You need to modify the .ini file of the AMD Chipset to have it install in a AMD Motherboard with a Non-AMD GPU card. This answer has what you need to do from a previous thread:Cant install tr4 chipset driver amd-chipset-drivers_18.10_feb error 173 ????
There is a bug in AMD Chipsets that prevents it from installing on a AMD motherboard with a Non-AMD GPU Card installed. I have the same problem but there is a workaround for it. This is the Thread that explains all the problems people are having with this issue but it does give a workaround fix in being able to install AMD Chipsets on a AMD motherboard with a Non-AMD GPU card installed: https://community.amd.com/message/2843147?q=Raid%20chipset .
Sometimes updating the BIOS and Motherboard (if it is Intel) Chipsets helps with newer AMD Drivers to install correctly.
