Set PBO on 2950X throughBIOS

Hi,

I'd like to set custom PBO values similar what I can do in Ryzen Master. I found the PBO settings in the BIOS and using Enabled work with some default presets. Now setting this to Manual, where values can be entered does nothing, unless I also set PBO scale.

Now for the "scale" settings I don't know what value to use. This is not something that exist in Ryzen Master and I am a bit confused what is it for and what values are to be entered there. Setting it to 300 seems to work fine, but I am afraid that the voltage may go up too high.

Any general guidance how to properly set PBO on Zenith Extreme?

Increased scalar value relaxes voltage limiting rules of FIT monitoring. You may find reading the section under heading "Where is the limit?" in this post by The Stilt helpful.

The value goes upto 10x on X470, what is the maximum value you can enter in the box on X399?
