HPE ML350 G9 server upgrade

This 32GB DDR4 2666 ECC LRDIMM module is built for the HPE ProLiant ML350 G9 server. It adds a single 32GB stick to compatible systems, raising total capacity toward the 192GB maximum. The part number ML21300-324K1 identifies the exact configuration for this platform.

Load-reduced 288-pin form factor

The module uses a 288-pin LRDIMM design with 2Rx4 organisation and operates at 1.20V. Load-reduced buffering reduces electrical load on the memory bus, allowing higher densities per channel. No heat spreader is fitted, so airflow in the server chassis handles cooling directly.

ECC stability at 2666 MT/s

Error-correcting code detects and corrects single-bit errors during operation, protecting data integrity in mission-critical workloads. Rated at PC4-21300 with CL19 latency, the module runs at standard DDR4 voltage and draws minimal power under typical server loads.

Questions about this item

What DDR4 speed and PC4 rating does this LRDIMM run at?

This module operates at DDR4 2666 with a PC4 21300 data-rate, the maximum standard speed supported by the HPE ProLiant ML350 G9 memory controller.

What physical slot and pin count does this 32 GB module require?

It uses a 288-pin DDR4 LRDIMM form factor that fits the standard DDR4 DIMM slots on the ML350 G9 motherboard.

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

Power down the server, open the chassis, align the notch on the 288-pin edge connector with the slot key, press firmly until both ejector clips lock, then verify in BIOS that all 32 GB are recognised at 2666 MT/s.
