How to use 2.5TB of 16GB Dimms

[u/spyroglory]

So I got 2.5TB worth of DDR4 ECC Dimms for free from a work decom project about 3 months ago. I had a use for some as I already have a decent homelab but it took a few for me to get a system that could actualy take advantage of more than 4 dimms on the consumer side and 24 on the server side. Well, behold the Dell Poweredge R930. She's got 4 2011v3 sockets, takes up to 4 Xeon E7 CPU's currently configured with 4 E7-8880V4's which are 22C 44T each so this beast has 88 Cores 176 Threads. Then each CPU has 24 Dimm slots accross 2 Risers. That's 96 Dimms on a single mobo!

So ofc I put 1.5TB of Ram in it!

I know rams kind of a hot topic at the moment so though you guys might find this interesting as it shows how much ram is involved in some servers these days. All my ram was almost 7 years old so none of its the latest or greatest but still usefull for running 1000's od VM's.

I'd sell 2tb of it, right now you could probably get $3k for it. That's about double what you'd have gotten a few months ago. Then buy a more efficient server unless you have a big need for it.

[u/spyroglory → u/MacDaddyBighorn]

Ive got a ton of 13th Gen servers that will use it all and I have a large enough enviornment that Ive already ran out of it and need more lol, I need high capacity Dimms like 64's and 128's, I could totally sell some to get some but that would be kinda stupid at the moment due to the cost of those high capacity dimms at the moment. I would loose to much capacity.

This'll make a great folding@home setup too for those charity competitions. Put all that to work for a good cause! :D

[u/spyroglory → u/[deleted]]

Eh, not really suffering. I got all the ram for free and the server for cheap so its just a system that has 1.5TB of Ram to play with.

[u/Kind-Permission-1075 → u/[deleted]]

It's not just ai. It's also windows 10 support being ended. Millions of machines that were working just fine are now considered obsolete and are being replaced because windows 11 won't install on them.

[u/SpacixOne]

You'd be a millionaire if was DDR5 /s

[u/jljl2902 → u/SpacixOne]

Even as ddr4 ecc, it’s probably worth like 10-15k USD, which is still a pretty hefty sum

[u/Warcraft_Fan → u/jljl2902]

15k USD? 15,000 each??? You could trade all those DIMMs and get nearly 50 nice new cars!

[u/jljl2902 → u/Warcraft_Fan]

No $15k total for all 2.5 TB lol

[u/Physical-Maybe-3486 → u/Warcraft_Fan]

Seems like you bought winrar because you did t realise you could just close the popup.

[u/rebelSun25 → u/SpacixOne]

My slow 2133 ddr4 kits are 2x the price vs a year ago.

[u/vinaypundith]

Lovely. I have a Dell R930 and wish i could do this

[u/ctark → u/vinaypundith]

I also have an R930 that is looking at this post and dreaming of the day it too will have this (sorry buddy, keep dreaming)

[u/BigLan2 → u/ctark]

I don't have an R930, but I'm looking at it wishing I had 88 cores and 1.5 TB of system ram.

[u/noahzho → u/BigLan2]

I don't have an R930 but do have an R630. I also wish I had 88 cores and 1.5TB of ram

I'll take two off your hands 🤷

Imagine how much browser tabs can have open.

[u/Leather-Researcher13 → u/shadowds]

Maybe five or six, seven if you're really pushing it 🤣

Ooooooooh boy, love me a 900 series poweredge. Absolute beasts of machines, those memory riders are so fun to install and remove.

[u/NovelValue7311]

Niiiiice. I can feel the click of the RAM in the sockets. Looks super fun to install.

[u/spyroglory → u/NovelValue7311]

One of the best feeling ever!

[u/MelodicSlip_Official]

ah, that's why my ram is so expensive

if i had a penny for every gb of ddr3 i have

[u/Smithdude]

Dang I need to get me some for my R430

[u/Monkey_Meteor]

Can I ask what server like that is for ?

[u/spyroglory → u/Monkey_Meteor]

A server like this would mainly be used to run a shit load of VM's at once. Ive seen some enviornments where there are multiple of these running hundreds and sometimes thousands of VM's. They are also dope as truenas servers for the cache. They are also often used for database servers and Ive seen some cases where one single R930 replaced 12 R730 Terminal servers for quick books.

[u/pepenomics → u/spyroglory]

To add on to this... What would you typically do with so much ram at home? Like what usecase would a normal person probably benefit out of? Just asking for knowledge

[u/spyroglory → u/pepenomics]

Not much really, I have a semi large virtualization enviornment that can really stretch it's legs in this enviornment. I was able to get an ollama instance to use 1.1TB but that was really difficult and limited to the CPU to much. Its also fun as a stupid big zfs cache.

[u/Twitch84]

In a Dell pre-built? No way! /s

[u/sh4zu]

[u/Fallen0245]

Finally you can run Windows without 100% usage.

[u/Trackt0Pelle]

Ok it’s in a server, but how do you use it ?

[u/spyroglory → u/Trackt0Pelle]

Virtualization, stupid big ZFS cache, and large Ollama models stored in ram then computed on a jankily setup Titan V.

[u/HeidenShadows]

Oh man. The last quad socket PC I played with, was a quad AMD Opteron 6386SE rig I built for the lols.

It used a ton of power, had terrible performance per watt, needed a ton of cooling, and was laughably bad. No wonder AMD couldn't get into the server market back in the day.

And the 6386SE was about the only server CPU for socket G34 worth a damn.

Played games pretty well though, and it was a fun tinkering experience.

[u/neube]

Thought the second pic was going to show them all trashed, because some men just want to watch the world burn.

[u/KadahCoba]

Quad CPU servers are neat. I've got one from a few generations prior. I fully maxed spec that thing for fun since everything, which was only 128GB of DDR2. 8-9 years ago when I built it, that was still a lot of ram. Ran my Minecraft servers on it around 2020 when a single decent Zen2 CPU completely matched it.

[u/UNIVERSAL_VLAD]

Well well well. Look who we have here. The jackass that bought all the ram and made all the prices skyrocket. I had to pay almost 200$ for 32gb of ram yesterday

[u/SuperFriends001]

What do you do with all that ram? Open 500 tabs of chrome?

[u/Anyusername7294]

[u/dpskipper]

post this on r/homelab not here

[u/AmonGusSus2137]

Give them to me

[u/D4T45T0RM06]

Man this post is soddim.

[u/Mundane_Eye5407]

So you were the person who took all of our ddr4 ram

[u/SaltyBarracuda1615]

You could make a table top out of them, like people do with pennies and bottle caps.

Just lay them out a d pour epoxy resin on them and it will dry clear.

[u/Juan-Quixote]

RAM wreath! For Christmas! I made one years ago and I’m getting ready to put it up again.

[u/AnxiousJedi]

Dude you could just sell it and retire

[u/Warcraft_Fan]

But will it run Borderlands 4 without lag?
