As of October 19, 2026, a used 48GB DDR5-5600 UDIMM costs $23.92/GB shipped ($1,148 a stick) at the low end of eBay's market: one in ten of the 13 live single-stick listings ask that or less. The median ask is $37.50/GB. The low end was $20.79/GB on Sep 4, so it's up 15% since.
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. 48GB 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.
