The MDRRWM4QDBC2-3G000 is an enterprise-grade 96GB DDR5-6400 (PC5-51200) Registered DIMM (RDIMM) engineered for memory-intensive datacenter workloads, AI inference, and virtualization. Operating at 6400 MT/s at an energy-efficient 1.1V, this dual-rank module leverages non-binary 24Gb DRAM dies to maximize per-socket memory capacity without the thermal and latency penalties of through-silicon via (TSV) stacking. It features on-module power management (PMIC) and complete end-to-end ECC protection for robust 24/7 mission-critical operations.
The MDRRWM4QDBC2-3G000 is architected around JEDEC DDR5 standards utilizing cutting-edge non-binary 24Gb monolithic DRAM dies arranged in a 2Rx4 (dual rank, x4 bit width) organization. In standard DDR5 topology, the memory interface is split into two independent 32-bit subchannels, each augmented with 8 bits of sideband ECC (40 bits total per subchannel, 80 bits per rank). To achieve 96GB capacity across two ranks with x4 data widths, the module uses 20 dual-die packages (DDP) containing 40 total 24Gb dies (32 for data, 8 for ECC). An onboard Registering Clock Driver (RCD) buffers command, address, and clock signals to minimize capacitive bus loading on the host memory controller.
DDR5 departs from legacy DDR4 design by shifting power regulation from the motherboard directly onto the module via an enterprise Power Management IC (PMIC), which converts a 12V host supply into granular 1.1V VDD, VDDQ, and 1.8V VPP rails. System health and telemetry are monitored via an integrated SPD Hub with built-in thermal sensors. Data integrity is guarded at multiple tiers through On-Die ECC (ODECC) inside each 24Gb DRAM die—handling localized single-bit flaws—complemented by traditional sideband ECC managed by the host server CPU to correct multi-bit transmission faults. The part number decodes to an enterprise DDR5 RDIMM ('MDRR'), wide-bus architecture, 96GB non-binary capacity ('QD'), and JEDEC DDR5-6400 timing speed bin ('3G000').
Always verify against your server's qualified vendor list (QVL).
Non-binary 96GB RDIMMs utilize 24Gb DRAM dies rather than standard 16Gb or 32Gb silicon. This provides 50% more memory density than standard 64GB modules per slot, filling the gap between 64GB and 128GB modules while avoiding the higher cost and thermal profiles of multi-die TSV/3DS stacking.
Yes. JEDEC DDR5 modules are fully backward-compatible and will automatically downclock to match the maximum speed supported by the server memory controller, motherboard topology, and population configuration.
Yes. Because 96GB is a non-binary memory density, the server motherboard requires updated BIOS and processor microcode (such as AMD AGESA or Intel MRC supporting 24Gb die addressing) to correctly initialize and train the module.
