AMD to Fix 'fTPM' Stuttering Issues on Ryzen CPUs, But Patch Is 2 Months Out
AMD has confirmed that some Ryzen CPUs can stutter when the fTPM module onboard the chip is activated. The company is working on a fix, but it won’t arrive until “early May” or possibly later, depending on the motherboard vendor, AMD said in a new support document.
For months, AMD users have reported stuttering problems that can temporarily slow down a PC for a few seconds. This can occur while running a video or playing a game, as the clips below show. Users have said the stuttering can happen a few times a day or once a week.
Customers began experiencing the problems after enabling the fTPM module on the Ryzen CPUs. The component is essentially AMD’s firmware-based implementation of the Trusted Platform Module, a security feature that’s designed to securely store your login information and handle encryption processes on the machine.
Most consumers had never heard about TPM before last year, when Microsoft made the security chip a requirement to run Windows 11. As a result, numerous AMD users began digging into the motherboard’s BIOS systems to enable the fTPM module in preparation to run the new OS.
According to users, the stuttering issues can affect both Windows 11 and Windows 10, provided the fTPM module on the Ryzen chip is activated. It remains unclear which Ryzen CPUs are affected, but AMD's support document blames the stuttering on faulty “memory transactions.”
“AMD has determined that select AMD Ryzen system configurations may intermittently perform extended fTPM-related 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 is concluded,” the support document notes.
