16GB DDR5-5600 UDIMM — used server RAM prices

Unbuffered ECC memory (ECC UDIMM — the ECC that fits desktop-socket boards, not interchangeable with RDIMMs) rated at 5600 MT/s — sellers also list this speed as PC5-44800. 16GB sticks fit DDR5 ECC-capable desktop-socket boards (AM5 Ryzen and EPYC 4004, Xeon E-2400, W680/W790). 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.
