Odd, I have a Celeron J3455 which according to Intel only supports 8GB, yet I run it with 16 GB

Yup. Gateway E-475M. It has trouble transcoding some plex streams, but it keeps chugging along. $5 well spent.

I faced that only with different editions of Windows limiting it by itself.

Aw yep, bought an old HP pro-lient something something with 2 old-ass intel xeons and 64GB ram for practically nothing. Thing's been great. It's a bit loud but runs anything I throw at it.

The oldest hardware I'm still using is an Intel Core i5-6500 with 48GB of RAM running our Palworld server. I have an upgrade in the pipeline to help with the lag, because the CPU is constantly stressed, but it still will run game servers.

Yep, mspencer dot net (what little of it is currently up, I suck at ops stuff) is 2012-vintage hardware, four boxes totaling 704 GB RAM, 8x10TB SAS disks, and a still-unused LTO-3 tape drive. I’ll upgrade further when I finally figure out how to make proper use of what I already have. Until then it’s all a fancy heated cat tree, more or less.

Me on a RPi4.

2012 Mac Mini with a fucked NIC because I man handled it putting in a SSD. Those things are tight inside!

Why didn't you post this before I bought the RAM?!

My home Kubernetes cluster started out on a Core i7-920 with 8 GB of memory.

Upgraded to 16 GB memory

Upgraded to a Core i5-2400S

Upgraded to a Core i7-3770

Upgraded to 32 GB memory

Recently Upgraded to a Core i5-7600K

I think I'll stay with that for rather long...

I did however add 2 Intel NUCs (gen 6 and gen 8) to the cluster to have a distributed control plane and some distributed storage.

I met someone that was throwing out old memory modules. Literally boxes full of DDR, DDR2 modules. I got quite excited, hoping to upgrade my server’s memory. Yeah, DDR2 only goes up to 2GiB. So I am stuck with 2×2GiB. But I am only using 85% of that anyways, so it’s fine.

My i5 6600k will turn 10 years old this year. I'm fortunate because upgrading to 32 GB should keep it running for a while still.

Oldest I got is limited to 16GB (excluding rPis). My main desktop is limited to 32GB which is annoying, because I sometimes need more. But, I have a home server with 128GB of RAM that I can use when it's not doing other stuff. I once needed more than 128GB of RAM (to run optimizations on a large ONNX model, iirc), so had to spin up an EC2 instance with 512GB of RAM.

Wow, it's been a long time since I had hardware that awful.

My old NAS was a Phenom II x4 from 2009, and I only retired it a year and a half ago when I upgraded my PC. But I put 8GB RAM into that since it was a 64-bit processor (could've put up to 32GB I think, since it had 4 DDR3 slots). My NAS currently runs a Ryzen 1700, but I still have that old Phenom in the closet in case that Ryzen dies, but I prefer the newer HW because it's lower power.

That said, I once built a web server on an Arduino which also supported websockets (max 4 connections). That was more of a POC than anything though.

I used to self host some stuff on an old 2011 iMac. Worked fine, actually

I'm hosting a minio cluster on my brother-in-law's old gaming computer he spent $5k on in 2012 and 3 five year old mini-pcs with 1tb external drives plugged into them. Works fine.

What hardware are you using where the cpu says you are limited to 4gb?

Even a 25 year old Pentium 4 supports 8GB.
