High-Capacity DDR4 ECC LRDIMM Kit

This NEMIX RAM kit delivers 768 GB of DDR4 server memory across twelve 64 GB LRDIMM modules. It targets IT professionals and data-centre operators who need maximum registered ECC capacity for virtualisation hosts, in-memory databases or high-density compute nodes. The load-reduced design helps maintain signal integrity on heavily populated memory channels.

Upgrading from Standard Registered DIMMs

The 4Rx4 load-reduced architecture replaces conventional registered DIMMs when a platform requires more ranks per channel than standard RDIMMs allow. The jump is worth it when your workload demands the full 768 GB and the motherboard qualification list explicitly supports LRDIMM population rules for all twelve slots. Standard RDIMM kits cannot reach this density on the same hardware.

DDR4 3200 Interface Limits

The PC4-25600 interface caps transfer rates at 3200 MT/s, so throughput scales with channel count rather than per-pin speed. CL22 latency and 1.2 V operation are fixed by the DDR4 JEDEC standard for this data rate. Total capacity is bounded by the twelve 288-pin slots available on qualified server boards; configurations needing more memory must move to a platform with additional channels or a newer memory generation.

Questions about this item

Does the 288-pin LRDIMM form factor require a server motherboard with LRDIMM-compatible slots?

Yes, these 288-pin DDR4 LRDIMM modules need a server motherboard that explicitly supports Load Reduced DIMMs; standard RDIMM or UDIMM slots will not accept them.

Do the twelve 64 GB modules need to populate specific slots in sets of four for quad-rank operation?

Install all twelve modules in the motherboard's designated LRDIMM slots following the manual's population order; quad-rank 4Rx4 modules often require specific channel groupings for stability.

Will the Samsung, Micron or Hynix DRAM chips inside need active cooling under sustained server loads?

The modules have no heat spreader; ensure the server chassis provides adequate airflow over the DIMM area to keep chip temperatures within specification.
