Adrenalin 21.3.2 and older version have this problem
Normal memory without OC is 2000, You can push it up to 2150. That setting KEEPS getting stuck.
I try to type in the default and nothing. I try to move the slider back to default and nothing.
It is one thing after another with these new cards and sorry but I am starting to get a bit fed up with all the bugs.
The clock itself does not get stuck at that frequency.
