Question AMD TRX40 MB 512GB memory support (64GB x8)

[Shteud]

Hello everyone!

Not sure does this right place for this question.
I plan a workstation build on AMD 3990x with some OC of CPU, so I plan to use TRX40 MB.
But i need to use more than 256GB ram, what most boards have supported (at least that manufacturers say).
There is 64GB ECC RAM modules on market (for exp. KSM32RD4/64MER from Kingstone) so theoretically with 8 ram slots on MB i can achieve 512GB.
But I can't find any info which approves this theory. So maybe someone has any info on this topic?
Or only way with more RAM is using SP3 socket motherboard and 8 channel memory controller?
But if I do so, can i install 3990x there and OC it?
Be grateful for any useful info guys

I can't find anything other than the limitation of 256GB: https://pcpartpicker.com/products/motherboard/#s=38

Yes, I read the specs of boards. But maybe it's an undocumented feature
3990x support up to 1TB ram.
and there are 64GB RAM modules (so 8x64=512) and maybe someone tried by themself.
