There are no problems with the chipset driver itself that I have seen, only with the
installer, which even in the updated chipset driver version (which supposedly had all of the installer issues from the March version rectified), unfortunately, the installer still lists the failure to install the GPIO system driver as a "known issue," for some reason. Why AMD made an official announcement about the new chipset driver install program being fixed, only to include the same GPIO driver install failure (even after reboot) as a "known issue" beats me...
It's difficult to understand, because in the earlier chipset driver installers (used for chipset versions prior to the March release), the GPIO driver installed fine, as did the other drivers. So..."drop back to the old installer while you iron this out" would be my advice to Robert.
The good news is that all of the chipset drivers can be installed manually without a problem. Be sure, though, if you do this to read the .rtf readme for the chipset driver revision. It tells you which of the included chipset drivers are applicable to your operating system version--something the installer would normally do for you automatically. For instance, even though the chipset driver package includes a custom AMD "SATA" driver, it is only intended for Win 7 installations and is literally several years old...
In Win10, AMD is using the standard SATA drivers from Microsoft for your HDs. For my Win10 system, only five of the included drivers are used by my AMD x570 chipset mobo.
