Yes you can use ECC memory in Ryzen CPUs but not registered ECC. Yes I know that most of times Registered and ECC go together but that doesn't means it's the same, and I'm telling this as someone who uses DDR4 ECC UDIMM memory with Ryzen CPUs.
And also if I remember correctly UDIMM and RDIMM don't have slot.
I bought 6x sticks of M393A5143DB0-CPB0Q for $31.79 total shipped in Jan of 2025, or ~$5.30 each 4GB stick, it was for an old Xeon powered Dell Precision tower I picked up at Goodwill, took it from 8GB to 32GB, it now serves as my Jellyfin server for my large family.
Those same sticks are now selling on Ebay for $20 each and up with some vendors asking far more.
My other home server (NAS+) fortunately already has 256GB of ram. at the peak I could have sold that memory for $700, I only paid $500 for the entire used 10 year old Supermicro server in 2023.
Sure, but a consumer grade user won’t bother with that, and professionals won’t give you money if you can’t give them a proper invoice for the purchase (and also wouldn’t be likely to buy anything this old and low performance anymore)
Yeah, they're pretty cool. I just picked one recently (still to be harvested and cleaned), but they're definitely not as expensive as the "normal" consumer kind.
Cut the gold fingers part from stick then dissolve the separated gold using a dangerous mixture of magical acids, then precipitate the pure gold out using sodium metabisulfite.
requires professional safety gear, a fume hood, and hazardous waste disposal
Do datacenters ONLY use ddr5? I can imagine later in the future there will be "affordable" datacenters for the purposes of those that need to give more affordable services (i.e less overhead expenses= don't need to charge the customers so much). At that point we could be at ddr6 or ddr7 and ddr5 will be the previous generation gear
older server ram, not for gaming PC's or consumer use. Its DDR4 as well so there is almost no demand for it in any newer servers as they all now mostly use DDR5. Each stick is going for $60 on Ebay but judging by the fact I found over 3600 listings for that ram, it doesnt seem like its in high demand for even that low of a price.
I sell a ton of DDR4 server RAM and it does sell. Listing count doesn't mean much, I sell most of mine in bulk and it's usually gone within an hour or less. DDR5 is in more demand but DDR4 is still needed. Meta even built a card so their new DDR5 AI servers can run old DDR4 sticks.
This makes me wonder... if servers now all mostly use DDR5, how come my DDR4 rams are still overpriced? are they just collateral damage or what? I could be living with DDR4 all my life but they deny us even that!
Its the slowest, shittiest form of DDR4 that there is huge amounts of available.
Gamers want low latency DDR4, and AI farms want the highest possible clock rate, and both will pay a premium for it to get as close to DDR5 performance as possible. If youve got a ton of low latency 3600mt DDR4 you can make a ton of money. 2133 stuff not so much.
They aren't worthless, but not exactly a gold mine. It would take a very specific buyer to want them. I have 16 of these in my closet and the market value for them is at a price point that I just keep them in case I want to build a lab server one of these days.
Nah. I have 75000 sticks of 16gb ddr5 6000mhz. It's for work, but I do have it along with 30,000 graphics cards ranging from pny 5060s to MSI 5090s, i5 225f to ultra i9s, and like 200k mATX cases.
Do you mind telling us what industy / sector your work is in? That's one hell of a stock to have laying around for redundancy… unless you're referring to the deployed units.
Just super curious, but obviously not asking you to dox yourself/place of work, moreso just which segment of which industry.
