I need to upgrade to 64gb ram, currently running 7800x3d and Corsair cas30 16x2 sticks.

Unfortunately due to using msfs2024 it blows pass that on occasions and if is under we taking about using in around 30gb, open some external programs couple of tabs and it goes easily pass that.

Plan is to get 99xx3d chip in future so what would you advice? Sell my current ddr5 and just buy 2x32gb? Or will the 99xx3d be able to handle 4 sticks for example? Asking so I don't make expensive mistake
 
Generally memory controllers are happier running with just 2 sticks.

You can get 64Gb RAM with 6000MT/s and a CL of 30; but it's probably worth checking where the sweet spot has moved to on the 99xx3d's. I read 6400MT/s (so presumably CL32) but not paid enough attention post release as I am trying to suppress that upgrade itch for a bit :cry:

They're definitely handling it better running 4 sticks than AM5 did on launch, but I'd still recommend 2x32 or 2x48 as less likely to be problematic.
 
I think I will go with 2x32 CAS30 6000mt/s from Corsair, I know the 32gb version kit works fine with this cpu and mobo, 99xx3d is not out so will be a while before get some more info regards ram, I don't think I will notice that much difference between 6000v6400 but I could be wrong
 
No idea on the 6000 vs 6400 but I suspect you are looking at the same RAM I have and it has run perfectly with and without EXPO on my 7800X3D from the offsso should be fine with the whole 9000 series :)

In TPU's memory scaling article for Zen 5 the difference is very small and the X3D CPUs are even less sensitive to memory frequency, so it is definitely not a must-have.

6000 is pretty much assumed to work @ 1:1 on the majority of memory controllers (2x sticks) and it is likely it will work at 6400 on most 9000 CPUs, but there's no 100% guarantee so the safest option is 6000. If you're happy to change some settings manually you can make it work if you buy a frequency that isn't stable.
