128GB DDR4-2666 LRDIMM for Lenovo Servers

This 128GB DDR4-2666 ECC LRDIMM is built for Lenovo-compatible server platforms that require maximum memory density per slot. The 8Rx4 organisation and registered design allow the module to operate at 1.2V while delivering 128GB of capacity. It targets administrators who need to scale virtual machine counts or in-memory databases without adding new chassis.

Sustained load behaviour with 8Rx4 organisation

The 8Rx4 rank structure spreads electrical load across the memory bus, helping the module maintain stability during continuous, high-throughput workloads such as large-scale virtualisation or analytics. ECC protection corrects single-bit errors on the fly, preventing silent data corruption that can accumulate over long runtimes. Registered buffering reduces signal loading on the processor memory controller, supporting reliable operation when all slots are populated.

Upgrades from lower-density RDIMMs or partial fills

This module replaces lower-capacity RDIMMs or partially filled memory configurations when the platform supports LRDIMM topology and the 8Rx4 rank layout. The jump is worth it when the application is limited by total addressable memory rather than raw bandwidth, allowing more virtual machines or larger datasets to reside in RAM. It is not suited for systems that only accept standard RDIMMs or that restrict rank count per channel.

Questions about this item

How much power does a 128GB DDR4-2666 LRDIMM draw at 1.2V during sustained server workloads?

Each module runs at 1.2V, the standard DDR4 voltage, keeping power draw low even when the server runs all day under heavy load.

What motherboard slot and memory-channel configuration must I already have to install this 288-pin 8Rx4 LRDIMM?

You need an available 288-pin DDR4 slot on a server board that supports LRDIMM topology and 8Rx4 rank organisation.

Will this Lenovo-compatible 128GB LRDIMM work alongside older DDR4 RDIMMs already in my system?

Mixing LRDIMMs with standard RDIMMs is not supported; all populated slots must use the same registered-memory type for stable operation.
