M386AAG40AM3-CWE Samsung 128GB DDR4-3200 ECC LRDIMM
M386AAG40AM3-CWE is a 128GB DDR4-3200 load-reduced ECC DIMM manufactured by Samsung. This high-capacity 288-pin server-memory module is designed for compatible enterprise servers and computing platforms that specifically support DDR4 LRDIMM memory.
The module operates at 3200 MT/s with CL22 latency, 22-22-22 primary timings and the standard DDR4 voltage of 1.2V. Its quad-rank 4Rx4 organization uses dual-die package DRAM components to provide 128GB of capacity on one module. Each quantity ordered includes one 128GB memory module.

Is M386AAG40AM3-CWE Compatible With My System?
Before ordering, verify that the server, motherboard, processor and BIOS support 288-pin DDR4 ECC LRDIMM memory. The platform must also support 128GB module capacities and a quad-rank 4Rx4 organization. Support for lower-capacity LRDIMMs does not automatically guarantee support for this module.
An LRDIMM is not interchangeable with a standard RDIMM. Although both module types use a 288-pin DDR4 form factor, their buffering architectures and system 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 supports that configuration. The module may operate below 3200 MT/s when limited by the processor, motherboard, BIOS, installed capacity or memory-channel population.
