8GB DDR4-2400 UDIMM — used server RAM prices

As of October 11, 2026, a used 8GB DDR4-2400 UDIMM costs $7.78/GB shipped ($62.26 a stick) at the low end of eBay's market: one in ten of the 97 live single-stick listings ask that or less. The median ask is $13.68/GB. The low end was $8.00/GB on Sep 4, so it's down 3% since.

Unbuffered ECC memory (ECC UDIMM — the ECC that fits desktop-socket boards, not interchangeable with RDIMMs) rated at 2400 MT/s — sellers also list this speed as PC4-19200 or 2400T. 8GB 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.
