128GB DDR4 2933MHz ECC LRDIMM for HPE Servers

This 128GB DDR4 module runs at 2933MHz with CL21 latency and 1.20V operation. It uses a 288-pin LRDIMM form factor with 4DRx4/4Rx4 rank configuration and includes ECC error correction. The module is built as a direct replacement for HPE part numbers P18454-B21, P11057-1A1, P11057-6A1, P19047-B21, P19047-H21, and P19047-K21.

Upgrading from lower-capacity DDR4 LRDIMMs

Replacing smaller LRDIMMs with this 128GB module increases total memory capacity per slot, which is valuable for virtualization hosts and database servers that benefit from fewer populated slots. The jump is worth it when your workload demands maximum density and your platform supports 128GB LRDIMMs at 2933MHz. It does not suit systems limited to RDIMM or lower-density modules.

Fits 288-pin DDR4 LRDIMM server slots

The module installs in standard 288-pin DDR4 DIMM slots that support load-reduced memory. It requires a server platform qualified for 128GB LRDIMMs at 2933MHz with 1.20V operation. No heat spreader is present, so airflow across the module must be provided by the system chassis. Population rules and maximum per-channel limits depend on the specific server model.

Preguntas sobre este artículo

Will the 288-pin DDR4 LRDIMM fit my server's memory slots?

This module uses the standard 288-pin DDR4 DIMM form factor and requires a slot that supports Load Reduced ECC memory at 1.2V.

What is the correct way to seat the 128GB module so the ECC LRDIMM initialises?

Align the notch with the slot key, press straight down until both side clips click, and confirm the BIOS detects the full 128GB at 2933MHz.

When should I plan to replace this 128GB DDR4 2933MHz ECC LRDIMM?

Replace it if memory diagnostics report uncorrectable ECC errors, the server fails POST with this module installed, or a firmware update requires a different rank configuration.
