256GB ECC RDIMM kit for servers

This NEMIX RAM kit delivers 256GB of DDR4 memory across eight 32GB registered DIMMs. It targets administrators who need high-capacity error-correcting memory for mission-critical workloads. The modules run at 2933 MT/s with CL21 latency and operate at 1.2V for standard server power envelopes.

288-pin registered modules with 2Rx4 organisation

Each stick uses a 288-pin RDIMM form factor and a dual-rank 2Rx4 layout built from major OEM Samsung, Micron or Hynix chips. No heat spreader is fitted, so airflow in dense chassis remains unimpeded. ECC and register buffering protect data integrity under sustained load.

Upgrade from smaller DDR4 RDIMM configurations

The kit replaces lower-capacity registered DDR4 sets when applications demand more addressable memory per socket. It is not suited for platforms that require unbuffered UDIMMs or for systems limited to speeds below PC4-23400. Buyers needing DDR5 or non-ECC memory should look elsewhere.

Questions about this item

What does the DDR4 2933 PC4-23400 rating mean for real-world throughput?

The modules run at 2933 MT/s with a peak bandwidth of PC4-23400; actual throughput depends on the motherboard's memory controller and populated slot count.

What physical clearance does an 8-module 288-pin RDIMM kit require?

Eight 288-pin RDIMMs occupy eight adjacent DIMM slots; verify your chassis and CPU cooler leave enough height for the bare modules without heat spreaders.

How should the 2Rx4 registered ECC modules be installed to avoid the common population mistake?

Follow the motherboard manual's ranked-DIMM sequence — typically fill one DIMM per channel first, matching rank configuration, before adding the second rank to each channel.
