16GB DDR3-1866 RDIMM — used server RAM prices

As of October 3, 2026, a used 16GB DDR3-1866 RDIMM costs $1.81/GB shipped ($29.00 a stick) at the low end of eBay's market: one in ten of the 145 live single-stick listings ask that or less. The median ask is $2.50/GB. The low end was $1.88/GB on Jul 5, so it's down 3% since.

Registered ECC memory (RDIMM) rated at 1866 MT/s — sellers also list this speed as PC3-14900. 16GB sticks fit DDR3 server platforms (Xeon E5/E7 v1–v2, Opteron 6000 era). 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.
