Whopping score that Matt, massively strong IMC on that sample you got.PBO + -40 All Core CO.

Someone asked for Aida, here it is.
Keep in mind latest BIOS added +7/8ns or so onto Aida latency.

Thats a looooong wait
See you in 2027 probably, and it would probably be on AM6 as well with DDR6.
Thinking about it that does seem like a big jump, if you can wait it out!

@LtMatt doing eclk at the end when everything else is maxed out?
Caporegime
Yes Robert. Never really experimented with it before so will be something new for me. I also want to try out an all core overclock with manual voltage to see if that can bring any additional gains. With PBO and CO, not really seeing any higher than 5.4Ghz, with a 5.425Ghz peak clock.

Yeah that's the peak you'll get no matter what. Only way past is eclk. A lot of crew shifted over from intel to amd and everyone's maxing out around that. So far, no one saw much gain from all core but be interesting to get your experience. I'm in batch no 3 from ocuk so it'll be a while before i can join the party.

Useful info, thank you. Eclk it is then i guess. However, I just heard that there is a performance bug once you go past 100.50 eclk, not sure how true that is. Will find out soon enough i guess.

I should clarify that yes with an all core, you can get past 54x with an amazing bin. Just no one found the value in doing that (so far). Still early days ofcourse. It's finally nice to have x3d you can tune 
AMD are hard binning for 9950X3D atm, the early batches of 9800X3D's won't be stellar as we are seeing.
Matt got lucky though with a super strong IMC on his sample.

Yeah, I tried CD23 at 1.35v and 5500 and instant fail. Looks like that was way too ambitious.I should clarify that yes with an all core, you can get past 54x with an amazing bin.

I did, I just wish my cores were a bit stronger.
Got another sample coming Monday, I hope for a similar IMC and stronger cores. Probably unlikely but who knows.
I'll be selling one of them probably in a few days.

Ofcourse but that’ll be an expensive part for maybe 200mhz max boost. Save that money towards a 5090! Unless Jensen won’t be kind.
AFAIK neither amd or intel do imc binning so its pure lottery and yes Matt won it!

Zen6 with 16/32 cores on socket AM5 (with DDR5 6400) could work by simply putting X3D on everything.
The problem the two CCD SKU's have is they're becoming bandwidth starved, X3D solves this problem.
Only problem AMD would face is that they wouldn't have the cachet of being able to sell uber "X3D" SKU's...

Will be interesting to see if they use X3D on both CCXs.
I think this is pretty much a given

Lordy that would be interesting. I guess the tiny generational uplift from Zen 5, and the removal of clock speed neutering from the 3D die design makes it very likely.

It's clear they are doing some very aggressive binning with how bad some 9800X3D samples are.

I wouldn't be surprised if the new CPUs have dual CCDs with 3D cache. The reason they didn't do it with the Zen 4 dual CCDs was the cache limited frequency substantially so they kept an normal core for the high frequency workloads to minimise the performance hit. Now there's no frequency benefit from not having 3D cache it is feasible to put cache on both without a performance loss.
Might be cheaper to stick with one CCD with cache though.
