The Mac said:This CAT is missing the SDK, this causes all kinds of weird behavior if you try to cleansweep/atiman to remove prior CATs.
The simplest solution is to install 12.1 for none 7xxx users or before, then install this RC right over the top allowing CAT Manager to handle uninstalling necessarily components.
This will fix the AB OC issues, as well as the GPU-Z cat reporting issue...
The only thing ive found wrong with this release is after a length of time, powerplay ignores any unlocked vcore increases, and reverts to the bios default causing GPU resets if youve upped vcore and not flashed it to the bios.
