32 GB DDR4 2666 ECC LRDIMM

This NEMIX RAM module delivers 32 GB of DDR4 2666 memory in a single 288-pin load-reduced DIMM. It operates at 1.20 V with CL19 latency and includes ECC error correction for data integrity in server environments. The 2Rx4 rank organisation helps maximise capacity per slot on compatible platforms.

Suited for HPE ProLiant XL260a G9 upgrades

This module is validated for the HPE ProLiant XL260a G9 server and similar systems that accept DDR4 ECC LRDIMMs. Builders needing standard RDIMMs, non-ECC memory, or different pin counts should look at other options. It is not intended for consumer desktop boards that lack load-reduced support.

32 GB single-module capacity headroom

One stick provides 32 GB, letting you scale memory in large increments without occupying additional slots. The load-reduced design reduces electrical load on the memory controller, supporting higher total system capacities. Systems limited to lower maximum module sizes or standard registered DIMMs cannot use this part.

Questions about this item

My HPE ProLiant XL260a G9 currently runs a single processor — will one 32 GB 2Rx4 LRDIMM work in that configuration?

The module is validated for the HPE ProLiant XL260a G9 server; install it in a supported DIMM slot following the system’s population rules for single-processor setups.

If I keep my existing DDR4 2666 registered DIMMs and add this 32 GB 2Rx4 load-reduced DIMM, how will the memory subsystem behave?

LRDIMMs and standard registered DIMMs use different buffering; the platform will not run them together in the same channel, so populate each channel with matching module types.

After seating the 288-pin LRDIMM, what should I check in BIOS to confirm the 2666 MT/s CL19 1.20 V operation?

Open the firmware memory information screen and verify the reported speed shows 2666 MT/s, CAS latency 19, voltage 1.20 V, and that ECC is reported as active.
