I have one 32GB DDR5 SO-DIMM in my laptop that runs at 5600MHz. Right now it's worth about $500 (can't find a price for an equivalent in my local european webstore, they're all slower), I bought it at 180€. I bought said laptop months before the price skyrocketed. (it's one of the reasons I'm glad I didn't wait for FL16 Gen 2 and bought a Gen 1 even though it's already "outdated")

This meme is... more real than one would expect.
