32GB DDR4 ECC LRDIMM for HPE XL230a G9

This 32GB DDR4 2666 CL19 ECC LRDIMM is built for HPE ProLiant XL230a G9 servers. It uses load-reduced architecture with 2Rx4 organisation to support high-density memory configurations. The module operates at 1.2V and fits 288-pin DDR4 slots. It targets administrators who need validated, single-module capacity expansion.

Sustained load behaviour

Load-reduced buffering reduces electrical load on the memory controller, helping maintain signal integrity when all slots are populated. ECC corrects single-bit errors during continuous operation. The 2666 MT/s data rate and CL19 latency deliver steady throughput for virtualisation and database workloads. Modules are stress-tested under load before shipment.

Capacity per slot constraint

Each module provides 32GB in a single 288-pin LRDIMM, so maximum system memory depends on the number of slots the XL230a G9 exposes. Buyers who need more capacity per slot cannot use this part. Buyers who require unbuffered or registered DIMMs instead of load-reduced modules must select a different type.

Questions about this item

How much power does the 1.2 V 32 GB DDR4 2666 CL19 LRDIMM draw under sustained server load?

The module operates at 1.2 V DDR4 standard voltage; actual power draw depends on the HPE ProLiant XL230a G9 memory controller and workload, so consult the server documentation for precise figures.

What must the HPE ProLiant XL230a G9 already have to accept this 288-pin ECC LRDIMM?

The server needs an available DDR4 LRDIMM slot, a BIOS that supports 2Rx4 32 GB Load Reduced modules at 2666 MT/s, and matching ECC registered memory population rules.

Can this 2Rx4 CL19 2666 MT/s LRDIMM share a channel with older 1Rx4 DDR4 ECC DIMMs in the same HPE server?

HPE ProLiant XL230a G9 memory population rules determine whether mixed ranks and speeds can run together; check the server maintenance guide for supported rank-per-channel configurations.
