Only if you actually use that much. You almost certainly don’t.

[-] brucethemoose@lemmy.world 4 points 2 months ago

I do.

I wish I had 192GB, to be honest.

[-] ranzispa@mander.xyz 1 points 2 months ago

What is the need of 192GB?

I often execute calculations on a cluster where I'll need some 500-1000 GB of ram. But I have 32 GB in my workstation and I never felt I needed more.

Everything I need to do I can do: I can be having many browser tabs open, several IDEs, compiling and have a game engine open at the same time.

Only times I fill the ram is when I stress test my software for ram usage, but that is to be expected.

Machine learning/data science stuff.

Local LLMs is half of it.

But that aside, I found myself working with huge files that swapped like crazy on my 32GB of RAM, or were completely infeasible to work with. Janky local experiments I wouldn’t want to run on a cloud instance billed by the minute.

128GB has been a godsend, but I could completely fill 192GB and still swap some if I had it.

But I found there are happy side effects to having so much disk cache, too. For instance, game modding/tinkering has sped up immensely over 32GB. So has hashing for transfers, or other scenarios where it’s useful to already have a file cached in RAM.

Fair, I guess I'd also want some ram if I did not have access to a compute cluster.

But to be fair, for what I do I don't really think you can fit that much ram on a consumer motherboard.

In machine learning I don't generally find memory to be the bottleneck, as long as the GPU can handle it.

But sure, opening huge files can be big trouble.

I can rent cloud stuff, but it's just not worth it for casual/experimental use.

Like keeping Deepseek V4 loaded and hitting it rarely, but I want it to be in my control... it's just easier to do it locally.

Or experiments I launch like 30 times before it works. I'd waste hours moving all my stuff to a cloud instance, configuring it, tinkering with the experiment to get it to launch; the thing would be idle the vast majority of the time. And yeah, I know I can containerize stuff, but some projects I can't even test without a sizable memory pool.

introducing: zram

toss 32 or 64gb at that and call it a day

[-] brucethemoose@lemmy.world 2 points 2 months ago* (last edited 2 months ago)

YMMV.

Big ZRAM absolutely tanks performance for me because it "steals" space that could be used for normal memory.

But if its for squirrling away a bunch of idle processes when multitasking like crazy, yeah, it can be wonderful. Just depends.

[-] dreadbeef@lemmy.dbzer0.com 1 points 2 months ago

ah fair enough, worst case scenario if they dont know what to do with that much ram (I would build a homelab) they could also have a ramdisk

[-] ozymandias117@lemmy.world 1 points 2 months ago* (last edited 2 months ago)

If you're able to have swap, Zswap is supposed to be better.

Zram is intended for devices with no swap

[-] brucethemoose@lemmy.world 2 points 2 months ago

...This appears to be amazing advice.

That's exactly what I was looking for. Thanks!
