I'm just going off what @LtMatt said back during 7950X3D and 7800X3D release.

Just wait for 9950x3d like i am!!!!!Well that's my mind made up. 9950x3d it is. Dual CCD to replace a dual CCD. Thanks for 'making' me spend more money
It absolutely was a thing, it was well documented inside and outside of AMD. If you go back and look at Gamers Nexus launch review of the 7800X3D, it was mentioned there by AMD as a known issue. However, it did get fixed sometime back (Can't recall exactly but I'll say in the region of 3-6 months back) via a silent OS update. That update meant that you could move between parts and not get a performance penalty, therefore no longer having to reinstall the OS for optimal performance. It's a good thing as it was far from ideal tbf. Sometime back, BIOS options were introduced to allow control over this functionality (forcing workloads to one CCD) in the BIOS, but that always required a system restart so the software solution was preferred, if not a bit more prone to potential issues relating to other software such as the OS/Gamebar/Chipset etc.

That sounds right to my recollection.
There were two sorts of errors as far as I know:
- when moving from 1 CDD to 2 CDDs, the CPU wouldn’t properly park the cores on the second CDD in games causing cross CDD usage and a loss of efficiency.
- when moving from 2 CDDs to 1 CDD, you ended up with half the CDDs on your single CDD being parked (which is what happened to Gamers Nexus as per the vid I posted). Even though they did everything by the book, they still had issues.
Both issues aren’t (or at least weren’t) necessarily fixed by just enabling / disabling the multi-CCD functionality in the BIOS… so if you’re not not doing a fresh windows install, I’d pay close attention to all of your cores to make sure they are doing exactly what you expect.
As said, hopefully now resolved but it was an issue for some time.

@Richdog I assume you have built the new PC with the 9800x3d now?
What did you upgrade from and what are your first impressions?

I think you are right from memory, that there were two types of issue and that the BIOS tweak did not address both.
However, at least now as i understand both should be solved with that OS update.

Do you know if that OS update applies to all versions of Windows or do I have to find a reason to hate myself enough to "upgrade" to Windows 11?I think you are right from memory, that there were two types of issue and that the BIOS tweak did not address both.
However, at least now as i understand both should be solved with that OS update.
Okay so the fix was partial OS update and partial Chipset driver update.
It does not apply to Windows 10 unfortunately, so you would still need to reinstall OS in that scenario. It's time to join us on Windows 11.
Hey mate yup its all running now! I literally just swapped out the motherboard, CPU and RAM for the new stuff and other than needing to re-activate windows it seems to be running fine after reinstalling the drivers!
System seems snappy but I will test some games today to see if I get any noticeable performance increases in VR. I am expecting my minimum framerates and stutter to improve leading to a smoother experience!
Now to see if there's any BIOS tweaks I can do... maybe I can get CL28 running on my RAM!
EDIT - Yup, the windows activation process still makes me want to throw myself out of the nearest window.

Nope
It's well worth upgrading to W11 now, the HDR support alone seals the deal. I wish I had done this earlier.Okay so the fix was partial OS update and partial Chipset driver update.

It actually does run games ever so slightly faster than W10 too. I think it's safe to say the OS has matured enough to be worth making the jump, especially if you couch game, as the support for gaming TVs are much better and more streamlined. Gaming on a 65" 4k120 display with VRR and HDR is heavenly.
Gaming on my HP Reverb is impossible on W11 because they removed WMR. -So I stay on 10.

The onboard VGA is showing as no drivers in windows. Do I download the AMD driver from the manufacturer website? I have an Nvidia card install...

I've had exceptionally bad luck with the 9800X3D.
Two have now died on me after approximately one week's usage. (Identical configuration ran the 7600X fine for 6-7 weeks while awaiting the RMA replacement)
Whether it's a fault with ASRock motherboards specific to the 9800X3D or very bad quality control at AMD remains to be seen.
I see people literally dissecting their processors to inch out a percentage point more performance without a hiccup and here I am with two dead processors after being mortified at even enabling EXPO.

Out of the box what's the all core boost meant to be?
In Cinebench 24 at 100% load CPU all cores is running around 4.94GHz.
