The 10.12a are the 6xxx which use a different driver branch for the 10.12a, so the error was yours in this case.
Actually like i stated in the comments above, if you go to AMDs website and navigate to the 6900 series drivers, those are the ones it tells me to download, not the updated ones. In this case the obvious error is the one who's listing the drivers, AMD.
