Some time ago AMD's Ryzen processors had lagging and crashing problems under Microsoft Windows 11, and the same situation has appeared on Windows 10. After months of investigation, AMD has identified the cause as being related to the motherboard's SPI ROM, and has promised to release a new version of the BIOS in May to fix the problem.

The problem was previously thought to be related to fTPM - as long as fTPM is turned on in AMD platforms there may be periodic crashes, lag, system instability, crackling sound playback and screen mouse fidgeting, etc. Disable fTPM and these problems will disappear.

AMD's investigation confirmed that the root cause of the problem lies in the SPI ROM flash memory on the motherboard of the Ryzen platform. The Ryzen's configuration may allow it to intermittently perform extended memory transactions associated with fTPM, which may cause system interactions and responses to pause.

AMD offers a temporary solution by switching the system's fTPM settings to dTPM. the latter uses NVROM to interact with TPM, but only if the user's device supports the dTPM feature, and switching TPM means that encryption needs to be replaced to ensure that one's data backup is okay. 

Of course, the ultimate solution is to upgrade the BIOS. AMD said that a new upgrade patch will be released in early May this year, which may be based on AGESA 1207 or higher version of the microcode, the specific plan is to wait for the motherboard manufacturer's test and upgrade results.
