16GB DDR4-2133 RDIMM — used server RAM prices

As of October 2, 2026, a used 16GB DDR4-2133 RDIMM costs $4.69/GB shipped ($75.00 a stick) at the low end of eBay's market: one in ten of the 352 live single-stick listings ask that or less. The median ask is $6.50/GB. The low end was $3.13/GB on Jul 5, so it's up 50% since.

Registered ECC memory (RDIMM) rated at 2133 MT/s — sellers also list this speed as PC4-17000 or 2133P. 16GB sticks fit DDR4 server platforms (Xeon E5 v3/v4, Xeon Scalable gen 1–2, EPYC Naples/Rome). 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.
