Question PBO setting for Ryzen 3800x processor

[candasulas]

Hello,

There are a few things I am curious about with my Ryzen 3800X processor.
I want to learn from friends who have knowledge.

I have an Asus Crosshair VIII motherboard and Asus Strix LC360 AIO liquid cooling.
I want to increase the processor performance a little more.



But in my research on the internet, it says that manual overclocking should not be done for the Ryzen 3000 series.
I've seen reviews and articles stating that processors are built on the principle of operation at variable voltage loads.
Many places say it's not good to give constant voltage.

All my settings are kept at factory settings. My CPB setting is in auto.
I also use my PBO setting as Auto. There is a setting between 1x and 10x in the PBO. (Scala)
Is it better to increase this setting or use it as auto tuning?

My aim is to use the processor with optimum performance without damaging or degrade it.
I would appreciate it if you could give information about how PBO and Scalar settings should be.

Simply do not use PBO. Too much power increase and by far too small performance benefit.

My 3800X was solid at IF 1900
I ignored any XMP profiles. ( set DDR to 3800 )
Used Dram Calc to get some numbers to tweak DDR.
( Be sure to read about LLC mode for your MB - not all other suggested parameters worked for me - you test )

Anyway .. check my older posts ...
Your performance gains will be in bandwidth and latency.

Your results depend on the quality of the DDR and the CPU now

I use it with PBO turned off.

I cannot overclock my ram. Because I use 4 kits. I have a total of 64gb of ram. Overclocking when using 4 kits can make it more unstable.

I just want to lower the CPU temperature. Therefore, I wanted to find out if it is risky to give a constant voltage.

Are you air or water cooling your CPU?
