128GB DDR4-2400 LRDIMM — used server RAM prices

As of October 2, 2026, a used 128GB DDR4-2400 LRDIMM costs $4.89/GB shipped ($626 a stick) at the low end of eBay's market: one in ten of the 23 live single-stick listings ask that or less. The median ask is $5.40/GB. The low end was $4.89/GB on Jul 5, about the same as today.

Load-reduced ECC memory (LRDIMM) — buffered for high capacity per channel, and not mixable with RDIMMs in the same system rated at 2400 MT/s — sellers also list this speed as PC4-19200 or 2400T. 128GB 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.
