Chip-Maker AMD has admitted that a bug is causing slow PC performance or stuttering issue with some Ryzen chip-based PC systems.

AMD is working on a permanent fix that should arrive in early May, after several users reported PC performance issues on online discussion forum Reddit..

The US-based company 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.

“As an immediate solution, affected customers dependent on fTPM functionality for Trusted Platform Module support may instead use a hardware TPM device for trusted computing,” AMD said in a support document.

AMD said that fixing the problem will require a motherboard system update.

“Check with your system or motherboard manufacturer to ensure that your platform supports add-in dTPM modules before attempting or implementing this workaround,” AMD said.

The users will need full admin access to perform the workaround.

“If you don’t want to go through the process of buying and installing a TPM chip, you can wait for AMD’s flashable customer system BIOS files to become available in early May,” AMD said.
