    Go to Bios>Extreme Tweaker menu then scroll down to SOC.
    Be careful with SOC voltage as excessive voltage can kill the IMC on your chip.

    Hello,

    Values of up to 1.15v are fine, exceeding this should not be necessary on majority of CPU.

    Doesn't let me change to a value.

    How to set SOC Voltage.

    Enter BIOS, Advanced mode.

    Navigate to
    Extreme Tweaker (maybe AI Tweaker) -> CPU SOC Voltage set to manual
    -VDDSOC Voltage Override and type in the voltage. 1.05 (2xdimms) or 1.1 (4xdimms) or 1.15 (4xdimms, not quite stable @ 1.1v)

    Care to explain what this even means. The ballpark of excessive, that is ?

    SOC (System on Chip) voltage is what drives all of the System on Chip devices, such as the I/O controller, Memory controller, etc. When you are overclocking you should set SOC to 1.1v, and you can increase that voltage up to 1.2v or 1.25v depending on who you listen too (AMD has not released any guidance around max SOC voltage).

    I actually asked about your thoughts on excessive SOC Values and what that even means.

    I wonder if at the bottom which tell me usable ranges for the voltage I'm setting is all for fun and I wonder if the white, yellow and red colour scheme in BIOS for when I set voltages might be a rough guide to excessive or is that all just eye candy ?

    I wanted to know what you thought excessive means in SOC values since you didn't say and still have not.

    Is this a demand?

    Hmm Not sure exactly what your fishing for RedSector?

    All I know is I diminished a CPU by trying exactly what we're talking about, by raising SOC to 1.32v to try and get stability and although it worked for a while my Overclock would suddenly no longer reach the Target frequency. I set Bios back to default and found I could no longer achieve what Overclock I had before. I tried a previous save profile and again no luck. Hence my warning!!
    BTW: The IMC (Integrated Memory Controller) is what was effected here.

    I tried to research for AMD's max voltage recommendation to no avail and yes i don't think the colour scheme is just for eye candy.

    Hope this helps clarify your confusion

    No was asking to understand your point specifically, don't take as me picking a fight with you, just wanted to understand where you are coming from and what you seen as excessive without the other stuff.

    What CPU was that?

    Well I hope you understand now and without what other stuff? LOL.

    It was my original 1800X and I was chasing a Max Overclock.

    And yes I misunderstood you LOL, You fight you loose
