Samsung M386A4G40DM1-CRC5Q

The Samsung M386A4G40DM1-CRC5Q is a 32GB DDR4-2400 ECC registered LRDIMM for compatible servers that use 288-pin, 4Rx4 memory.

Recommended For

• Server administrators replacing or expanding memory in a DDR4 server that specifically supports 32GB, 2400 MT/s LRDIMMs; confirm the server’s supported part type and configuration before buying.
• Operators of LRDIMM-compatible virtualization hosts that need ECC server memory for workloads running multiple virtual machines, provided 32GB modules fit the host’s capacity plan.
• Teams maintaining older Intel Xeon E7 v4 servers that use DDR4 LRDIMMs; Intel’s validation list includes the related Samsung M386A4G40DM1-CRC 32GB module.
• Database or analytics server operators using an LRDIMM-capable platform who need ECC memory and have verified that 32GB DDR4-2400 modules meet their capacity and speed requirements.

Real-World Use Scenarios

• When expanding a compatible DDR4 server, this 32GB LRDIMM adds memory for larger workloads; the server must support LRDIMMs and the required 4Rx4 configuration.
• For a virtualization host running several memory-hungry VMs, adding supported LRDIMMs can provide more room for guest workloads before the host reaches its memory limit; the actual capacity depends on the server’s configuration.
• For a database or analytics server that needs more working memory, adding compatible LRDIMMs can leave more data available in memory and reduce pressure to fetch it from storage; results depend on the application and system configuration.
• When replacing a failed module in an existing server, this DIMM may suit a system configured for 32GB DDR4-2400 ECC LRDIMMs; check the server’s supported memory list and match its module-type and population rules.
• In a home lab built around compatible enterprise server hardware, adding these modules can increase memory available for self-hosted services or test VMs; they are not a general-purpose desktop RAM upgrade, and RDIMMs and LRDIMMs may not be mixed.
