AMD recognizes system hiccups in Windows due to firmware TPM and is working on a solution
AMD recognizes that users of Ryzen CPUs may experience system hiccups if they enable the firmware TPM on Windows 11 and Windows 10 PCs. The company is working on a solution in the form of a bios update that should be released from early May.
According to AMD, the hiccups are caused by certain Ryzen system configurations sometimes making extended memory transactions with motherboard SPI flash memory, which is related to the fTPM. The hiccups last until the memory transactions are completed. The issues are fixed in Agesa version 1207, which will be introduced in new bios versions. The first updates are expected to be released by motherboard manufacturers in early May. The exact release date varies by motherboard.
Until then, those users who need TPM functionality can switch to a dTPM hardware module, AMD says. However, this is not possible on all motherboards or systems. Users must purchase a suitable module for their motherboard themselves. AMD recommends users switching to a dTPM to back up their data first. Also, users should disable any disk encryption that uses the TPM, such as BitLocker.
TPM support is officially required in Windows 11, although that requirement is not yet strictly enforced by Microsoft. There is no TPM requirement for Windows 10. Users have been reporting hiccups due to fTPM on AMD systems for some time. For example, a YouTube user posted a video demonstrating the issue in January. Tom’s Hardware writes that the issue occurs on AM4 systems with Zen+ to Zen 3 CPUs.
