I agree that 32 GB is too much for average users. A few games now require 12 GB which is an awkward amount, 16 GB should be safe for the time being.
32 GB is useful however for video editing (HD video needs LOTS of space), 3D rendering with large amount of textures and for hosting virtual machines (which has many uses in itself - ie. hosting a different OS for software development).

You're joking, right? :D

Yeah, sure! O_o'
(actually my previous rare-but-happening BSODs disappeared after that)

Yup, unfortunately that can be a thing - RAM sticks not liking a DIMM slot, but working perfectly fine in the other.

Thank you for the videos, ariaspi. Those were informative.

Doesn't look like it to me.

The prices are going down in Denmark.

Glad they were informative. Let us know what RAM you'll end up with.

Will do. Thank you, again.

I was wondering whether I could just put in 20 gigs and see whether that would work or should it always be that the RAM sticks be the same capacity?

16GB in one channel and 4GB in the other?!
Same type and layout (eg 4 dice on a single side and such). It might work with different sizes and layouts but I suspect that is on a minority of motherboards if at all. Everywhere they recommend same amount of RAM in each channel and same kind of memory,manufacturer and layout, even same model. Be warned they can make changes to a model without changing the model number becasue it has the same speed and cooling fin...

You can. Are you thinking to pair a 16 GB stick with a 4 GB one? It would be even better 16GB + 8GB, but you won't have dual channel configuration when pairing different size sticks. And besides that, the risk of running into incompatibilities is not worth it, in my opinion.

First Ryzen generation is notorious for being very sensitive to memory configuration. The second generation and the 400 series motherboards are much improved in this regard (Ryzen APUs are 1st gen, AFAIK).

If you can test different memory sticks before buying them (like knowing someone in a shop), then you can give it a try and test the system with Memtest and similar programs.

Yes, exactly.
I was looking at finding the exact same RAM in the same configuration (speed, model, ect.) except for capacity. Hmm. That sounds concerning.

Yes, exactly. Yes, also correct. Anything, really that gives me some extra memory. On the note of incompatibilities, you are probably right.

I have a 2400G APU. Ryzen 5 2400G to be exact paired with a B350 Asrock mini itx board. I would love to find out whether I'll run into any problems with that.

Knowing someone from a shop would be great but the shops I know, have limited hardware because they are salvage shops.

I think you'll be fine with "only" 16 GB for the next two or three years. This video will probably answer some of your questions.

A recommendation I could give you is to close the programs that you don't need when playing memory demanding games. Look in Task Manager how much memory the programs and games need (enable the Memory - Peak Working Set column). Have less tabs opened in your browsers when you game. And reopen the browsers after longer sessions.

Nowadays every little shitty program wants to have some updater or monitoring thing running all the time. If you use CCleaner, under Tools > Startup you'll find the programs running at startup. Disable what is not essential, like for example that Adobe Reader Speed Launcher, if you have it. I don't use Adobe bloatware, I use Foxit Reader instead. When you see entries/programs that you don't know what they do, just google their name. You'll find plenty of answers and decide if you need it to run all the time or not.
