NEMIX RAM MR38400-9624K4 384GB (4x96GB) DDR5-4800 CL40 ECC Registered RDIMM memory upgrade

Exact-match DDR5-4800 kit for GIGABYTE MZ73-LM1

This 384 GB kit delivers four 96 GB DDR5-4800 RDIMMs built to the exact rank, voltage and timing the MZ73-LM1 memory controller expects. Registered ECC architecture lets every slot run fully populated at rated speed while correcting single-bit errors on the fly. The modules install directly into the board's 288-pin DDR5 slots without adaptation.

Thermals and power at rated load

Each module operates at 1.1 V, the standard DDR5 voltage, keeping power draw predictable in dense server configurations. No heat spreaders are fitted, so airflow through the chassis determines module temperature under sustained workloads. Registered buffering reduces electrical load on the memory controller, helping maintain stability when all four slots are populated.

Replaces mismatched or lower-capacity RDIMMs

This kit upgrades systems running smaller or mixed-capacity DDR5 RDIMMs that force the controller to down-clock or leave slots empty. The jump is worth it when the workload demands the full 384 GB at native DDR5-4800 with ECC protection. It is not for boards that require UDIMM or SODIMM form factors, nor for platforms that do not support 2Rx4 registered modules at this density.
