AMD chipset driver fixes Ryzen CPPC2 issues on Windows 11

AMD Ryzen Processor

Job half done! If you are an AMD lover and using a Ryzen processor on your Windows 11 machine, then you have reason to be pleased. That’s because the company has released a new chipset driver.

Version is the one you are looking for, and it comes with a performance patch for an issue in the new operating system that caused it not to properly schedule the fastest available cores appropriately.

The was due to a problem with the Collaborative Processor Performance Control (CPPC) mechanism that resulted in applications that were not highly threaded lose performance on Windows 11.

AMD notes in the release notes:

“Restores intended function and behavior of UEFI CPPC2 (“preferred core”) in Windows® 11 build 22000.189 (or newer) on AMD processors.”

The driver also adds a new Ryzen Power Plan that comes optimized for Windows 11, which should fix this CPPC2 problem once and for all on devices rocking Ryzen CPUs.

And while this new driver patches performance issues on Windows 11, it is also available for the older Windows 10 on all Zen based systems. On the newer OS, it is only compatible with Zen+ processors and newer, which makes sense as that operating system only supports Zen+ and newer CPUs.

In terms of chipset support, though, all Zen based chipsets are supported by this new driver.

Obviously, only part of the job is done here.

That’s because, upon release, two issues were discovered for Ryzen processors on Windows 11. This first one is fixed, but the other one that hampered performance due to L3 cache latency still needs to be taken care of.

Hopefully, that too is not far off.
