AMD Ryzen Chipset Driver 5.02.19.2221: optimizing the use of Ryzen 7000X3D series processors
AMD has released version 5.02.19.2221 of the Ryzen chipset driver, which is compatible with the corresponding chipsets of various Ryzen processors, including the A320, B350, X370, B450, X470, X399, A520, B550, X570, B650E/B650, X670E/X670, TRX40, and WRX80 platforms running Windows 10/11 operating systems.
In the new driver, AMD has fixed some driver errors on the Ryzen platform, and more importantly, has added support for the new Ryzen 7045HX series and Ryzen 7000X3D series processors that use 3D vertical cache (3D V-Cache) technology.
The Ryzen 9 7950X3D and Ryzen 9 7900X3D, which are already on the market, are both dual CCD models. Compared to regular processors, the L3 cache capacity has increased by 64MB, which means that only one CCD has added SRAM. For this asymmetric configuration, AMD has promised to work with Microsoft to ensure that the Windows operating system can recognize the differences between the two CCDs and better allocate tasks.
In addition to targeted optimization of the operating system and a series of software, AMD also dynamically allocates the kernel required by the Windows operating system through the new Ryzen chipset driver. If the workload is sensitive to cache, the operating system will be modified to prioritize the CCD with increased SRAM to maximize the large cache performance advantage of the Ryzen 7000X3D series processor.
Known issues include:
- Sometimes custom install fails to upgrade to the latest drivers.
- A manual system restart is required on Non-English OS after the installation is complete.
- Uninstall summary log may incorrectly show uninstall status as failed on non-English OS.
Users of the new Ryzen processors who want better performance optimization are advised to update the Ryzen chipset driver to the latest version. The AMD Ryzen chipset driver version 5.02.19.2221 can be found here.
