● Sometimes custom installations cannot be upgraded to the latest driver.
● There may be text alignment issues in Russian.
● After the installation is complete, non-English operating systems require a manual system restart.
● Windows® Installer pop-up messages may appear during the installation process.
● On non-English operating systems, the uninstall summary log may incorrectly show the uninstall status as failed.
The latest AMD chipset driver is available for all motherboards compatible with Zen-based processors (Ryzen, Athlon and Threadripper), including A320, B350, X370, B450, X470, X399, A520, B550, X570, TRX40 and WRX80 chipset.
Although all motherboards with AM4 and TR4/sTRX4 sockets support Windows 11, first-generation Ryzen and Threadripper, seventh-generation AMD A-series, and Ryzen 2000G are not officially compatible with Microsoft 's latest operating system. Still, users can bypass these restrictions using a popular utility called Rufus.
