Unfortunately I can't find any scaling factor for VSB3 voltage. Sometimes in7 = 5.98, sometimes in7 = 4.44 or even 3.91, and I can't see any regularity for this values.
Still no ideas about this in7 parameter. :(

My motherboard uses intel g2020 processor with nominal core voltage 0.92V. Core voltage displays as 0,86V in lm-sensors by default.
In BIOS power management menu core voltage displays as 0.92V, In my guess we needs a "+0.06" correction for this.
Maybe I'm wrong.

I used several reverse engineering tricks from this wonderful article:

Yes, this is my mistake.
Thank you for your comments and recommendations.
