  • 288-pin LRDIMM form factor fits server and workstation slots
  • JEDEC and RoHS compliant for warranty-safe upgrades

Capacity and compatibility

This kit provides 512GB of DDR4 ECC LRDIMM memory across eight 64GB modules rated at 2400MHz CL17. It is built for servers, workstations and NAS systems that require load-reduced registered DIMMs and will not function in standard desktop computers.

Sustained operation

Load-reduced buffering reduces electrical load on the memory controller, allowing all eight modules to run at the rated 2400MHz speed under continuous multi-threaded workloads. ECC protection corrects single-bit errors in real time, maintaining data integrity during extended uptime.

Upgrade path

The kit replaces lower-capacity DDR4 LRDIMM sets or expands populations that currently run at 2133MHz, with backward compatibility at that speed. The jump is worthwhile when virtualisation density, in-memory databases or large dataset caching demand the full 512GB configuration.

Soalan tentang produk ini

How much heat and power does the 1.2V LRDIMM draw when the server runs continuously?

Each 64GB module operates at 1.2V, the standard DDR4 voltage, so the 512GB kit adds minimal heat and power load during all-day server workloads.

What motherboard features are required for these 4Rx4 ECC LRDIMMs to function?

The board must provide 288-pin DDR4 slots that support ECC Load Reduced memory and 4Rx4 organisation; standard desktop boards without LRDIMM support will not work.

Will the 2400MHz CL17 modules run stably in a system that currently uses 2133MHz DDR4?

Yes, the kit is backward compatible with 2133MHz systems and will operate at the lower speed while retaining ECC Load Reduced functionality.
