16GB DDR4-3200 UDIMM — used server RAM prices

As of October 19, 2026, a used 16GB DDR4-3200 UDIMM costs $9.81/GB shipped ($157 a stick) at the low end of eBay's market: one in ten of the 174 live single-stick listings ask that or less. The median ask is $14.19/GB. The low end was $9.83/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 3200 MT/s — sellers also list this speed as PC4-25600 or 3200AA. 16GB sticks fit DDR4 ECC-capable desktop-socket boards (AM4 Ryzen on ASRock/ASUS boards and Ryzen PRO, Xeon E3 v5/v6 and E-2100/E-2200, C236/C246, and NAS units like Synology/QNAP). 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.
