Serious question, what does RAM help with in the context of self hosting? I recently bought 32G for my server, and it’s DDR3 ecc so it’s so cheap I could have afforded 64 but I just kept wondering what will I use it for? I rarely go north of 6G usage and that’s with half a dozen services, a Minecraft server etc… I just don’t know what kind of services are RAM hungry.

I am glad I bought 128gb of ram last year.

VMs mostly. What are you hosting on Minecraft that isn’t using >=4 gigs?
Also ZFS.

oh yeah i see how that can be hungry

Just a vanilla server i play on with my son, it’s got 2G and i haven’t noticed anything out of the ordinary. Chunk gen is slow-ish but i suppose that’s CPU-bound.
BTW i exagerated in my initial comment, i looked at the machine and it’s sitting just under 8G of used RAM.
Also ZFS
Jesus christ 😅 no idea if you’re jesting

Probably not a lot.
My system idles at 3gb.
But then I do AI stuff and it needs 15-80gb. And I do data analyses that can use a lot.
Zos_Kia@jlai.lu 4 hours ago
Yeah i specifically don’t do any AI workloads on my server, that would be stupid slow with my old ass hardware. But my buddy (who’s a bit impulsive with money) bought two Spark GX10s and we’re likely to get some fun out of them :)

My use case might not be very relatable, but I run a bunch of stuff cached in ramdisk.
One example is if my jellyfin server has to transcode something, I have it use ramdisk instead of my SSD for the transcoding cache.
Zos_Kia@jlai.lu 4 hours ago
I see, that’s interesting. I do a lot of transcoding but offline so i don’t have usage for such a cache. I’ve tested various storage solutions but on my setup, transcoding is always CPU-bound, even on old ass HDDs the bottleneck is never I/O.

I do reencode bluray remuxes too, and also then use ramdisk for it.
I’ve just, always had enough ram to do it so I’ve stuck with it. And the ram is probably gonna take the wear better than SSDs do.
I also use it for download cache for some things, smaller things like music and books/manga.

I bought 3 kits of ddr5 last January before i realized the approved vendor list actually mattered (I’ve never had this happen before). I was too lazy to return them at the time because you can never have too much memory laying around.

I have 1.5tb of ecc ddr4 and don’t know what to do with it. Work decom’d a bunch of servers and I took ram and storage

And here I thought $399 for a 4TB Samsung NVMe 990 Pro was a bit too expensive. Little did I know. I’m so glad my friend talked me into impulse purchasing it last year. What I’m more annoyed about is not picking up HDDs for my NAS last year, I refuse to pay NVMe prices for HDDs.

Wouldn’t it have been cheaper to buy a few smaller ones and a PCIe card?
fuckwit_mcbumcrumble@lemmy.dbzer0.com 5 hours ago
Then you’re losing pcie lanes, and you have to deal with split storage or software raid which doesn’t always work the best.
Breezy@sopuli.xyz 3 hours ago
Yup, and originally I was also aiming to put together a full SSD NAS, so I wanted to use multiple 4TB sticks for that since it was reasonably priced (at the time) for the amount of storage and speed.

Same, I wish I’d bought two.

I am angry at myself for delaying the purchases of a mini PC about 4 months ago /:

If you buy now you can still brag about missing the next price increase when South Korea runs out of helium for chip production in 2 weeks.

Gee I wonder who else has a lot of tappable helium- ah, right. russia.

Russians aren’t brown skinned people tho. We almost exclusively bomb brown skin people.

Arguably not the best timing on that.

Me too, I was waiting for a good deal in a GMKtec EVO-X2, but that is not going to happen.
