Bad Vdrop Z370 Pro4

Hi

29 years old that I'm overclocking, never seen a Vdrop as bad!
My 8600K at 5ghz under stresstest Orthos, the vcore is between 1.392 and 1.454
Fix in bios at 1.42v is almost the same

I do not understand that a CM with 10 phases can have a Vdrop as bad.
It looks like it uses only 6 phases because the 4 of the top do not heat up.

I tried a lot of tuning and impossible to be stable in h24 at 5ghz, I am really very disappointed.
Since I overclook, I had to buy more than 100 motherboards, first time I buy Asrock and I think it's the last one.


My config:
Deepcool Genome 2
Seasonic 850w
G.Skill RGB 3000 C15  1.35v
I5 8600k not stable at 5ghz (sometimes blue screen & max 2mn with IntelBurnTest)
Vcore offset + 0.070v = 1.392v in A-Tuning
Cpu ratio 50
Cache ratio 46
Level 1

Stress test under Orthos 20mn at 4900 mhz:
At 1.36v (minimum value to be stable) I have some peaks at 1.429v and the proc does not exceed 68°.
In Offset 35 (minimum value to be stable) I have a lot more peaks and it goes up to 1.429v and it goes up to 74°.

On the other hand what is strange is that I am not stable under games with a fixed vcore, even increasing to 1.37v.
And in games with fixed or dynamic vcore there are peaks at 1.440v it's really a lot.


Ps: What's the point of having a forum if no one answers?
