High-Capacity DDR5 ECC RDIMM Kit

This NEMIX RAM kit provides 512GB of registered DDR5 memory across four 128GB modules. It operates at 6400MHz with a CL52 latency and 1.1V voltage. The 2Rx4 organisation and ECC support target data-integrity workloads on the Supermicro SYS-122HA-TN-LCC platform.

Suited for memory-bound server tasks

The 512GB capacity serves virtualisation hosts, in-memory databases and large-scale simulation nodes that exceed standard DIMM limits. Builders needing non-registered UDIMMs, lower-density kits or consumer DDR5 speeds should evaluate alternatives. Modules lack heat spreaders, so chassis airflow must handle sustained thermal load.

Steady throughput under load

Registered buffering and on-die ECC maintain signal integrity during continuous read/write cycles at the rated 6400MHz data rate. The 1.1V operating point keeps power draw predictable across all four slots during extended compute windows. CL52 timing remains stable without throttling when the memory controller sustains full bandwidth.

Questions about this item

Does this 512GB DDR5 6400MHz kit require a Supermicro SYS-122HA-TN-LCC motherboard with 288-pin DDR5 RDIMM slots to function?

Yes, the kit is built for the Supermicro SYS-122HA-TN-LCC and fits 288-pin DDR5 RDIMM slots on that platform.

Can I add this 4x128GB 2Rx4 kit alongside existing DDR5 RDIMMs of a different capacity in the same server?

The modules are 2Rx4 registered ECC DDR5; mixing ranks or capacities depends on the motherboard's memory population rules, so consult the system manual before combining.

How do I verify the 6400MHz CL52 1.1V settings are active after installing the four 128GB modules?

Enter the BIOS or use a hardware information tool to confirm the memory reports DDR5-6400, CAS latency 52, 1.1V and 512GB total across all channels.
