4GB DDR4-2400 RDIMM — used server RAM prices
Registered ECC memory (RDIMM) rated at 2400 MT/s — sellers also list this speed as PC4-19200 or 2400T. 4GB sticks fit DDR4 server platforms (Xeon E5 v3/v4, Xeon Scalable gen 1–2, EPYC Naples/Rome). Prices below include shipping. The low end is the 10th-percentile ask: one in ten single-stick listings ask that much per GB or less, so it's a price you can find near the top of a search sorted by price. It and the median come from single-stick, fixed-price listings only, so multi-stick lots and auction bids can't skew them. Refreshed from live eBay listings twice daily.
