HPE XL190r G9 32GB DDR4 ECC LRDIMM

This NEMIX RAM module delivers 32GB of DDR4 2666 ECC LRDIMM memory in a single 288-pin stick. It runs at 1.20V with CL19 latency and uses a 2Rx4 load-reduced design built with major OEM chips. The part is validated for the HPE ProLiant XL190r G9 server platform.

Suited for XL190r G9 slots needing maximum

The load-reduced architecture helps the memory controller support higher total system memory than standard registered DIMMs allow. Buyers who need non-ECC memory, unbuffered DIMMs, or speeds other than DDR4 2666 should look elsewhere. This module will not fit desktop motherboards or laptops.

Deciding spec: 32GB 2Rx4 LRDIMM at DDR4 2666

The 2Rx4 organisation and load-reduced buffering determine whether the XL190r G9 can populate all slots at full speed. Verify the server memory population rules for rank limits per channel before ordering. The 288-pin DDR4 form factor and 1.20V operation match the platform requirements exactly.

Questions about this item

Does the 288-pin LRDIMM fit the HPE ProLiant XL190r G9 memory slots?

Yes, the module is a 288-pin DDR4 LRDIMM built for the XL190r G9 server platform.

What is the correct way to seat the 2Rx4 ECC LRDIMM during installation?

Align the notch with the slot key, press firmly until both retention clips click, then verify the module sits level.

Will the 1.2 V Samsung, Micron or Hynix chips need active cooling later?

The module has no heat spreader and runs at standard 1.2 V; adequate chassis airflow is sufficient.
