Samsung 32GB 2Rx4 DDR4-2133 ECC RDIMM Server RAM (M393A4K40BB0-CPB) - Used

Samsung 32GB DDR4-2133 ECC Registered RDIMM Server Memory (M393A4K40BB0-CPB) — Server Pull, Bench Tested

Genuine Samsung M393A4K40BB0-CPB 32GB DDR4-2133 ECC Registered DIMM. Broadwell/Skylake-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.
