From what I've seen is the adaptive voltage (load line calibration) can work in this way.
1. intel spec for vdroop
2. disabled where you don't have any voltage drop and keep a static voltage both at idle and load
3. Allows for vdroop at different levels (marked as positive percentages on the new boards)
4. Added vcore over idle when loads are applied (marked as negative percentages on the new boards)
5. Auto function. The bios adjusts vdroop according to you overclock. Probably for people that don't want to screw with it.
The only problem with adding vcore to to idle voltage under load is that when the load is removed, there is a voltage spike that could kill you CPU at very high offsets. Make sure you know Vmax for you CPU so that you don't do that. Nice thing about the dark is that it has a probelt you attach to the MB to get real time voltages.
You asked about idle voltages and how offsets affect that. From what I've seen in my own experiments, the idle voltage increases only a fraction with each incremental change in offset towards adding voltages under load. I mean minimal. like 0.001 - 0.002 volts. (I could also be misinterpriting that as voltage ripple since it varies based upon process that are occuring the background like OS system resources) far as I can tell, idle voltages are not effected with subtraction or addition of vdroop after set in the bios. I have not experimented with increased vdroop and how that affects idle vcore. Might do that soon. I'm predicting it won't matter.
