128GB DDR4 ECC RDIMM kit

This eight-module kit delivers 128GB of DDR4 2933 ECC registered memory for servers and workstations. Each 16GB module uses a 1Rx4 organisation with CL21 latency at 1.2V. The 288-pin DIMM form factor fits compatible server platforms only.

Registered DIMM with single-rank x4 layout

Registered buffering and ECC protect data integrity in multi-socket environments. The 1Rx4 configuration places all chips on one rank, allowing higher densities per channel. Modules install in standard DDR4 DIMM slots; verify your system manual for channel population rules.

Replaces smaller or slower DDR4 RDIMM sets

Upgrading from lower-capacity kits or slower DDR4 speeds adds headroom for virtualisation, databases and compute workloads. The jump is worthwhile when your workload exceeds current memory capacity or when memory bandwidth limits throughput. Not suitable for desktop or laptop systems.

Questions about this item

Does the PC4-23400 rating cap real-world speed at 2933 MT/s?

Yes, the DDR4 2933 modules are specified at PC4-23400, so the effective data rate is 2933 MT/s.

Will the 288-pin registered DIMMs fit a standard server DIMM slot?

Each 16 GB module uses the 288-pin DDR4 RDIMM form factor, matching server and workstation slots that accept registered memory.

What is the correct order for populating the eight 1Rx4 modules across channels?

Follow the system manual's channel population guide; install modules in the recommended slot sequence per CPU to enable multi-channel operation.
