First off I am in a little bit of confusion in terms of my Vcore voltages. I am getting 3 different readings and am not sure which one to go off of. HwMonitor shows 1.37 vCore. Cbut a little further down I have a voltage known as VIN0 that bounces around from 1.368-1.389v as well. I am assuming it is another core voltage reading because it is almost spot on with the other two. My question is which voltage should I go off of?

Secondly, To keep CnQ I have to use offset voltages in the BIOS(otherwise CnQ is overridden the cpu stays at 100% voltage at all times) and it seems that I don't have that fine tuned control over voltage I had when I just plugged in values with my old motherboard. I am in the process of using different combos of offset voltage and LLC settings to try and achieve those "grey areas" of voltage that I can't achieve with offset alone(with offset, I have options to + or - in increments of .00625 but for example with a setting of -.00625 load voltage hovers at 1.368-1.382 under load depending on which program I am looking at. If I go another tick down to -0 aka, auto, load voltage is as high as 1.42-1.44v, cpu LLC is set to high) Why are the differences in voltage so high? where did everything in between the stated voltages go?
Any ideas? or tips and tricks in using offset voltages? Or am I missing something with CnQ not working when using standard values for voltage? I am having a harder time overclocking and fine tuning my overclock with this high end board in comparison to my older motherboard. Maybe its just the fact that I have so much more control over everything. But any and all help would be much appreciated
EDIT: Also, when I go through and set my frequencies in the BIOS. It shows me a target frequency, which is what I am trying to achieve, and a "current frequency" which ends up showing 50mhz higher than my target. what is this and why?
use HwMonitor vCore or better use ASUS AI Suite II V1.02.03 download from asus
as the cpu loaded varies it will need more or less voltage and the board will vary the voltage with the auto features it will compensate as needed
when overclocking and loading the cpu it consumes more current and therefor you will get a voltage drop as the load increases
the LLC when set higher will compensate for the voltage drop as the load on the cpu varies the voltage will vary
i like to use offset with + or - voltage and then set the LLC to compensate for voltage drop
the most important part is to keep the cpu temperatures below maximum factory spec
with auto setting the board will have a tendency to set to maximum
there is some auto overclocking and balancing built into the board hence the increase in frequency
