I have a problem installing the driver 16.11.4 and after a reboot windows 10 pro changes the driver degrades it to 16.6 as I can solve many thanks
I have exactly the same problem I did not understand.
But it works with 16.6
I don't recommend keeping 16.6, as I know, it has a fan controller bug, which either stops the fans or spins them at 100% randomly (the first one is worse).
