Samsung M386A8K40BM1-CRC 64GB DDR4-2400 LP ECC LRDIMM

The Samsung M386A8K40BM1-CRC is a 64GB DDR4-2400 ECC LRDIMM server memory module for administrators upgrading compatible servers that need high-capacity memory.

Recommended For

• Operators expanding a supported DDR4 LRDIMM server for virtual machines or container workloads, where more memory per DIMM can help accommodate additional in-memory instances.
• Server administrators running memory-heavy databases or other workloads that benefit from larger DDR4 DIMMs and whose platform specifically supports 64GB LRDIMMs.
• Organizations increasing RAM capacity in an existing DDR4 server while keeping to its supported LRDIMM type, speed, capacity, and population rules.
• IT teams replacing a matching 64GB DDR4-2400 LRDIMM in a compatible server and seeking the same module class and rated speed.

Real-World Use Scenarios

• On a compatible server running a large database, adding these modules can increase the memory available for database workloads; the practical benefit is less pressure to fit active data into a smaller RAM pool.
• For a virtualization host running several VMs, using supported 64GB LRDIMMs can help raise total installed memory, leaving more room to assign RAM to guest systems before the host reaches its memory limit.
• When consolidating services onto one compatible server, these DIMMs can contribute to a higher memory capacity, allowing more workloads to share the host before memory becomes the limiting resource.
• For a memory-heavy application server, installing supported modules can expand the RAM available to active workloads; this is most useful when the application is constrained by memory capacity rather than processor or storage performance.
• When upgrading a compatible DDR4 server, these modules can add memory in 64GB increments; check the server’s supported LRDIMM type and population rules first, since unsupported memory configurations may not boot.
