Server-grade capacity

This NEMIX RAM kit delivers 512 GB across two 256 GB LRDIMM modules built for DDR4 3200 servers. Error-correcting code and load-reduced architecture target enterprise workloads that demand maximum density per channel. The 8Rx4 organisation and 1.2 V operation suit qualified platforms needing registered ECC memory. It is not for desktop PCs or consumer motherboards.

Sustained-load behaviour

Load-reduced buffering reduces electrical load on the memory controller, helping stability when all ranks are populated at 3200 MT/s. CAS latency of 22 cycles applies across the full capacity during continuous throughput. Major-brand Samsung, Micron or Hynix ICs underpin consistent timing under prolonged server duty cycles.

Thermals and power

Operating at 1.2 V keeps per-module power draw within standard DDR4 limits for 288-pin LRDIMMs. The registered design shifts drive strength to the buffer, lowering signal integrity stress on the host. Typical server airflow handles the resulting heat without specialised cooling requirements.

Questions about this item

How much power does the 1.2 V DDR4 3200 kit draw when the server runs continuously?

Each module operates at 1.2 V; total system draw depends on the platform's memory controller and workload, so consult the server vendor's power budget for the 512 GB configuration.

What server features are required to use 288-pin ECC LRDIMM modules?

The platform must support DDR4 3200 LRDIMM with 8Rx4 organisation, ECC and registered signalling; verify the motherboard's qualified-vendor list before installation.

Can the 8Rx4 LRDIMMs share channels with older 4Rx4 RDIMMs in the same server?

Mixing LRDIMM and RDIMM types on one memory controller is not supported; all populated slots must use the same module technology for stable operation.
