High-density DDR4 LRDIMM kit

This NEMIX RAM kit delivers 768GB across twelve 64GB DDR4 2933 LRDIMM modules. It is built for enterprise servers and workstations that require large memory footprints with ECC protection. The load-reduced design helps reduce electrical load on the memory bus in heavily populated configurations.

Sustained-load behaviour

Each module runs at 1.20V with CL21 latency and a 4Rx4 organisation using major OEM DRAM chips. The LRDIMM buffer absorbs ranking overhead so signal integrity remains stable when all twelve slots are filled. Modules are stress-tested under load before shipping to verify reliability in continuous operation.

Installation practicalities

The 288-pin DDR4 form factor fits standard server DIMM slots, but the 4Rx4 rank structure demands a motherboard and BIOS qualified for quad-rank LRDIMMs. Systems limited to dual-rank or RDIMM-only memory will not support this kit. Always confirm the platform's qualified vendor list before purchase.

Questions about this item

What is the operating voltage and registered design of this 768GB DDR4 2933 kit?

The kit runs at 1.20V and uses a load-reduced registered design (4Rx4) to reduce electrical load on the memory controller.

What motherboard slot type and ECC support are required for these 12 modules?

A server motherboard with 288-pin DDR4 LRDIMM slots and ECC support is required; standard desktop boards will not accept them.

How does the CL21 latency of these 2933MT/s modules affect throughput in a multi-channel server?

At CL21 the modules deliver PC4-23400 bandwidth; actual throughput depends on the platform's memory-controller configuration and channel population.
