RAM for AMD Ryzen 9 5950x: 2 vs 4 for FEA

[KyleGranger]

TL;DR

Is it better to use 2 sticks or 4 of RAM to achieve the same total memory

I am looking to build a computer using the AMD Ryzen 9 5950x. I am wondering I will be better off with 2 or 4 sticks of RAM. I will be using this for FEA.

If my search went right, it's limited to two memory channels anyway. So two or four stick - there should be no noticeable difference.
On the other hand, with two stick you will have free upgrade option for the future (I guess the usual motherboards has four slots).

Yeah I think you're right about two channels. What do you mean by having a free upgrade option in the future?

If you have two sticks in a four slot motherboard, then more memory is just buying two more sticks.
With all slots full, it's far more fuss.

O ok I see. I'm planning to max out the memory at 128 GB so I'm trying to figure out if I should go 2x64 or 4x32. It looks like there are far less options for 64 GB sticks though.

But if you get 2 x 64gb for 128gb then you have room to further expand to 256gb in the future.

What kind of home computer software needs that kind of memory? Some kind of game? Massive data manipulation?

The CPU and motherboard max out at 128GB so I think I'll be running this amount for a while.

I'm running Ansys and Comsol. With multiple simulations, it's pretty taxing.
