Do you using software 2D switching because of multi display setup?

This flickering on multi display setups is exactly the reason why nvidia does not full idle in this situation automaticly. This will not change on custom bios either. Its some strange behavior when using GDDR5 and lowering the memory clock while multiple displays are connected. Nvidia stated to this and sayed this is hardware limitation wich isn't fixable!

There are further impacts if you change P3 state memoryclock/voltage to different than P0. This will make impacts on software overclocking and voltage control.

If it were that easy nvidia or some aibs would already have done that. ;-)
