Samsung 16GB 2Rx8 DDR4-2933 ECC RDIMM Server RAM (M393A2K43CB2-CVF) - Used

Samsung 16GB DDR4-2933 ECC Registered RDIMM Server Memory (M393A2K43CB2-CVF) — Server Pull, Bench Tested

Genuine Samsung M393A2K43CB2-CVF 16GB DDR4-2933 ECC Registered DIMM. High-speed Cascade Lake-era server memory. Server pull from production datacenter infrastructure. Each module is bench-tested for POST, ECC functionality, and SPD identification before listing.

DRAM supply context: AI-driven demand has elevated DDR4 server memory pricing through 2026 and is forecast to remain tight through 2027. Tested server-pull modules at this spec deliver enterprise-grade capacity at retail-tier pricing well below the new-module retail floor.

What We Test on Every Module

• POST / boot test — module identifies and trains at rated 2933 MT/s
• ECC functionality — Error Correcting Code validated
• SPD verification — module reports correct capacity, rank, and timing to host BIOS
• Production provenance — pulled from a working server fleet
