64GB DDR5-6400 RDIMM — used server RAM prices

As of October 3, 2026, a used 64GB DDR5-6400 RDIMM costs $42.97/GB shipped ($2,750 a stick) at the low end of eBay's market: one in ten of the 51 live single-stick listings ask that or less. The median ask is $53.91/GB. The low end was $31.23/GB on Jul 5, so it's up 38% since.

Registered ECC memory (RDIMM) rated at 6400 MT/s — sellers also list this speed as PC5-51200. 64GB sticks fit current DDR5 server platforms (Xeon Scalable Sapphire Rapids and later, EPYC Genoa and later). 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.
