14900k and 4 ddr5 sticks instability? (also max ram still 128gb?) (alien.top)

Been reading a bit, it seems that even 64gb is troublesome\unstable on this platform (also goes for AMD?)

I'd like to go higher than that in my next 3D\creator oriented build, 128 or even higher if possible (been seeing some BIOS updates that allegedly allow up to 196 or even 256gb on some boards?) so I can avoid threadripper build cost.

Is it a real issue and how would you go about building a max RAM-loaded workstation in 2023\2024?

Currently rocking ancient i7-5820k with 64gb ram and it feels a bit tight on the ram side when doing Houdini simulations and even some renders.

What is your use case? Do you need the single core that the 13900k has or will OG threadripper handle you just fine? Do you need PCIe lanes? I've gotten stable results on 4x 48 gb sticks on AM5 but it's been at 5200 speeds with the higher end ASRock boards.

Are you on current BIOS versions? I am on ASUS but have not seen many good reports on 192GB speeds recently. I just got 2x48GB sticks and have them running well at 6200cl32 but might consider getting 2 more if 5200 is a decent possibility.

I need both single-threaded performance but also as many cores as I can get. So 14900 is my best choice I think without breaking the bank with threadripper platform.
