Alright, so far after slighty moving my back plate I get:
1.202 CPUz
1.25 DMM (A nice RS unit, yes I just said nice and radioshack in the same sentence lol)

I will try HW info right now.

I am watching and waiting smile.gif what are you using for load?

Hwinfo is reporting VID,not Vcore.
VID - what is the voltage the motherboard things the CPU needs.
Vcore - actual vcore supplied.This is offset +/- the VID wink.gifHere,read it (Click to show)
VID is (and if an engineer wants to correct me, go ahead) the VCore a given CPU tells the motherboard to give it at stock settings, and may be different for each processor. It's "stamped" in at the factory, and both AMD and intel chips of the same model can have completely different VIDs.

Newer CPUs have dynamic VID for turbo modes, so when the CPU upclocks, the core voltage increases as well.

In newer intel chipsets (2011 and 1155 for example) you can either set a fixed VCore for your OC (stays where you set it, no matter if your CPU is loaded or idle) or set an offset to the VID. The offset adds or removes some voltage from the VID of the chip, depending where you set it, but the voltage still increases with load and decreases when idle.
If you don't believe me,scroll down in Hwinfo to to the point where you'll see Vcore.It'll be the same as in CPU-Z.

P.S. Really sorry for misleading information,i've been running 4.3Ghz on 1.120V,not 4.4Ghz.

Waitig to see that! I bet CPU-z with Ivy Bridge CPU's and pretty much with all CPU's isn't that off.Maybe the OP got a dud motherboard,i don't know.Sin's review is reporting the CPU-Z readings being off by 0.03-05,not .01V or even more.

Alright, some interesting results with Hwinfo.

The separate core VIDs are all around 1.225V. I am doing all these tests under load so there is some variation.
The vcore is reading at 1.208V still.

The BIOS is set to 1.225V with LLC at level 2,

Thanks for the clarification hot wheels! Maybe this is not the workaround I was hopeful for. Although was a lot closer to actual for me.

When set at 1.45V DDM reads 1.487 and CPUz reads 1.424 so around .06V diff from each other but both are off from the set 1.45............

Can you set at 1.45V in BIOS and check with DMM while gaming.I bet it would be around 1.43-4V while CPU-z would be reading the same 1.424.

Oh this is disturbing. Does anyone know if this affects other asrocks boards as well? I am planning on buildnt a mini-itx rig in the near future and the asrock z77e-itx was my planned motherboard.

It's at about 1.46 while gaming. LLC still at level 2. CPUz still reads 1.424.

Sin any thoughts?

He is right, VID is not your actual VCore, it is just a number for each multiplier that offset voltage is based on.

Like I posted before, I won't be changing for another Extreme 4 board again so I cannot test if it is the same issue with another board aswell so I'm hoping others with the Extreme 4 and Extreme 6 are able to measure their VCore aswell to provide some actual numbers for it aswell.
