Are you actually selling some of the RAM though?

I was curious with this spike and while the amazon listing for 2x48GB DDR5 that I bought a year or so ago has indeed almost tripled the ebay resale value for similar packages sold recently is all over the map with some close to what I originally paid and some as much as double but probably on average 30-50% increase which is nowhere near the amazon listing.

1 GB RAM = 1 GB RAM man. I am HODLING!

Haha, if I did sell I'd probably sell on /r/homelabsales which is a much more pleasant place to interact.
