Question More accurate vcore on Ryzen 7950X3D ?

[splfh0000]

I got a new Ryzen 7950X3D CPU, and wanted to take more on performances and about the vcore.

7950x3d had two ccd, one is 3dcache ccd and another one is just normal one.
The problem is, two ccd's vcore should total difference,
3dcacah ccd vcore should not over 1.2v and normal should not over 1.4v, based on the information that I found online.
So, is this completely correct? I think there is something wrong after few testing.

First, sometimes I got my vcore over 1.2v on 3dcache ccd, even I tried pull down the "curve".
And the second things is, sometimes two ccd is running "together", at the meantime the reading of vcore is based on the higher one(normal ccd),
This will make the reading of vcore to be very high, I can't read the ccd0's vocre reading normally.

So, some people said on the Internet, the vcore of 7950x3d is OK even over 1.2v,
that is because the reading at that time was on ccd1, not ccd0.

I want to know if there is a better way to clearly separate the two sets of ccd readings without mixing the two sets of things and displaying them together.
And, although there is no definite proof, but should ccd0 really be limited to 1.2v?
Thank you.
