Gigabyte Aorus Elite 3900X, peak core voltage setting in BIOS

Currently on my Ryzen 9 3900X I have a small under-volt using Dynamic Vcore, my computer is not overclocked. I installed Ryzen Master and was surprised to see peak voltage sometimes go above 1.4v. Inside Ryzen Master I set peak core voltage to 1.25, and everything appeased to be running fine at the reduced power peak voltage.

Here is the question. How do you set peak voltage control in the BIOS, so I don't have to keep reloading Ryzen Master and setting this.
 
I normally only use BIOS settings, however when I installed Ryzen Master was surprised to see voltage occasionally spike above 1.4v.

At the moment I have a Vcore offset reduction in BIOS (can't remember what is it without rebooting). If running stock is a reduction in Vcore offset the only thing worth changing on my system?

EDIT just noticed you have the same CPU & Motherboard as myself.

More questions. What software are you using for that screen shot above? Also what BIOS settings are you using?

Brizzles,

I've just gone into BIOS, I was already running an offset of -0.078v on the Vcore, however my Vcore SOC was default, and set this now to 1.052v. I've left Vcore offset at -0.078v for now, however if I'm stable with new Vcore SOC, will reduce Vcore offset lower. I agree I don't want fixed Vcore.

My memory voltage is 1.2v, but I'm 2666 ECC memory at stock speed, and happy to keep memory at stock.

Just to confirm there is nothing else really worth doing if running stock, and other then monitoring I don't need Ryzen Master any more?

Thanks for your help.
 
Yes thanks again, will leave Ryzen master then.

I'm aware that all CPU's vary, but was using yours as a guide. Will make small adjustments to my settings over time, just see what's stable.
