Eight 96 GB DDR5 5600 CL46 ECC registered DIMMs deliver 768 GB for SuperMicro AI SuperServer motherboards
This 768GB kit contains eight 96GB DDR5 5600 ECC RDIMM modules built for Supermicro MBD-X13DGU AI SuperServer motherboards. Registered 2Rx4 organisation and on-die ECC protect data integrity in multi-socket server and workstation deployments. IT teams specify it when maximum memory capacity per channel is required.
Bare modules without heat spreaders rely on chassis airflow and operate at 1.10V to minimise power draw under sustained AI and HPC workloads. Registered buffering reduces electrical load on the memory controller, helping keep system thermals manageable in dense 1U or 2U enclosures. Silent operation suits noise-sensitive rack rooms.
The 288-pin DDR5 RDIMM form factor installs directly into the Supermicro X13DGU DIMM slots, leaving PCIe lanes free for GPU accelerators and storage controllers. Eight modules populate all channels for balanced bandwidth without requiring additional risers or adapters. Buyers needing higher frequencies or lower latencies should verify platform limits before ordering.

Power down the server, open the chassis, align each 288‑pin module with its slot and press firmly until the retention clips lock; the step most often missed is populating all eight channels in the exact order shown in the board manual so the memory controller trains at 5600 MT/s.
The modules have no heat spreaders and no moving parts, so no scheduled maintenance is required; if a 96GB 2Rx4 RDIMM ever fails, replace only that single module with an identical CL46 1.1V part to keep the eight‑channel configuration balanced.
The registered DDR5 5600 MT/s data rate combined with CL46 latency sets the bandwidth ceiling; once all eight channels are saturated the memory controller cannot push throughput higher without lowering latency or raising frequency, which this kit does not support.
