Hey! Yesterday I stumbled upon the problem of not being able to enable unofficial OC in MSI Afterburner. This happened after reinstalling Windows.
Thanks to Unwinder for giving us an explanation for the problem!
AMD has removed two dll files in Catalyst 12.2 that still existed in version 12.1. Therefore if 12.2 happens to be the first driver you install on your new system you won't have those two dll files on your computer. This causes MSI Afterburner to fail to set the unofficial overclocking values.
To fix the problem you need to download the two dll files and place them in your MSI afterburner folder. You may need to REBOOT afterwards.
The files can be downloaded here:
Do this at your own risk. This solution might or might not work with future Catalyst releases.
Confirmed working on Catalyst 12.2.
Confirmed working on Catalyst 12.3.
Confirmed working on Catalyst 12.4.
Confirmed working on Catalyst 12.8.
This method still works with Afterburner 2.2.2. I cannot confirm if recent versions still support this method. Make sure that both of your config files have these lines at the bottom.

The cfg files are located at:
If you are having problems try to disable third party themes, that worked for me.
