As someone pointed out to me in another thread - looks like they found the source of the HD6000 series "underclocking".
Ironically it's associated with the UBI animation at the beginning of the non-Russian version. Basically there are instructions around to tell you how to disable the animation which will restore an HD6000 series to life.
You just delete it
