HPE 16GB DDR4 LRDIMM ECC Module

This HPE 752371-081 module adds 16GB of DDR4 SDRAM to compatible enterprise switches. It runs at 2133MHz with CL15 latency and operates at 1.20V. Error Checking and Correction protects data integrity in always-on network environments.

Suited for single-module upgrades needing ECC

Administrators who need a 288-pin LRDIMM with ECC for supported HPE switch platforms can use this part. Builders who need unbuffered DIMMs, non-ECC memory, or a different voltage should look elsewhere.

Key spec is the LRDIMM form factor with ECC

The 288-pin LRDIMM design and ECC capability determine whether this module fits the target switch slot. Verify the platform requires LRDIMM rather than standard RDIMM before ordering.

Questions about this item

Does the DDR4-2133 interface cap usable bandwidth in this 16 GB module?

The DDR4-2133 rating sets the maximum data rate at 2133 MT/s; actual throughput depends on the host controller and channel configuration.

What physical slot and clearance does the 288-pin LRDIMM need?

It requires a standard DDR4 288-pin DIMM socket and enough vertical clearance for the taller LRDIMM form factor.

How is the module installed, and what step is often missed?

Align the notch with the key in the slot, press firmly until both retention clips click, then verify the module is fully seated by checking the clips are locked.
