anyone noticed how annoyingly the 1st gpu clock varies when DOWNvoltaging the card?(6950), even though powertune is set to +20%, when adjusting the voltage(in AB), the closer to 1.1 volt i set (<1.1) the lesser the clock fluctuations.. When i stress test them with occt gpu, the 2nd card stays at full clock, but the 1st varies between 561 and 800mhz

edit:
found a "quick and dirty" way to avoid this bug (dunno if happens to others though)
Set the desirable voltage in afterburner, move the powertune slider to -20% for both cards, APPLY, then move again to +20% for both, APPLY, and gpu1 clock now is constant.

edit2: it doesnt happen with 1 vga in the system, i can adjust every secodn a new value to voltage, and during occt gpu gpu clock stays solid.
