  • Octal-rank 3DS stacking fits maximum density into a single 288-pin module
  • 2 V operation matches standard DDR4 voltage for efficient power use

Single 128GB module for DDR4 servers

This single 128GB module is built for DDR4 servers and workstations that require ECC load-reduced memory. It will not work in desktop or laptop systems. The octal-rank 3DS design lets a single DIMM deliver very high capacity for memory-intensive server workloads.

Sustained load with ECC load-reduced design

The load-reduced architecture reduces electrical loading on the memory bus, helping the module maintain stability during continuous server workloads. ECC corrects single-bit errors in real time, protecting data integrity across long-running tasks. CL21 latency at 2933 MHz supports consistent throughput under sustained demand.

Install in validated server slots only

Installation follows standard 288-pin DDR4 DIMM seating, but the system must explicitly support 128GB ECC LRDIMM modules with 2S4Rx4 3DS organisation. Compatibility fails when the platform does not qualify this rank and density combination. Consult the system manual for correct channel population rules before fitting the module.

Frågor om den här produkten

How much power does the 128GB DDR4 2933 module draw at its 1.20V rating?

The module operates at the standard DDR4 voltage of 1.20V. Actual power draw depends on server workload and memory controller utilisation, but the low-voltage design helps limit heat output in dense configurations.

What server memory slots and channel population rules must I check before installing this 288-pin LRDIMM?

Your server must support DDR4 ECC Load Reduced DIMMs with 2S4Rx4 octal-rank 3DS/TSV organisation. Consult the system manual for qualified vendor lists, maximum capacity per slot and required channel population order.

Can I mix this 2933 MT/s octal-rank LRDIMM with existing lower-rank DDR4 RDIMMs in the same server?

Mixing Load Reduced and standard Registered DIMMs is not supported. All populated slots must use identical LRDIMM rank structure and speed; otherwise the memory controller will disable the mismatched channels.
