My understanding is that it will still behave as if it were set to "Auto," but give the offset amount of voltage as well. So if your default voltage at stock clocks is 1.15V and the offset is +.15V, it will start at 1.3V and still go up from there as your CPU starts using Turbo multipliers. Say your CPU decides to turbo up to 4.5 GHz on an expected core voltage of 1.35V, it will end up getting 1.5V instead.

I have my own question as well. When I OC'd my Q6600 to 3.402 GHz (9x378) I would set my VCore to 1.4075V. While idle it would SpeedStep down to 2.268 GHz (6x378) and 1.1625V. My 2600K is OC'd to 4.8 GHz on 1.376V, but at idle the system speedsteps down to 1.6 GHz and remains at the same voltage. Can this type of behavior be achieved anymore? I guess the offset would be similar but less exact.
