DDR4 RDIMM deals — the homelab sweet spot
DDR4 registered memory is where used supply runs deepest: one full generation of Xeon Scalable and EPYC platforms behind current, with pallets of it decommissioned every month. It fits Xeon E5 v3/v4, Xeon Scalable gen 1–2, and EPYC Naples/Rome builds.
Watch the notation, though — sellers write the same stick as 2666, 2666V, or PC4-21300, and a "32GB (2x16GB)" kit is not a 32GB stick. DIMMsum normalizes both before anything reaches the chart.
