Even DDR4. Just checked, I bought a non-ECC 1x32go stick for my homelab on August 25th, priced 78€ on Amazon. Same offer is now at 229€. Yeah I guess I'll wait before updating to 64gig then
I don't think DDR4 is even being manufactured anymore, so the rush is clearing out that inventory for good.
It reminds me very much of the crypto mining craze, when there was a run on GPUs and one couldn't be had for any less than 5x it's MSRP. I know that eventually passed and so too will this but it still sucks if you had been planning to purchase RAM or anything needing it.
