16GB DDR5-5600 UDIMM — used server RAM prices

As of October 19, 2026, a used 16GB DDR5-5600 UDIMM costs $31.56/GB shipped ($505 a stick) at the low end of eBay's market: one in ten of the 61 live single-stick listings ask that or less. The median ask is $40.12/GB. The low end was $31.56/GB on Sep 4, about the same as today.

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 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.
