High-Capacity Registered ECC Kit

This NEMIX RAM kit delivers 768GB across twelve 64GB DDR4 RDIMM modules for servers and workstations that require registered ECC memory. It targets IT professionals deploying virtualisation hosts, database clusters or high-density compute nodes where maximum registered capacity per channel is needed. The modules operate at DDR4 3200 with CL22 latency and 1.20V voltage.

Thermals and Power in Operation

Each module runs at the standard 1.20V DDR4 voltage without a heat spreader, relying on chassis airflow for cooling in typical server enclosures. Registered buffering reduces electrical load on the memory controller, helping to keep system power draw predictable under sustained multi-threaded workloads. The kit is validated under load to ensure stable operation at the rated speed.

Build and Mounting Implications

The 288-pin RDIMM form factor fits only motherboards with registered DDR4 DIMM slots; it will not work in unbuffered consumer boards. Twelve modules occupy a full complement of slots on many dual-socket platforms, so population rules and channel balance must be followed during installation. Chips are sourced from major OEM suppliers and every module is stress tested before shipment.

Questions about this item

How do I install the 12 DDR4 3200 RDIMMs into my server and which step is often missed?

Power down the server, open the chassis, align each 288-pin module with the keyed slot and press firmly until the latches click; the step often missed is confirming the motherboard supports 768 GB total and the correct 2Rx4 population order before powering on.

What maintenance or replacement will the 64 GB ECC RDIMMs need during their service life?

The modules have no heat spreader and no moving parts, so no scheduled maintenance is required; replacement is only needed if a module fails ECC correction or the server’s memory diagnostics report a hard error.

What limit appears first when the 12-module kit runs at 3200 MT/s CL22 1.2 V under sustained load?

The first limit is the platform’s maximum supported memory bandwidth and rank-per-channel capability; if the memory controller cannot address all 12 ranks at 3200 MT/s, it will down-clock the kit to a lower speed.
