Help lowering Vcore in AsRock B550M Pro4

Hi, greetings..

 

I've been using intel since Lucifer was in heaven.. 😹

This is my very first AMD cpu. Ryzen 5 3600. 😽

 

From past experience (with intel & boards), the "Auto" thing is usually quite high than necesarry.

My goal is, lets say, to go green... long lasted, cool CPU.

 

Is it possible to make peak Vcore lower (say 1.26V) while keeping PBO on?

 

Stressing the CPU using CPU-Z already hit 85°C. I though CPU-z stress-test wasn't too heavy...
Vcore during stress-test is 1.306V (it's on "Auto" mode).

 

• Is it have anything related with load line calibration level? what higher or lower level mean?

 

 

Any help greatly apreciate.
Thank you.

It's thundering now. Literally....
I will turn off the computer and sleep.
I might just be able to read & reply tomorrow.

 

I don't want this new computer to follow its predecessors...
died by lightning (presumably, voltage spike from the mains).

Try it and find out. I doubt it.

Vcore wasn't 1.306V, VID was. VID is the "requested" voltage from the VRM, by the CPU.

 

LLC intentionally overshoots the VID to overcome voltage droops under high current draw. Higher levels increase the effect of this. This allows a more consistent voltage supply to the CPU. (without LLC, the voltage seen is highest at idle, and lowest at full draw. Exact opposite of desired outcome.)

I don't really understand the abbreviations in AMD and their functions.
So, I kept the voltage on Auto, but I increased the fan performance profile. Just slightly better score in CPU-z.

 

I did a video conversion earlier, CPU temperature reached 91°C, geez. This room is not air-conditioned, ambient temperature reaches 30°C. I think the cooler I'm using is too small. I took it from my previous system, a 3-pipe cooler, ID-Cooling 213v2.
I'll probably replace it with the Gamdias Boreas M1-610, a 6-pipe cooler with no gaps, for around $27.5.

I think that would be the best option for me now.

 

thanks svmlegacy
