128GB DDR4-2666 LRDIMM — used server RAM prices

Load-reduced ECC memory (LRDIMM) — buffered for high capacity per channel, and not mixable with RDIMMs in the same system rated at 2666 MT/s — sellers also list this speed as PC4-21300 or 2666V. 128GB sticks fit DDR4 server platforms (Xeon E5 v3/v4, Xeon Scalable gen 1–2, EPYC Naples/Rome). Prices below include shipping; the median comes from single-stick, fixed-price listings only, so multi-stick lots and auction bids can't skew it. Refreshed from live eBay listings every 6 hours.
