HPE Apollo 4200 G9 server memory

This 32GB DDR4 2666MHz ECC LRDIMM module is built for the HPE Apollo 4200 G9 server platform. It delivers registered, load-reduced memory with error correction for stable operation in multi-socket enterprise environments. The single-rank 2Rx4 organisation and 1.2V voltage match the platform's native memory subsystem.

Load-reduced ECC architecture

Load-reduced DIMM technology reduces electrical load on the memory bus, allowing higher total capacity per channel than standard registered modules. On-die ECC detects and corrects single-bit errors without software overhead, protecting data integrity during sustained workloads. The CL19 latency and PC4-21300 rating align with the server's qualified memory profile.

32GB per module, 2TB system ceiling

Each module provides 32GB; the platform supports up to 2TB when fully populated with 256GB LRDIMMs. This density suits virtualisation hosts, in-memory databases and large-scale analytics where memory capacity drives throughput. Workloads that exceed the 2TB limit or require faster than 2666MHz speeds will need a different server generation.

Questions about this item

Will the 32GB 2Rx4 LRDIMM module need firmware updates or battery replacement later?

The module has no battery and requires no firmware updates; ECC error correction runs in hardware for the life of the DIMM.

What limit appears first when the 2666MHz LRDIMM runs at full load continuously?

The DDR4 2666 JEDEC voltage of 1.2V sets the thermal ceiling; sustained throughput caps at the rated PC4-21300 bandwidth before any throttling.

How much heat and noise does the 288-pin LRDIMM produce in a HPE Apollo 4200 G9 running all day?

The load-reduced design lowers electrical load on the memory bus, so the module runs at standard DDR4 thermals with no active cooling and zero audible noise.
