I9 13900k undervolting adventure

[Vatergascoigne]

Good morning everyone, I have a few questions about undervolting an i9 13900k. Of course there are tons of tutorials and videos online, but I haven't really gotten a clear idea from them. The whole thing is supposed to take place on a Rog Strix Z790-F Gaming Wifi. What I noticed is that UV is often operated in two places. Either with a negative offset for the actual VRM core voltage or global core SVID voltage, and then adaptive mode also with a negative offset. What I would now be interested in and for which I have not found a concrete answer is how these two methods differ and which is more effective for the project, or what are the advantages and disadvantages.

Hello, @Vatergascoigne 

May I ask if you have encountered any anomalies in your daily usage?
What is the current BIOS version, and did the issue of insufficient CPU voltage occur under default BIOS settings?
Have you attempted cross-testing with another CPU or considered updating the BIOS version?

Thank you.
