Asus ROG STRIX memory upgrade

[SJX]

So, after waiting months, I finally got this one from here.

 

It only has 16 GB of RAM, but I need 64 gigs. (not for gaming of course, but for some machine learning workloads).

 

Can someone guide me on the following please:

1. best "32 x 1" memory module for this laptop (for this AMD cpu)
2. a video (or two) demonstrating how to replace RAM as I have not changed RAM on a laptop before
3. any AMD specific config that I should tinker with (although if it's not super important, I'd want to avoid it)
4. anything else I should be mindful of when doing this surgery
