I bought a couple of terabytes of RAM and now I feel like one of those crypto-whales haha. It's just sitting there in the corner. One was a lucky one, too, because I tried to negotiate a guy to sell me a system with less RAM but he wouldn't discount it much. Now it pays for most of the cost of the damn thing.

These spikes do happen. I remember one for hard drives after a storm. The surprising thing for me is how cheap a super-powerful Epyc is these days. But then you need to fill the 12 RAM slots and that becomes more costly. Funny times.

You don't NEED to fill the 12 ram slots. My personal 1U has an Epyc 9124 and only 4 of the 12 ram slots filled. I figured, ram will only get cheaper with time so I can fill the remaining 8 slots in the future. Turns out I was wrong, but regardless, the server runs fine on 4 sticks.

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.
