HPE ProLiant DL80 G9 compatible memory

This 32GB DDR4 2666 module is built for the HPE ProLiant DL80 G9 server. It delivers ECC load-reduced registered operation for stable enterprise workloads. The single DIMM format suits single-slot upgrades or filling empty banks. IT teams specify it for memory-bound virtualisation and database tasks.

1.2V operation with standard DDR4 thermals

Running at 1.20V, the module stays within normal DDR4 power limits for server DIMMs. No heat spreader is fitted, so airflow across the PCB handles cooling in the DL80 G9 chassis. Load-reduced buffering reduces electrical load on the memory controller without adding active components. Typical server fan profiles keep temperatures in the expected range.

288-pin LRDIMM with 2Rx4 organisation

The 288-pin DDR4 LRDIMM form factor matches the DL80 G9 memory slots exactly. Dual-rank by four (2Rx4) organisation provides density while keeping signal integrity at 2666 MT/s. CL19 latency is standard for this speed grade and registered ECC class. No extra cables or adapters are required; the module seats directly in the server board.

Questions about this item

How do I install the 32GB DDR4 2666 LRDIMM in an HPE ProLiant DL80 G9, and what step is often missed?

Power down the server, open the chassis, align the 288-pin notch with the DIMM slot key, press firmly until the ejectors lock, then verify the module appears at 2666 MT/s in the BIOS memory configuration screen — skipping the BIOS check is the common oversight.

What maintenance or replacement will the 32GB ECC LRDIMM need over its service life?

The module has no heat spreader and no moving parts; maintenance is limited to keeping server air filters clean so the 1.2 V DRAM stays within thermal limits, and replacement is only required if a correctable ECC error count crosses the platform firmware threshold.

What limit appears first when the 2Rx4 LRDIMM runs sustained workloads on the DL80 G9?

The memory controller caps bandwidth at the rated 2666 MT/s (PC4-21300) with CL19 latency, so throughput ceiling is reached before the 1.20 V supply or the dual-rank x4 organisation hits thermal or electrical limits.
