Help me beat my Manual OC score with Undervolt and PBO!


I had some questions and need some answers.
Please examine all of this and help me figure out what I should do.

CPU: Ryzen 7 2700x
Motherboard: Gigabyte X470 Aorus Gaming 7
BIOS version: F4g

It did 4GHz stable at 1.32V with Medium LLC with manual OC
4.1GHz was only stable at 1.4V least

Did a manual OC across all cores with:
Vcore to 1.4V
Medium LLC
And it only helped me reach 4.1GHz.
4.2Ghz was asking for more than ~1.45-1.5V
XMP profile for ram set to Profile 1 (3600MHz)
Cinebench score - 4121 (Highest so far in my tests)
Nothing failed in prime95 test too

F4g is the version that has a PBO Scalar setting
It was removed from newer versions of BIOS for some reason

My old temps (no oc) were definitely more than this before I undervolted. They were around ~90c and idled around ~70c

Overvolting helped me a lot? but,
PBO is not able to push above 3999 or 4000 on load
It pushes 4.32GHz on idle on one of the cores for some reason
Temps are definitely better
And I beat my previous 4GHz manual OC score in cinebench too

PBO Settings:

PPT 1000
TDC 114
EDC 168
vCore Offset -0.1v
MediumLLC (both)
3600MHz XMP Profile 1 on RAM
Max Temp Reached 84.5C
Idle Temps ~50-60c
Cinebench Score - 3929

I've chosen the max values that Ryzen Master showed for (PPT, TDC, EDC)
I've set all of the values through BIOS.

The Undervolt looks pretty stable but I feel like I could do better and I'm missing a main point here.

I used 3 softwares CPU-Z, HWiNFO and Open Hardware Monitor and the readings do differ in each of them.

I've included all the pictures of after OC (load and idle) and cinebench scores
And the pictures of the BIOS settings I was talking about
Please take a look at them here:

I'm new to OC and messing with BIOS but I really like it!

So can someone please help me understand why it isn't pushing above that 4GHz or 3.9Ghz on PBO?

How can I improve the performance?

And most importantly help me beat that manual OC 4.1GHz Cinebench score!

Thank You!
