M386ABG40M51-CAE Samsung 256GB DDR4-3200 ECC LRDIMM
M386ABG40M51-CAE is a 256GB DDR4-3200 load-reduced ECC DIMM manufactured by Samsung. This high-capacity 288-pin server-memory module is designed for compatible enterprise servers that specifically support DDR4 3DS LRDIMM memory.
The module operates at 3200 MT/s with the standard DDR4 voltage of 1.2V. Its octal-rank 8Rx4 organization uses four-high 3DS stacked DRAM components to provide 256GB of capacity on one module. Each quantity ordered includes one 256GB memory module.

Is M386ABG40M51-CAE Compatible With My System?
Before ordering, verify that the server, motherboard, processor and BIOS support 288-pin DDR4 ECC 3DS LRDIMM memory. The platform must specifically support 256GB modules and an octal-rank 8Rx4 organization. Support for ordinary DDR4 LRDIMMs does not automatically guarantee support for this capacity.
An LRDIMM is not interchangeable with a standard RDIMM. Although both module types use a 288-pin DDR4 form factor, their buffering architectures and platform requirements differ. Do not install this module in a system designed only for RDIMM, ECC UDIMM, non-ECC UDIMM or SODIMM memory.
Do not mix LRDIMMs and RDIMMs unless the server manufacturer explicitly documents support for that configuration. The module may operate below 3200 MT/s when limited by the processor, motherboard, BIOS, installed capacity or memory-channel population.
