I remember a video by BZ where he went through all the BIOS settings in the gigabyte X470 board and I think he said the max offset the board allowed was 300, I think that was mv but I'm not sure. I have it bookmarked downstairs though.
At some point I'd like to run through an offset with you so that I understand what is required, if that's ok with you?
It's your thread - you don't have to ask

Perhaps -0.3V is what he meant by the maximum offset allowed? In any case, that's too much of an offset, either way - positive or negative. If you set that much of an offset, performance will drop for sure, and it may be unstable. You shouldn't have to go past -0.1V. As a general rule, start from 0, work your way down in the increments it allows (I think it's like 0.0075V steps or something that small), and make sure that it's actually changing your Vcore (I think some of the values are somewhat redundant, they result in the same Vcore as the setting just above or below them, like -0.06875 and -0.075 are the same). Find a spot that's a good balance between performance/heat/noise. For me, -0.05V is good, but -0.075V is actually still where I bench highest on CB. A lot of boards will feed too much Vcore stock on Auto voltage, which seems to be detrimental as it generates too much heat, and hurts performance by hitting the limiter all the time.
I think I figured out -0.075V was stable through a couple of hours of P95 Smallest back in September or so, and just kept at it all this time. I think -0.08V started logging WHEA errors in HWInfo (WHEA errors kinda like a friendly "hey, I think this will run into problems down the road" reminder for me, followed up in order of severity by P95 crashing, OCCT crashing, BSODs, graphical artifacting, and finally failed boot), so I stayed at -0.075V.
The Core Voltage field and offset setting seems to be really janky; Auto setting is default and doesn't allow you to set offset as it's greyed out. If you change Voltage to Normal, you can then set an offset. You can change it back to Auto if ever you wish to go back to stock Vcore, however, the offset doesn't go away, it somehow stays even if you're back on Auto (and you can't change or remove the offset on Auto, it's greyed out even though it's there). Like, if you run the system on Auto again but didn't manually reset the offset to 0, boot into Windows with it on Auto voltage and it'll still act like it's offset. So if you ever want to change the Vcore offset back, you have to be in Normal mode first, remove it, then switch to Auto mode, and you'll be back on stock Vcore.
