your gpu is NON-GCN! so you cant use the latest drivers
just use latest LEGACY-Drivers or what AMD suggests
use DDU and install 16.2.1 NON-GCN driver!
you have a bug in your version that was fixed later
simply run DDU in safe-mode and clean your driver
than install 16.2.1 (NON-GCN) Crimson beta or use latest Legacy-Driver
then it will work!
AMD Radeon Software Crimson Edition 16.2.1 Beta for Non GCN Products Release Notes | AMD
here this is the last/latest (maybe - because its beta) working driver or your GPU
As per the screenshot, I see that the current installed version is showing as 15.301.1901, which is nothing but the internal driver version of 16.2.1, so both are same.
Refer this release notes - AMD Radeon Software Crimson Edition 16.2.1 Beta for Non GCN Products Release Notes | AMD
Copied from the release notes -
So, the current driver installed on your system is 16.2.1. so there is no need to update the driver again. It just confusing you. Ignore the driver update notification and continue to use it.
