Update:

Apparently Unwinder was allowed by MSI & AMD to incorporate a workaround for the DLL files that AMD removed from Cat 12.2+. As an added bonus this has been rolled into MSI Afterburner 2.2.0 Final Edition!!! And since the next gen AMD cards are also supported in the final edition, "Unofficial Overclocking" will be available to use for some time to come.

You can download MSI Afterburner 2.2.0 Final from Guru3d (Here) or MSI (Here)

Happy Overclocking
