    LOADING...

    A-Tech 64GB DDR4-2400 ECC Load Reduced DIMM is a 288-pin, 1.2V 4Rx4 server memory module, suitable for compatible server and workstation systems that support LRDIMM memory and the listed Samsung equivalents.

    Recommended For

    • Server operators running memory-heavy virtualization or database workloads who need more capacity per DIMM and whose server explicitly supports 64GB 4Rx4 DDR4 LRDIMMs.
    • Data-center or homelab builders consolidating multiple services on a DDR4 server who want a 64GB module, after checking the server’s supported DIMM type, rank, speed, and population rules.
    • Administrators replacing a failed Samsung M386A8K40BM1-CRC-class module in a compatible server and seeking a matching 64GB, DDR4-2400, ECC LRDIMM configuration.
    • Workstation or server users running memory-intensive analytics or high-performance computing tasks who need a large ECC memory footprint and have verified LRDIMM support.

    Real-World Use Scenarios

    • A virtualization host is running short on memory as more VMs are added; installed in a compatible server, this module can add capacity for additional or larger VMs, subject to the host’s total memory limits and configuration.
    • A database server has a growing working set or several databases to support; added RAM can give the system more room for database memory and reduce pressure to rely on storage for active data, depending on workload and configuration.
    • A server runs memory-intensive analytics or keeps a large dataset in memory; additional capacity can let more of the working set remain in RAM, when the application and platform are configured to use it.
    • A high-performance-computing server is being expanded for memory-demanding jobs; the added capacity can help accommodate larger jobs or more concurrent work, but does not by itself guarantee faster processing.
    • An owner is upgrading a compatible DDR4 server or workstation one module at a time; this single 64GB module can add memory capacity, but the system must support 4Rx4 ECC LRDIMMs and the required population rules.
