If you are experiencing stuttering issues on your AMD PC, check your motherboard’s support page to see if there is a new BIOS available. A newer AGESA version, 1207, is intended to address performance issues with some Windows PCs, so it can resolve any issues you are experiencing.
This specific stuttering problem has been reported (opens in new tab) from the beginning of the year, and was later determined to be related to the Firmware Trusted Platform Module (fTPM), which is a key part of the Windows 11 system requirements.
If you want the full technical breakdown of what’s going on, AMD assigns (opens in new tab) a system intermittently running “fTPM-related extended memory transactions in SPI flash memory (SPIROM) located on the motherboard, which can lead to temporary pauses in system interactivity or responsiveness until the transaction completes”.
Basically fTPM was holding everything else back.
AMD promised later BIOS updates that would contain improved modules for fTPM interaction with SPIROM to resolve the issue, starting in May 2022. And now these BIOS updates are relatively easy to obtain as hardware.info (opens in new tab) grades.
I’ve checked some of the major manufacturers – Asus, MSI, ASRock and Gigabyte – and all but one (ASRock) offer the latest AGESA version in a BIOS update. ASRock offers up to AGESA 1206b today and we hope it won’t be long before they also release the later version.
Most of the time, it’s just a matter of updating your own motherboard’s BIOS for a fix today.
You want to check your motherboard’s support page for the new BIOS. It will be labeled as providing support for AGESA 1207. You will likely want an external drive or USB flash drive on hand for easier BIOS updating, although some motherboard manufacturers may allow you to update over the Internet as a secondary option.
