Known Issues

• After installing the AMD Chipset Installer version “7.xx.xx.xx”, users cannot install version “6.xx.xx.xx” or earlier.
  Workaround:

  • Delete the “Qt_Dependencies” folder located at "C:\Program Files (x86)\AMD\Chipset_Software\".
  • Install any older version of the AMD Chipset installer (version 6.xx.xx.xx or earlier).

Although there is now an AMD Chipset Driver Set with a higher version number 7.12.04.858 available, the v7.11.26.21242 seems to be the latest (compiled and signed on 04. December).

That's odd because 7.12 also dates from December 4th.

 

 

Nothing odd
AMD_Chipset_Software_7.11.26.2142 package digital signed November 27, 2025, the included AMD_Chipset_Drivers.exe dated and signed from November 27, 2025
AMD_Chipset_Software_7.12.4.858 package digital signed December 4, 2025, the included AMD_Chipset_Drivers.exe dated and signed from December 4, 2025

Now it's getting complicated:
AMD_Chipset_Software_7.11.26.2142 from AMD s complete but partly older drivers included.
AMD_Chipset_Software_7.12.4.858 is not complete from a mainboard manufacturer, but partly newer drivers included.
Missing drivers in 7.12.4.858: AS4, CIR, NULL Driver for Microsoft Pluton Security Processor 2, OEM Provisioning, PMF_Ryzen_AI300SERIES2, PMF_RyzenAI300Series, PMF_RyzenAIMAX300SERIES Driver, SFHI2C and USBFilter driver.
