Vendors have started releasing new BIOS updates that restores the TSME feature on consumer Ryzen CPUs.
ASUS Releases ComboAM5 P1 1.3.0.1b Patch A to Restore TSME Feature on Non-PRO Ryzen CPUs After AMD Promised to Reinstate it
A week ago, users complained that their Ryzen CPUs were no longer showing TSME support. This was due to the latest AMD BIOSes, which reportedly removed the TSME encryption feature on the Ryzen CPUs. However, AMD didn't remove it from the PRO variants and told MSI that the TSME is reserved only for the Ryzen PRO chips.
TSME, or Transparent Memory Secure Encryption, is a feature that encrypts the data stored in the system RAM using a processor-generated key during boot. This works automatically once enabled in BIOS and prevents cold boot attacks. Since this wasn't a major feature for the masses, AMD quietly removed it, but due to the community backlash, it announced that it would reinstate the feature through the upcoming BIOS updates.
As of today, one of the popular AMD board partners is seen to have released the new patch that fixes this problem. As spotted by @unikoshardware, ASUS has released its latest BIOS update that contains the AMD AGESA 1.3.0.1b patch. The release notes state that this update restores the Transparent Secure Memory Encryption feature.
Hence, AMD Ryzen chip owners with ASUS motherboards can download the latest Beta BIOS 2401 on their 800 motherboards to restore the feature. This won't affect users who haven't upgraded to every user, as systems with AGESA BIOS 1.2.0.7 and above were affected by AMD's removal of the TSME feature. Hopefully, we will see other vendors releasing their latest patches soon as well.
