HW Info Vcore Discrepancy?

I noticed that there is a motherboard Vcore and a CPU Vcore section under HWinfo and was curious as which one is the actually Vcore:

The ones under the motherboard section seem incorrect to me. Is this right and normal?
I am running stock voltages(Bios voltage settings on Auto) at the moment with XMP enabled (i7 4790K @ 4.4ghz on all cores and RAM at 1600mhz dual channel).
 
Hi Archer27, the actual core voltages are represented by vcore#, 0-3 (0 is the first core, 1 the second etc). Vcoreprefin is a measure of voltage supplied to the cpu but the cpu has an internal voltage regulator so it's not the voltage going to the cores. Vid is another value preset at the factory and is not core voltage.

Here's a screenshot of your pictures with green arrows pointing to your vcore values.

Different brands/models of motherboards read the data differently, for instance on yours it shows 4 values and the vcore for each individual core. I have a different z97 board and using hwinfo64 it only outputs one value for 'vcore' to represent all 4 cores.
 

Ahhh ok, thank you for the clarification.
Is there any reason why my mainboard is "overvolting" my CPU then? I mean if the CPU is requesting a certain value and the MOBO is providing it something different, is there a reason for that? As I said, BIOS is all stock but the XMP switch is on, so all cores are set to run at 4.4ghz and RAM at 1600.
