[update]

Power differences are significant enough to justify the effort.

running at 900/750@0.925v my card draws 142w
running at 900/150@0.925v my card draws 125w

running at 1100/950@1.055v my card draws 236w
running at 1100/150@1.055v my card draws 200w

Dropping the vmem voltage from 1.6 down to 1.5 nets about 2-4w when running at higher memory speeds (700+)
but doesnt do much at lower 150mhz speeds (less than 1w, well within the scope of inaccuracy of my power meter)

kind regards

Do you believe this will work with radeon 69xx cards not dropping memory below 150 of core too? I seen a lot of people complaining about this.
