AMD Ryzen Chipset Driver Release Notes

As promised by AMD_Robert, over on reddit last week, a new chipset driver lands today that promises to fix the driver install issue.

Earlier today AMD finally put out a chipset driver that resolves a bug that has plagued the last two releases of their chipset drivers. Earlier last week AMD_Robert posted a message on the AMD reddit page stating that this patch was on the way. Which was a welcomed message and a trend I hope continues long after their recent driver issues.

Release Highlights

  • Removed deprecated device IDs from the IOV driver
  • Removed deprecated device IDs from the USB 3.0 driver
  • General system stability improvements

Fixed Issues

  • Installer may hang during installation progress
  • Installer may abort with “Error 1720” code
  • Installation will not install on a non C:\ location
  • Resolved screen rotation bug with select AMD mobile processors
  • Rare system halt on 7th Gen AMD A-Series APUs

Known Issues

  • Windows Installer pop up message may appear during install
  • Moving installer window during install process may cause installer window to flicker/move around the screen
  • Cannot open installation log file after completion
  • Installer may not update a sub-package to the latest version
    • Workaround: Manually uninstall any prior sub-package, reboot, then re-install the full Chipset package

Installation of Software

Note: Close all opened applications before attempting the install process.

  • Unzip and extract the deliverable folder ‘AMD_Software_<Version>.zip’ containing:
    • Release Notes
    • Installation Executable
  • Double click and invoke the installation executable named ‘AMD_Chipset_Software.exe’.
  • Provide administrative privilege explicitly if prompted for, by clicking ‘YES’ in the UAC prompt.
  • By default, the executable extracts files under “C:\AMD\Chipset_Driver_Installer \AMD_Chipset_Drivers” and “C:\AMD\Chipset_Driver_Installer \ChipsetDriversExtract” to continue with installation.
  • Any driver specific file changes can be made under ” C:\AMD\Chipset_Driver_Installer \AMD_Chipset_Drivers\IODriver \<DriverName>”
  • Re-run the executable and continue with above mentioned steps to select any more drivers to de deployed on the system.

Uninstallation of Software:

  • Once installation completes successfully, uninstallation can be done by clicking ‘Uninstall’ after selecting on ‘AMD Chipset Drivers’ entry in control panel which removes all uninstall-able drivers deployed via ‘AMD_Chipset_Software.exe’ from the system.

Note: To give better user experience, AMD UART, AMD GPIO & AMD I2C Drivers were made as non-uninstall-able drivers from ‘AMD Chipset Drivers’ entry in control panel, even if deployed on the system
