192gb DDR5 On AM5 7950X3d

Officially 7950X3D only officially supports 128GB, unlike the Intel chips e.g. 14900K that have support for 192GB.

Whilst 4x48GB Dimms may work, it's unsupported territory.

Why do you need so much RAM?
You’d need to look at Ryzen Threadripper for that sort of amount of RAM.
I doubt the Intel memory manager in their CPUs is good enough to support 192gigs, even at very slow JDEC speeds.
I never watched this, but you might find it informative (or not):
AMD Ryzen 7000: 48GB DIMMs, Agesa 1.0.0.7 And A Future With 192GB RAM
48gb DIMMs are here, but things aren't quite so simple for Team Red. Wendell lays it out here!Forum thread: https://forum.level1techs.com/t/ddr5-4-dimms-on-a...

MSI claim you can do 5200 with a 13th gen CPU and 4800 with a 12th gen CPU and their Z790/Z690 Carbon, but these are only task manager screenshots

I’m sure MSI didn’t bin CPUs until they got to a golden sample that can run all that memory.

Seriously. Don’t try run huge amounts of RAM with consumer grade electronics.

I can't find it now but I saw on an Intel document the claim of 192GB @ 5200MHz on 14th gen, similarly some high end Z790 boards claim 192GB @ 5xxxMHz (EDIT: Since I last checked at least one of those has changed to 128GB @ 4800MHz).
But as above if you actually need that kind of RAM amounts you are best moving off consumer grade hardware.

If you're not prepared to mess with it manually, I'd strongly advise you don't buy 192GB (which like..., 2 people are using and they both work for MSI).

It won’t just work. XMP is technically overclocking and not within the JDEC standard.
You’re asking for a miracle.
You can still game on a Prosumer product like the Ryzen Thread ripper.
It’ll just not be as fast as a 14900K as it has slower cores and More “nodes” (can’t remember the technical term right at this moment) which add latency.

Lordy, ThreadRipper Pro can support up to 2 Tib of memory at 3200 MT/s.
That’s insane.

I actually have just finished testing 192Gb(4x48Gb) of DDR5 5200Mhz (Corsair CMK192GX5M4B5200C38(Ver 3.53.02 - Has to have SN Starting with above 2311 on the first 4 digits) but with a standard Ryzen 9 7950X and it worked surprisingly well. I didnt have an issue at all which i often do with 4x32Gb. This was in an Asus Proart X670E Creator Wifi motherboard and that memory is on the QVL. I have also found that the same memory will work in the X670-P Wifi so that is next to test.
Soldato
This is a key factor - getting hardware that has been tested and is supported.
I'd contact Overclockers directly and see if they have that RAM and motherboard and CPU.
AMDs memory controller is stronger than Intel's but they don't run high speed RAM due to the Infinity Fabric.
For key work, I'd still fall on the side of safety and buy a prosumer solution like ThreadRipper pro but it's great that Asus have tested and support that amount of RAM on that motherboard.
I wonder if it would work with the 7950x3d? did you have to do any manual tweaking to get it stable?
Soldato
I cant see why it would be any different with the X3D to be honest, it actually is slower for productivity than the non X counterpart.
Nope, banged it in, set to DOCP (The specific corsair modules that have been tested by Asus are the XMP Version not the EXPO/AMD Optimised version as there isn't currently a 192Gb Kit for AMD). What is strange is that in the past Asus wouldn't qualify 4x modules and said it would only run at the "Auto" setting.

I like boards like the Creator, they're a good halfway between HEDT and regular boards, though they do have a price tag to match and whether Asus actually test them more (for workstation use), I don't know.
There seems to be a death of stuff in that halfway space though I can see why Intel and AMD segment the market the way they have to avoid businesses, etc. buying cheaper consumer products over the full HEDT or server offerings. I miss there not being a proper X79 equivalent in this day and age where you can pay a moderate premium to get some advanced features/more PCIe lanes without the huge cost and additional complications of going for a full server type setup.
