Question Help with Undervolting

[E_KAN87]

Hello,

So I have a 13900K with ASUS z790-E motherboard. I wanted to undervolt through BIOS. I did a couple of tests with Intel XTU and have an offset in mind.

I went into my BIOS and selected Offset Mode and entered a value under CPU Core Voltage Offset. Now, is that all I need to do to undervolt through BIOS? I haven’t saved this setting yet, just wanted to be sure. In the attached screenshot you can see what I have done. Online there are guides where I need to set the same value to CPU Cache but I don’t have CPU Cache, just CPU Core. I am a little lost.

My BIOS Settings

negative values are undervolt

negative values are undervolt

His screenshot shows the negative sign beside where it says Offset Mode Sign. Many Asus boards show the negative sign separately like this. All is good.

-0.00500 V is not going to be make any significant difference. Move the decimal point over a notch. I would start testing for stability at -0.050 V.
