As far as I know it doesn't, I have both "Unlock voltage control" and "Unlock voltage monitoring" enabled and I see no voltage at all, so I guess not.
But as far as I know my 2nd HD6970 (The black one with blue pcb) is non-reference, or at least, I think so, since PCB is not the same, if you check my build log, I have a reference + non-ref, but not like I care much either.
