Sorry: no way to do it under Linux, unless you find a modded BIOS that suits your particular 7970 model, and you flash it.

Wait, maybe I'm not understanding here. Are you saying that with Ubuntu you're using more power than with Windows 7? Sounds good to me.

I mean no tools to lower voltage so impossible to save some electricity.If no solution yet MODERATOR PLS CLOSE THREAD.
