    Samsung LR-DIMM server memory

    The Load Reduced DIMM (LR-DIMM) uses a buffer memory chip, instead of register found on RDIMM. This allows more memory Ranks to be populated on a single module, resulting higher capacity. This type of server memory is beneficial to data intensive applications in data centers, Cloud computing and high-performance computing.

    The Samsung server memory module is manufactured with premium quality components, tested to rigorous standards, and validated in a wide range of systems. This guarantees the best possible stability, reliability and compatibility. Maximize expensive workstation and server investments by inexpensively installing more memory.

    Please note: Not all systems accept LR-DIMM. Please check whether the LR-DIMM is supported before purchase. LR-DIMM cannot be mixed with other memory types including RDIMM, ECC UDIMM and UDIMM.

    The Samsung M386A4G40DM0-CPB0QE is a 32GB DDR4-2133 ECC Registered Load Reduced DIMM for server systems that support 288-pin, quad-rank LRDIMMs.

    Recommended For

    • Owners of compatible DDR4 servers who need a 32GB ECC LRDIMM for a memory expansion or replacement; verify the server’s supported memory type and configuration before buying.
    • Homelab builders running a server that supports 32GB DDR4 LRDIMMs and want to add memory for hosting multiple virtual machines or services.
    • Operators maintaining compatible legacy Xeon servers who need 32GB, 4-rank DDR4-2133 ECC LRDIMMs matching a supported memory configuration.
    • Used-server buyers replacing or expanding an existing Samsung LRDIMM setup, provided the server vendor supports this module and its rank, speed, and DIMM-type configuration.

    Real-World Use Scenarios

    • On a compatible DDR4 server used for virtualization, adding these modules can increase the memory available to virtual machines, letting an administrator host more or larger VMs when RAM is the limiting resource.
    • For a database server that is short on memory, adding supported LRDIMMs can provide more room for the database and its working data in RAM; this may reduce memory pressure, though performance still depends on the full server and workload.
    • When consolidating databases or other server workloads onto fewer machines, these modules can help increase memory capacity on a compatible host, giving administrators more room to allocate memory without relying as heavily on swapping.
    • For a memory-intensive analytics workload, expanding a supported server’s RAM can let more data or jobs fit in memory at once, if the workload is currently constrained by available memory.
    • When upgrading or replacing memory in an older DDR4 server, this module can serve as a 32GB-per-slot capacity addition if the system supports this exact LRDIMM type and its memory-population rules.
