Server Memory Kit

This NEMIX RAM kit provides 256GB of DDR4 server memory across four 64GB LRDIMM modules. It is built for enterprise platforms that require ECC error correction and load-reduced signalling at 3200MHz. The product is not for desktop PCs or workstations that use standard unbuffered DIMMs.

Thermals and Power

Each module operates at 1.2V, a voltage level that helps contain power draw in dense memory configurations. The load-reduced architecture reduces electrical loading on the memory bus, which can lower the thermal contribution of the memory subsystem under normal server workloads.

Sustained Load Behaviour

With a CAS latency of 22 and 4Rx4 organisation, the modules maintain consistent throughput during extended compute tasks such as virtualisation or in-memory databases. The ECC capability continues to correct single-bit errors throughout sustained operation without interrupting service.

Questions about this item

How do I install the 288-pin DDR4 LRDIMM modules in my server and what step is often missed?

Power down the server, open the chassis, align each 288-pin module with the DDR4 slot key, press firmly until both retention clips click, then verify in BIOS that all 256 GB are detected at 3200 MT/s; the step often missed is seating all four 64 GB modules before the first boot.

What maintenance or replacement will this 4Rx4 ECC LRDIMM kit need over its service life?

The modules have no moving parts and require no scheduled maintenance; if a 64 GB stick fails, replace the single module — NEMIX RAM provides a lifetime replacement warranty for the kit.

What limit appears first when this DDR4-3200 CL22 1.2 V kit runs sustained workloads?

The thermal envelope of the 4Rx4 load-reduced design is the first limit; prolonged heavy traffic can raise module temperatures until the server's airflow throttles speed to protect data integrity.
