The Vdroop on the core is pretty high on y-cruncher. Max voltage is 1.406V but running at 1.325 - 1.34V. LLC is set to Auto.
SOC voltage is very stable at 1.05V and RAM ranges from 1.35 to 1.39 but generally runs at 1.37V.
The highest temp I saw was 66C. I don't see VRM temps anywhere in HWinfo. Maybe I'll try pushing it higher if it clears a few more passes of y-cruncher.
Yea, there is a substantial amount of vdroop at load; even at LLC 2 I get 69mv but I think your vcore is likely fine for 3.8. If you havent done anything wild on the RAM side, .950 is likely fine there as well.

Haven't tried SOC over 0.9 yet though. Does it help on cpu overclock too and not just memory overclock?
CPu loadline calibration have no impact on cpu overclock right? Just to keep the vcore drop in check?
I have a feeling i am missing something obvious though.
LLC compensates for the vdroop, yes. It can help with an overclock as well; if you're at 1.45 vcore (hypothetical) and didnt want to go any higher, you could use LLC to counter the vdroop (and should in this case in my opinion). At 3.8, 1.35 should be enough under load for the vast majority of CPUs (likely somewhere around 1.42 in BIOS with LLC 2). As posted above, somewhere around .950 on the SOC seems to work well for me.
