I've been having a bit of a fiddle with the voltage settings, specifically vcore, to see how low I can take the vcore on my i5 750 at stock speeds (spec in sig). I've noticed that when the vcore is set to auto, it goes all the way down to 0.848V when idle and up to 1.23V ish at load. If I set the vcore manually (currently down to 1.06875V) then the idle voltage never goes below 1.024V. I know its not a massive difference but how come auto can take it lower than a manual setting?
Why does auto vcore have a lower idle vcore than manual settings?

At Load - Full vcore
Idle - Powersave vcore
I didn't explain it properly but I had all of the power saving functions on when I was using auto Vcore and when I set it manually. It just seems odd that with auto Vcore, when speedstep lowered the multi at idle, it lowered the Vcore down to 0.848V. If I manually set the Vcore as low as it can go (1.06875V), when speedstep lowers the multi at idle, it only drops the Vcore down to 1.024V. I would have thought it would have dropped the Vcore to 0.848V like auto does, but it doesn't seem to be the case.
Also forgot to mention that this was with llc setting set to standard which supposedly follows the Intel spec. I've also noticed that there is an option called Dynamic VID which I think was only added in the latest F6 Bios for the board. The option is greyed out though so I'm not sure what it does or whether it works with the i5's or whether its just something for the i7 8xx.
