicates that the fix has been implemented ahead of AMD's July timeline, making it one of the first motherboard manufacturers to integrate the restored feature into actual motherboard firmware. However, these are still beta BIOS versions shared via the ASUS ROG forum, not widely stable releases. Users who specifically need TSME may need to monitor closely, while those running production or stability-critical systems are advised to wait for the final official BIOS.
