So I think I figured out what the issue I'm having is.

I installed a bunch of 140mm fans and redid the paste on the CPU with Arctic Silver. This made no difference CPU wise, though my GPU is a lot happier.

When I got my system from OC UK one of the screws for the 150i does not sit flush, it's at a slight angle, so the cooler is not making full contact with the die. When I reseated the cooler I had the exact same issue as when it shipped. Full load temps at stock are about 60C, PBO is just flat out impossible to run and crashes.

Don't think there's any issue with the backplate so it looks like a defective cooler.

Definitely explains why my temps are sky high compared to others even with the same cooler.
 
Update

Been messing around with motherboard voltages tonight.
5950x
5ghz (single core)
4.5ghz (multi core)

For some reason my Multi core score is much lower than my previous best so will need to try & figure out why.
Plus side, temps much lower now, ST temps 60c, MT 70c

What settings do you have under pbo? Nice results

Fmax-disable
PBO- Auto

Max Boost- 175mhz
Therm. Limit- 110c

Advance Menu
PBO- Advance
PBO Limit- Motherboard
Scalar- 10x
Max Boost- 175mhz
Temp- 110c

I have my curve set to my CPUs cores so that part will be figuring out your strong and weak cores.
What I did was set my Max boost to have cores hit 5.150ghz set curve to -10 on every core then ran a boost tester program to put very light load on each core... watched to see if they hit 5.150ghz. If not then I drop curve on that core by -5... test, repeat. Found I have two weak cores (5.100 and 5.125ghz) those I drop to -30 and -25. others are between -10 and -15. Every CPU is different so it will vary.

Getting an anomalous result in Cinebench R23 on a Corei7-4500 laptop running Win 10 Pro
CPU Multi Core: 2504043 !!
CPU Single Core: 391
Any ideas what is going on here?
 
CB23 Single and Multi
5900X Stock +PBO 200MHZ
32GB 3600 C16 Ram
Single 1645
Multi 21810

Need to tune Ram and CPU, hopefully can get a bit higher.

After a day of tweaking I think I can claim a crown as highest 3900X Multicore with 19566

3900X @4.3 all core, ram 3200 CAS16

You wanna be lowering voltage on the stronger cores not the weaker ones.

Jury is still out on this. AMD official slides guide to START with strong cores.
For me I find there is much more curve headroom on weaker cores. Right now at -5 on two strong cores, -15 on next 4, -20 on last 2
Presumably weak core curve has been nerfed more from factory.

Ah right ok, hopefully RM update soon with curve, be easier to work out then.
 
Can someone explain this strong/weak core business? Are "all chips made differently" so to speak and some have cores that don't perform as well as others? Hence, beyond other system specs, varying benchmarks?

I've built 3 identical 5950X rigs (literally identical, down to cases and fans) and I'm getting Cinebench multi scores that range from 28,170 to 29,193.
 
not really messed about with my 5900x much, this is with pbo on.

@humbug sorry forgot to say please add me to the list please, first time scores..
