Samsung M386A4G40DM0-CPB
The 32GB Samsung M386A4G40DM0-CPB uses a quad-rank, load-reduced ECC design to expand server memory capacity and reduce I/O bottlenecks at 2133 MT/s. Its 1.2V LRDIMM architecture allows for higher density configurations than standard RDIMMs, though it cannot be mixed with other ECC types. This module is strictly for server administrators upgrading compatible enterprise systems, not for desktop or laptop use.
