AMD Releases New Ryzen Chipset Software With Installer Overhaul and Bug Fixes

AMD continues its busy streak with a new Ryzen chipset driver release. After denying delays for its Instinct MI455X and adding support for Alibaba’s Qwen 3.5, the company has now rolled out an updated chipset package for Ryzen systems.

According to TechPowerUp, AMD has released Ryzen Chipset Software version 8.01.20.513, bringing general bug fixes and performance improvements aimed at enhancing overall system stability.

Ryzen Chipset Software 8.01.20.513 Brings General Improvements

The latest chipset update focuses on:

• General bug fixes
• Performance optimizations
• Quality-of-life improvements for Ryzen CPU users

While AMD did not outline specific performance metrics, the release targets smoother operation across supported AM4 and AM5 platforms.

New Install Shield Wrapper

One of the more noticeable changes arrives in the installer itself.

AMD has updated the package with a new Install Shield installation wrapper. This change may improve compatibility and installation reliability across different Windows environments.

However, the update also modifies how certain drivers are handled.

AMS Mailbox and S0i3 Drivers Removed From Package

Version 8.01.20.513 no longer bundles:

• AMS Mailbox driver
• S0i3 filter driver

Systems that rely on these drivers must now install them separately. Failing to do so could trigger errors on affected configurations.

AMD also notes that AMS and S0i3 filter drivers may experience issues on non-English operating systems.

Ongoing Regression Issue Between Driver Branches

AMD confirmed an ongoing regression problem between chipset driver branch version 7 and version 6, and users who install version 7.xx.xx.xx or later cannot directly downgrade to version 6.xx.xx.xx or earlier.

Workaround Steps:

1. Uninstall the newer chipset installer.
2. Navigate to the Chipset_Software directory.
3. Delete the “Qt_Dependencies” folder.
4. Install the older 6.xx.xx.xx (or earlier) version.

Without these steps, the downgrade process may fail.

Known Issues

AMD also highlights several known limitations:

• Some driver names may appear in English on non-English operating systems.
• Ryzen PPKG may occasionally fail to install or upgrade.
• AMS and S0i3 drivers may encounter installation issues on localized Windows builds.

These notes suggest the company continues refining compatibility across global system configurations.

A few days earlier, AMD also published a new optional Adrenalin graphics driver, so you might want to download it as well.

With chipset software 8.01.20.513 now available, Ryzen users may want to review AMD’s release notes carefully before updating, especially if they plan to downgrade or rely on specific driver components.
