16GB DDR4-2933 UDIMM — used server RAM prices

Unbuffered ECC memory (ECC UDIMM — the ECC that fits desktop-socket boards, not interchangeable with RDIMMs) rated at 2933 MT/s — sellers also list this speed as PC4-23400 or 2933Y. 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 median comes from single-stick, fixed-price listings only, so multi-stick lots and auction bids can't skew it. Refreshed from live eBay listings twice daily.
