Thanks msgclb. 0x0C is equal to 12 decimal so MSR 0x198 does seem to contain the multi for Core i7 but not much of anything else that I can see.
With Core 2 Duo/Quad when you used CPU-Z and went into the cpuz.ini file and set
Sensor=0
it would report VID instead of your core voltage. That's the number zero and not the letter O. If it is set to 1 then it reads and displays your real time Core Voltage in that box.
Can you give that a try to see if CPU-Z can be used to report VID for Core i7 users? So far, Core Temp and RealTemp are in the dark about VID for Core i7.
With Core Duo based processors, VID and multis could be found in MSR 0x198
but Intel has obviously moved where the multi is located and eliminated the VID data in here. They are allowed to do stuff like this without issuing any documentation of the changes. By using the word Reserved throughout their documentation, that allows Intel to change the meaning of MSRs however they like, whenever they like. We call this, "a monopoly"![]()
