High-capacity server memory kit

This NEMIX RAM kit delivers 384GB of DDR4 capacity across twelve 32GB LRDIMM modules. It targets administrators scaling virtualisation hosts, database clusters or high-performance computing nodes that require maximum DIMM density per channel.

Load-reduced DDR4 LRDIMM format

Each module uses a 288-pin DDR4 LRDIMM interface with 4Rx4 organisation and a 1.2V operating voltage. The load-reduced buffer reduces electrical loading on the memory controller, allowing all twelve slots to be populated without signal degradation. Systems must provide DDR4 LRDIMM-compatible slots and a supporting chipset to recognise the 4Rx4 configuration.

Tested multi-vendor DRAM and lifetime replacement

Modules are built with Samsung, Micron or Hynix DRAM and are stress-tested under load before shipping. The kit carries a lifetime replacement warranty backed by US-based IT support staff. No heat spreaders are included, so airflow in the server chassis must be sufficient for bare-module cooling.

Questions about this item

Will the 4Rx4 rank configuration limit how many of these 32 GB modules I can populate per channel?

Each module is a 4Rx4 load-reduced DIMM, so the memory controller sees only one electrical load per rank; the practical limit per channel depends on your server's qualified vendor list and BIOS revision.

Do these LRDIMMs run hotter or draw more power than standard registered DDR4 when the server is under continuous load?

At 1.20 V the voltage matches standard DDR4, and the load-reduced buffer reduces electrical loading on the bus, so sustained power and thermals are comparable to regular RDIMMs of the same speed.

My motherboard has 288-pin DDR4 slots — is that the only requirement for this kit to work?

The board must support DDR4 2133 LRDIMM modules with ECC and 4Rx4 organisation; consumer or workstation boards that only accept UDIMM or RDIMM will not post with these modules.
