Just like this, I believe 'VID' goes down once you apply tinkered oc settings.
iirc, before I mess with anything in bios, HWinfo reports the VID for an 1800x being 1.55v and it doesnt move. after messing with stuff VID is maxing at 1.35 with lowest being .886 (vid of pstates) and applying my offset from there, which is then reported in voltage readouts below, maxing at 1.512 with 0.15 offset.
I think since offsets and other bios settings settings don't get returned to default when a post fails, but pstate gets lost and since frequency target in extreme weaker isn't touched, VID will return to default but still have your offset applied thus resulting in much higher voltage than you desire.
One possible yet probably undesireable work around is to setup bios with the lowest CPU speed you can do without having to increase the offset, then use one of the windows softwares to raise the speed/offset to what you want. These don't actually change bios so when you crash from something or get post fails, no crazy offsets will be applied to the default VID.
