128GB DDR5-5600 RDIMM — used server RAM prices

Registered ECC memory (RDIMM) rated at 5600 MT/s — sellers also list this speed as PC5-44800. 128GB sticks fit current DDR5 server platforms (Xeon Scalable Sapphire Rapids and later, EPYC Genoa and later). 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 twice daily.
