    MRDIMM benefits

    Optimize

    Overall data center total cost of ownership (TCO) is optimized by enabling higher core-count processors per server rack while maintaining critical capacity per core and bandwidth per core metrics.

    Accelerate

    Memory-intensive workloads are accelerated by boosting performance with best-in-class DIMM bandwidth.

    Scale

    Server performance can scale by accelerating task completion time with improved task energy.

    Achieving data transfer rates of up to 8.8K MT/s

    MRDIMM's 8.8K MT/s data transfer rates

    Providing a 39% bandwidth upgrade for platforms looking to DDR5 RDIMM data rates1

    MRDIMM's 39% increase in bandwidth

    Delivering up to 40% lower latency for capacity- and bandwidth-sensitive workloads2

    MRDIMM's 40% lower loaded density

    Technology Enablement Program for DDR5 MRDIMM

    The Technical Enablement Program (TEP) for DDR5 MRDIMM offers a path into Micron for early access to technical information and support, electrical and thermal models, and memory products to aid in the design, development and introduction of next-generation computing platforms.

    Frequently asked questions

    MRDIMM — sometimes called MR DIMM — refers to multiplexed-rank DIMM, which is where dual-rank DDR5 modules are combined with a multiplexer buffer and a memory controller to increase speeds beyond DDR5 specifications. 

    No. JEDEC has not yet released the standard for MRDIMM. This is the first version of MRDIMM that supports Intel® Xeon® 6 processors.

    When JEDEC releases the MRDIMM standard, Micron will support a JEDEC-compliant version.

    No. It is only compliant on the Intel® Xeon® 6 processors.
