768GB DDR4 ECC LRDIMM Kit

This kit provides 768GB of DDR4 ECC LRDIMM memory across twelve 64GB modules. It runs at 2666 MT/s with CL19 latency and 1.20V voltage. The load-reduced design targets servers and workstations that require high-density registered memory with error correction.

Upgrading from lower-capacity RDIMM sets

Replacing smaller RDIMM kits with this 4Rx4 LRDIMM kit increases total capacity while reducing electrical load on the memory controller. The jump is worth it when the platform supports LRDIMM and the workload demands more than standard registered modules can deliver.

Twelve-module population requires full slot count

Installing all twelve modules fills every slot on compatible boards, so the CPU and chipset must support the full population at 2666 MT/s. Mixing with other ranks or speeds usually prevents boot, and the lack of heat spreaders means airflow across the DIMMs must be adequate.

Preguntas sobre este artículo

Does this 288-pin DDR4 LRDIMM kit need a server motherboard with LRDIMM slots?

Yes, the kit uses 288-pin DDR4 LRDIMM modules that require a server motherboard with LRDIMM-compatible memory slots.

What is the correct population order for the twelve 4Rx4 modules?

Install the twelve 64GB 4Rx4 modules following the motherboard manual’s LRDIMM population sequence; skipping the prescribed slot order is the most common mistake.

Will the 1.20V operating voltage change over the kit’s lifespan?

The modules run at 1.20V from the factory; no voltage adjustment or periodic replacement is required under normal server operation.
