A friend and I bought RAM for our aging servers at eBay in 2024. That was 512GB (16x32GB -- we split it equally) of DDR4 ECC 2133MHz, registered. For… $536.86 plus shipping.
Somehow it feels like we got a pretty good deal, in retrospect. (My server has been since replaced, and I can tell you, 256GB of DDR5 ECC was more than that! There's been a further doubling or two of prices since I bought, though. I think I could maybe sell half the RAM and finance the entire server…)
One would think just some classes and forms of RAM increased in price. I have 128 GB (2 x 64GB DDR5 SO-DIMM) in my home NAS. Home NAS. Those nice ugreen DXP8800 Plus thingamabobs. It'd be over 2k euros for RAM alone now. Ridiculous. Add to that two SN850X 4TB SSDs, and 8 (+1 unpacked spare) IronWolves Pro and it's now a serious worth.

No end in sight.
Not much cheaper than DDR5.
