[SOLVED] Loss of performance due to asymmetric amount of RAM?

[_Mushin_]

Hi,

I have ordered a Thinkpad AMD Gen1 with Ryzen 7 pro 4750U and 48GB (16GB soldered +32GB SoDIMM) of DDR4 3200MHz RAM.
I am still waiting for it to be delivered.

I have done a bit of reading in the meantime, and I can't help but feel like I've made a mistake, and I should've ordered 32GB (16GB soldered +32GB SoDIMM) instead.
For what I could gather, 32GB would still run in dual channel, and 16GB in single channel, but there would be either a loss of performance compared to a more balanced setup, or not a significant improvement for the extra 16GB.

Can someone more knowledgeable than me, share their findings on the subject?

I plan to use my computer, mainly for CAD design (AutoCAD, Revit, CATIA) an a little bit of programming: C, Python.

Thanks

Depends how much memory you use. If you exceed 32GB of memory, having the extra memory is still better than not having it. Having it drop down in bandwidth may slow down some things, but the memory management should take care of putting higher priority data on the sticks in dual channel mode.
