12/24/48/whatever GB RAM sticks. Is there any catch?

[Macro Device]

Not so long ago, many manufacturers introduced DDR5 sticks of peculiar capacity. Is there literally anything I should pay attention to other than what I'd've paid attention to anyway, such as clocks, timings, $ per GB?

I assume the only stuff stopping me from outright using it might be an outdated BIOS version. Which is too easy to fix to even care about it.

I might be totally wrong. Am I?

More context: thinking about getting a B650 + Ryzen 9600X combo with a couple 24 GB sticks to call it "I'm prolly never gonna run out of RAM again."

No catch. It's all about making more offerings for more sales. Mr. Crabs runs the show....

12GB isn't exist in PC components. In this moment I see offer in one shop for kit of 2*48GB DDR5 5200(G.SKILL Ripjaws S5 and also Flare X5) which is little cheaper than 4*24GB. Not sure for the prices in Russia.

SO-DIMMs do exist.

I'm not doing 4x24, nor am I doing 2x48. I frankly don't even need more than sixteen. I just don't like upgrading very often so I'm planning on a double overkill RAM kit so it serves me well until it becomes Ivy Bridge obsolete.

Rank?

Rank?

Name's Shitposting. General Shitposting.

Jokes aside, the number of ranks doesn't really matter for what I'm doing (web browsing, movie watching, occasional photo editing, occasional gaming). I get single, I OC it harder. I get double, I just enjoy it. Whatever.

There are lpddrx for mobile phones and tablets with this capacity(12GB). That's all. Where did you see so-dimm 12GB modules?

I'm wondering if Intel's and AMD's memory controllers can handle weird combinations of sticks, such as 16+24+32+48 GB. Right now it's just curiosity but in a few years, when people start reusing their old components for new purposes, and try to use whatever is found in the drawers, good compatibility with mixed sets might have some practical value.

It has already been answered in other topics. But here it is in short. Yes, and this is not limited to computers. But when combining with different volumes and frequencies, the volume and frequency of the module with lower characteristics is automatically used. So, when combining 16+24GB, for the sake of simplicity and explanation with equal frequencies, 16+16GB will work in a dual-channel configuration, and 8GB (out of 24GB), which are more in one module, will work in single-channel. This is not 100% guaranteed!
Ps. Memory modules must be from one generation. DDR2+DDR3 or other combinations didn't work together even on motherboards which have slots for this two generations

I have 2x 24 GB in my Zen 4 system. It works just like 2x 16 would.
