128GB DDR4 LRDIMM for Servers

This module delivers 128GB of DDR4 2933 ECC Load Reduced memory in a single 288-pin DIMM. It targets administrators upgrading compatible server platforms that require registered LRDIMM architecture for high-capacity configurations.

Verify Platform LRDIMM Support

Confirm the server motherboard and processor support DDR4 LRDIMM modules at 2933MT/s with CL21 timing and 1.20V operation. The 4DRx4/4Rx4 rank structure demands specific memory controller capability; mixing with standard RDIMM or UDIMM types will prevent boot.

Single-Module Capacity Expansion

Each 128GB stick occupies one DIMM slot, freeing remaining slots for further expansion within the platform's maximum memory limit. The Load Reduced design reduces electrical load on the memory bus, allowing higher total system capacities than standard registered DIMMs in supported servers.
