M386A8K40DM2-CWE Samsung 64GB DDR4-3200 ECC LRDIMM
M386A8K40DM2-CWE is a 64GB DDR4-3200 load-reduced ECC DIMM manufactured by Samsung. This 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 and load-reduced architecture help reduce the electrical load placed on the memory bus in compatible high-capacity server configurations. Each quantity ordered includes one 64GB memory module.

Is M386A8K40DM2-CWE Compatible With My System?
Before ordering, verify that the server, motherboard and processor support 288-pin DDR4 ECC LRDIMM memory. The platform must also support 64GB module capacities and a quad-rank 4Rx4 organization.
An LRDIMM is not the same as a standard RDIMM. Although both 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 within the same system unless the system manufacturer explicitly documents support for that configuration. The module may operate below 3200 MT/s when limited by the processor, motherboard, firmware, installed capacity or memory-channel configuration.
