It does change. SpeedStep or C1E changes it - it doesn't change the vCore.
Enable them and run Orthos with CoreTemp running.
This happens with *all* chips. There is no "max VID".
VID is the voltage your motherboard gives to your CPU when vCore is set to auto. SpeedStep and C1E change it between two values (one being the default, and one lower) when enabled.
This is probably because they are CPU features, not MB features. Sure, the motherboard needs to support them too (which probably means supporting a variable VID), but the motherboard doesn't do the work (I'm betting it can't see the % load each core is under)
It's something internal within the CPU, and I bet that it's also effected by the load on each core.
f.e. if you only have one core at 100% and the other at 0%, the VID might stay on the lower value.
