I have never tried to under/overvolt a CPU before, and are therefore looking for some support with the i5-14600KF CPU

Looking to slightly undervolt it to achieve lower temp./noise and to give it a longer life

BIOS is updated to newest version, and the only thing which is changed from default settings are the XMP for the memory

What should I change to undervolt the CPU slightly?

Hello and welcome to the MSI forum.

The settings you should look at first when trying to undervolt your CPU are actually found on another screen than what you posted. I can highly recommend this guide to get you started. Over one hundred thousand people have visited this guide. Even Kings and Queens and the Pope himself have found it easy to follow. Hopefully, you will, too.

 
High praise from royalty and religion (although i don't care about them too much, i'm here to help the common people). I would like to add one remark though, which i also mention in the guide: With a B-series motherboard, it can sometimes lead to drastically lower performance once you lower "CPU Lite Load" below a certain point (somewhere around Mode 10 and below). This "CPU Lite Load" mode is the go-to easy undervolting method, it's under "Advanced CPU Configuration" which the OP failed to include a screenshot of (but i show it in my thread). But on B-series boards it can happen that a feature "IA CEP Support" will needlessly intervene and bring performance to a crawl, because it thinks something "outside of the norm" is happening. And there, you can't necessarily prevent this, unlike on a Z-series board.

So while you can still go by the guide to some extent (i'd certainly try Mode 10, 9, 8 or so, and watch performance closely via Cinebench score results), you might not be able to exploit the full undervolting potential your CPU would normally have. And this also would extend to other methods of undervolting, like an Adaptive + Offset undervolt. So if you see this drastic performance decrease after a certain amount of undervolting, don't bother testing other methods than lowering "CPU Lite Load", they won't work either, if you can't prevent "IA CEP Support" from intervening.
