Core Voltage showing wrong in CPUZ

After having to get a new motherboard and AIO I decided I would try my hand at over clocking again.   Running a 6700K on an MSI Z270 M7 board with a H100i v2.  Its a long story why I am running a 6700K on a Z270 board.   

Here is my Issue  Cpu - Z is not showing the core voltage that I set in the UEFI BIOS.  its show almost too low to be stable.   

 

Highest stable I have gotten 

XMP on 3200mhz Corsair 16 X 2 kit

Multiplier = 46

Bclk = 102

Core Voltage 1.4 (I Know this is high)

Power management feature is off <- don't remember the exact name

This all adds out to be 4693 MHZ almost 4.7ghz OC  @ ~80c running real bench stress test for 15mins.   

 

The Odd thing is CPUZ is showing 1.168V that is a big difference from 1.4v.    I know the voltage is going up when i increase it in the Bios.   As I can see temps go up and more stability.

that's vdroop. Voltage goes wayyy down when there's load to prevent noobs from breaking their stuff.

 

also, dont play with BCLK so much. Doing that just adds another cause if instability.

 

Detailed video if you have time
