High-density DDR4 LRDIMM kit

This 768GB kit contains twelve 64GB modules built for servers and workstations that need maximum memory capacity in a single system. It targets IT professionals who run virtualisation clusters, large databases or memory-intensive analytics workloads.

ECC and load-reduced architecture

Error-correcting code detects and corrects single-bit errors to protect data integrity in mission-critical environments. The load-reduced design lowers electrical loading on the memory bus, allowing all twelve modules to operate together at the rated 2133 MT/s without signal degradation.

288-pin registered form factor

Modules use the standard 288-pin DDR4 LRDIMM connector and operate at 1.20V with CL15 latency. The lack of heat spreaders means clearance is minimal, fitting dense server chassis, while the 4Rx4 organisation requires a motherboard qualified for quad-rank load-reduced DIMMs.

Questions about this item

Do the 12x64GB LRDIMMs need any firmware updates or scheduled replacement?

No firmware updates are required for the DDR4 2133 CL15 modules; they are validated once at install and run for the system lifetime.

What limit appears first when the 768GB kit runs at full load continuously?

The memory controller's maximum supported capacity or rank count is reached before the 1.20V LRDIMMs hit a thermal or bandwidth ceiling.

How much heat and noise do the 288-pin 4Rx4 modules add when the server runs all day?

The bare 1.2V LRDIMMs have no heat spreaders and no moving parts, so they add only passive DRAM heat handled by the chassis airflow.
