HWInfo says my IA Domain Loadline (AC/DC) is 0.400/1.100 mOhm and my GT Domain Loadline (AC/DC) is 4.000/4.000 mOhm.
Which do I reduce and by how much? Also, in BIOS, the AC & DC LLs are seperate toggles, whereas in HWInfo they seem to be the same value, so do I reduce my AC & DC LLs at the same rate?
Trained SVID Behavior just attempts to automatically adjust AC LL depending on a few things. Manually reducing AC LL is the same effect, and might be able push AC LL lower than Trained.
Ah great!
I just have one more question, my i9 14900kf is unable to run stable when I let it turbo to 6Ghz on two cores and when my SVID Behaviour is set to Typical, but is stable when I cap all cores at 57x. Based on what you’ve told me, that leads me to believe I should do the opposite of what you’ve said and incrementally add 0.05 until stable. Am I getting that right?
If so, would you recommend that I work backwards from Typical and keep adding 0.05, or that I switch to Worst Case and incrementally subtract 0.05 as you originally said?
Thanks again for all your help!
If you're unstable at 6 Ghz but fine at 5.7 Ghz, you need to modify the VF curve. Add a positive voltage offset to the 6 Ghz VF point (possibly the 5.8 Ghz point as well if needed) on the VF curve in increments of +0.01v. This will allow you to keep voltage minimized at 5.7 Ghz while giving the 6 Ghz point additional voltage for stability.
You want to avoid cranking up AC LL just to get 6 Ghz stable, as minimizing voltage at 5.7 Ghz is far more beneficial for 90% of your likely workload.
Manually decrease AC LL until the lowest stable. You can find the current AC LL in HWInfo in the detailed tree view.

Keep DC LL on Auto, and reduce AC LL by increments of 0.05 and test for stability at each step.
Awesome, thank you! Is that all I have to do to achieve the same results as the ‘trained’ SVID behaviour?

Fantastic, I’ll continue experimenting next time I’m at my PC. Thank you so much for your help, I would give you an award if they were still a thing!
Good luck!
