- AMD has released the newest version of its chipset driver, as well as a performance fix for Windows 11.
- The CPPC method had a bug, leading the release version to incorrectly schedule available cores.
- There was also a problem with L3 cache latency.
AMD Ryzen CPU customers using Windows 11 are in for a treat, as the firm has released version 3.10.08.506 of its chipset driver.
To top it off, it will be released with a performance fix for a Windows 11 problem. Due to a Collaborative Processor Performance Control (CPPC) mechanism, the OS had a difficulty correctly scheduling the fastest available cores.
Problems with performance
As a consequence of the vulnerabilities, applications that had not been threaded were suffering performance difficulties.
There was also a latency problem with the L3 cache, which was most noticeable on Zen CPUs.
AMD claims, according to the release notes, that
- On AMD CPUs, the original function and behavior of UEFI CPPC2 (“preferred core”) in Windows 11 build 22000.189 (or newer) has been restored.
- The chipset driver includes a revised Ryzen Power Plan 220.127.116.11, which is optimized for Windows 11 and should solve the CPPC2 issue.
The updated driver fixes performance problems on Windows 11, but it’s also accessible on all Zen-based computers running Windows 10.
The hitch is that the driver is only compatible with Zen+-based CPUs and newer for Windows 11. If you’ve been following the progress of Windows 11, you’re aware that it has system requirements.
The driver also provides support for 4Mbps baud rate and fixes an OpenGL error pop-up by downloading a new AMD UART Driver version 18.104.22.168.
Issues that have been identified
The following are some of the problems that have been identified:
- There is a problem with custom installs not updating to the newest drivers.
- Text alignment problems exist in the Russian language.
- After finishing the installation on a non-English OS, a manual system restart is needed.
- During the installation, a Windows Installer pop-up notification may occur.
- On non-English OS, the uninstall summary log may show an erroneous uninstall status as fail.
- A pop-up warning “AMD Chipset Software is not responding” may appear when the installation is started and the UI screen is displayed.
On AMD’s official website, you may download the latest 3.10.08.506 chipset driver.
