memory

 two slots, one slot (the other is soldered.) or, 4 slots.
The amount of misinformation I would need to cut paste is ridiculous...

maximum ram is typically higher...I sense boilerplate salesmanship
(more ram, more money)

Sure, it could be their wording,
"two" (empty available) "slots"

Not everyone can be right.
Max 64 GB, Max 32GB.
5600, 5200, cas 46, cas 42

And I don't know why, but Amazon keeps warning me that people want more money than the RAM is worth.
The limitations of RAM could possibly be whatever cheapo memory controller they are using;
regardless, "32GB" sounds ok.

(possibly 64 and the OEM is playing it safe)

Speak confidently on Reddit and Google AI will quote you.

I don't know if this is a bad thing yet.

The point of confusion now is, are my 16GB all soldered in?
Fine, I say, 2x8 soldered.
Or maybe, 4 slots, two filled.
I seriously need to take this apart and hunt down the memory (no one apparently knows where or what it is)
But *I* have determined, it's 2-channel ddr5-5200-cas-42.

Or (more likely)

It's 5600 per the spec, being run at 5200,

and "CAS 46" being run (at 5200) at "42"
But that doesn't mean much, one-SODIMM upgrade or a kit-upgrade?
Does the CPU and the other memory prefer a brand?
(I swear I had a ram number a few days ago)

Speed is there and type, but no one online could tell me if I would need to buy a pair.

If I only have one-something (chip or dimm) installed, fine but if I already use two, I'd need two more.

2gx8 refers to (ideally) a dimm with 8 2-Gig chips. (All this is educated guessing)

so...um...one single 16gb dimm sounds nice, unless I open it and find TWO dimms, 8G each.

and two empty slots, which would mean another 2 8-gig sodimms.

I refuse to capitalize their acronyms, this would look like some hostage letter or a Trump post.

My nagging question then becomes, 

Can I possibly use a kitchen knife to unscrew the screws?

And what about prying off the cover after using the knife?

Skipping to the end:
Two DIMM slots lay side-by side.
One DIMM slot is filled, the other, empty.

I need one 16GB 5600 CAS 46 DIMM. ("Need" is subjective)

I wrote a blog years ago about memory speed, but memory amounts are missing.

What does windows starve for? 

Somebody wrote the "For a usable experience" part,
then quotes forum users.
I am skeptical.

There are really bombastic lectures about this. 

Windows uses what it can, like molasses spilled on a table, and caches the rest.

I, um ... o, and memory salesmen are real interested in you wanting more memory.

But unless you do what they do, it is very difficult to generalize.

Clearly I do less.
No mining, few games.

I don't need a laptop at all for a bit, and a nice person gave me a case, years ago (whatever they're called, "valise?" "Carrying case"?

So it will be good when this PC dies or during power failures,

but since it'll never play massive games, 16GB might be enough.

Without being able to modify BIOS, the memory must slip in like a ninja and pretend that it was alwayd there, because

With no BIOS-timings access, I'm restricted.

Atari 400

Mine had 16K, and a guy upgraded it to 32K by piggybacking chips.

I still don't know why he upgraded it or why it took so long.
In retrospect I doubt I would have let him because when I did, 

three months later, I sold it to yet another guy.

Commodore 64 FTW!

Guys make videos now saying how Puny 16GB is...8GB is beneath mentioning.

To be fair, the video I just watched was for a desktop, and I've had 32GB for years.
I'll bet that if I really searched, this blog would have said it didn't matter mich (benchmarks went up slightly)

Anyway my laptop w/o games is the focus here.
Unless I could shoehorn in a video card, I doubt I'd see any difference.
