Core: 4.5GHz (non-AVX - same as before - it will do 4.6 and 4.7 at higher Vcore, but not at 24/7 power/temp levels AFAIC)
Cache: 3.1 (previously 3.0 - even 1.15v would not allow > 3.0GHz)
VCORE: 1.16v (previously required 1.175v)
VCACHE: 1.10v (previously 1.05v for 3.0 --- > 3.0 was not stable)
LunaP in particular - you have ludicrously low VCORE (1.10-1.12v last I heard). Can I ask what your VCCIN is these days?
The bump from 3.1GHz mesh/cache is nice... That's become such a choke point that even 100MHz shows up quickly in real and synthetic numbers.
It was 1.112v for vcore, but I've bumped it to 1.115 just in case for stability given my ram timings/clock, since 1.37v now on RAM @ 15-15-15-35 and 300 tRFC and 32 tfaw
I did manage to get 3.2 on mesh around 1.19 I haven't messed around w/ it too much since though since I got busy with other stuff, ended up trying to update my display rig, grabbed a 43" LG then calibrated that for a few days, then ended up getting a q7f 55" tv and made that my main monitor, (Display cal takes days I swear since theres so much fine tuning...) now building up 32" monitors around it and setting my art studio back up, might have to get a desk thats slightly 6-12 inches wider than mine since hte TV takes up the full width = monitor bars for the monitor arms are kinda blocking a bit of the view so can't angle the monitors out perfectly unless I move the TV back. Can't seem to find a stand alone option to just put on the floor near em.
Back on topic...
I'm def curious on the vdroop, as iirc I'm at lvl 5 and was tempted on 6 ( will have to recheck ) I was trying for a bit to push avx but 4.2ghz for avx2 seems to be the safe area since at most I'll hit high 70's, at 4.3 I can dip into the upper 80's its a huge spike. Though if other things like vdroop and vccin could help that I'm all down for it as I wanna get to tweaking more, especially since its winter. Any tips or things to test lemme know.
VCCIN atm is sitting at 1.81
Gonna try some actual render sessions w/ some speed paints and OBS to verify just how much vs benching/stressing they utilize in comparison as I'm hoping to possibly bump avx further.
Would be GREAT if there was a utility like Process lasso that'd upclock/downclock ur AVX based upon programs you're running.

Looking like LLC6 vs LLC5 might have the same effect with VCCIN @ 1.85v.
So, that suggests the ultimate issue for me is droop.
EDIT2: eventual miscompare, but better than the MCEs I used to get... so maybe 1.87v? trying now
Which would you recommend, higher or lower droop for these?

At 4.5 three of the cores are over 100c so that's about the limit of a non-delidded chip. Though two of the cores are still at 70c so it's very inconsistent. And this is with 26c water through the block, lol. Also managed to pull 665W from the wall.
I did manage to hit 4467 in cinebench though. With some mesh/memory tweaking I should hit 1 point per mhz. Single core score is 202, faster than an 8700K at the stock 4.7 boost
Any settings that would help lower vcore? Gonna try setting the vccin to 1.9v.
If you're getting some cores over 100, I'd def look into clocking per core as some may not require as much voltage as others, but also gotta remember TJ etc since closest, its a game of patience. Though I'm sure people have already answewred by now as I'm still catching up on the last 5+ days worth of chat.
