AMD has released an update for its Ryzen processors to address critical vulnerabilities and improve stability. The update primarily targets the proprietary security technology, Platform Security Processor (PSP), which is integrated into AMD’s processors. This technology is responsible for various security mechanisms built into your processor.
The update includes critical security patches for PSP, as well as fixes for AMD MicroPEP drivers, which manage transitions between power states and clock speeds. While some speculate that the update may improve performance, this has not yet been confirmed by AMD.
Security experts recommend installing the update due to its significant enhancement of security features. The update is available for all common Ryzen motherboards and processors, including X570, B550, A520, and others.
To download the update, visit AMD’s website and select your motherboard chipset and processor socket (all use AM4). Ensure you choose the correct chipset for your motherboard.
Before installing, search for “System Information” in Windows 10 to determine your motherboard’s chipset. Administrator rights are required to install the software, and it is recommended to uninstall the old version if available.
