The pesky fTPM bug that affected a wide range of AMD Ryzen systems has been finally addressed by AMD. This widely-known issue that caused performance dips, mainly in the form of stuttering in games has been fixed in the recently rolled out AGESA V2 1207 microcode update already available for most AM4 boards. In addition to the 400 and 500 series motherboards, the older 300 series A320, B350, and the X370 chipsets have also gotten the fix.
AMD states that the fTPM-related memory transactions in the motherboards’ SP1 flash memory were likely the culprit. When fTPM is enabled in the BIOS on AMD Ryzen systems, there is a verification delay between Windows and the fTPM memory transfer in the background. As a result, the performance would suffer, often resulting in sporadic stutters and freezes as well as jittery audio. In extreme cases, primarily on lower-end systems, this can even cause crashes.
This problem affected Ryzen PCs running both Windows 10 and 11, but since fTPM is mainly a requirement for the latter, the former was largely unaffected. In addition to this, stability issues affecting the Ryzen 7 5800X3D have also been fixed. The BCLK FSB overclocking is now supported, although the multiplier is still locked to avoid any damage to the extra cache.
