256 GB ECC RDIMM kit

This NEMIX RAM kit delivers 256 GB of DDR5 registered ECC memory across four 64 GB modules. It targets servers and workstations that require error correction and signal buffering for stable operation under sustained loads.

1.1 V operation and DDR5 efficiency

Each module runs at 1.10 V while operating at 4800 MT/s with CL40 latency. The lower voltage and on-die power management of DDR5 reduce heat output compared with previous generations, helping keep system thermals manageable in dense configurations.

288-pin registered DIMM form factor

The 288-pin RDIMM design fits DDR5 server boards that support registered memory and ECC. Builders must verify motherboard qualification for 64 GB density and 2Rx4 organisation; the kit does not suit platforms limited to unbuffered UDIMMs or lower maximum capacities.

Questions about this item

How do I install the 288-pin DDR5 RDIMM modules and what step is often missed?

Align the notch on each 288-pin DDR5 RDIMM with the slot key, press firmly until the retention clips click, and ensure the motherboard is powered off and unplugged before starting.

What maintenance or replacement will the 4x64GB kit need over time?

No routine maintenance is required; the modules either operate reliably for the system's life or are replaced if a memory test reports correctable ECC errors.

What limit appears first when the 256GB kit runs at 4800MT/s continuously?

The CL40 latency at 1.10V is the primary timing constraint under sustained load; thermal throttling is unlikely without a heat spreader in a server chassis with adequate airflow.
