32 GB DDR4 2666 ECC load-reduced DIMM for HPE ProLiant DL560 Gen10 servers
This 32GB DDR4 2666 load-reduced ECC module is built for the HPE ProLiant DL560 G10 server. It targets administrators who need registered memory with error correction for stable operation in multi-socket enterprise workloads. The single 2Rx4 rank design fits one 288-pin slot and runs at the standard 1.20V JEDEC voltage. Buyers who need unbuffered DIMMs or non-ECC memory for consumer platforms cannot use this module.
The module plugs directly into an available 288-pin DDR4 socket on the server motherboard and requires no additional cables, adapters or cooling hardware. Its load-reduced architecture reduces electrical load on the memory controller, freeing headroom for higher total capacities across the remaining channels. Systems that do not support LRDIMM or that are limited to RDIMM populations will not accept this part.
At 1.20V the module draws minimal power for a 32GB LRDIMM, keeping thermal contribution low inside a densely populated chassis. The absence of a heat spreader means airflow from the server fans passes directly over the DRAM packages, so adequate front-to-rear cooling is expected. Under typical enterprise loads the memory operates within JEDEC thermal limits without audible noise from the module itself.

The module runs at CL19 latency, which sets the minimum cycle delay for every read or write operation under continuous load.
At 1.20 V the 32 GB LRDIMM draws modest power and has no heat spreader, relying on server chassis airflow for thermal management.
A 288-pin DDR4 LRDIMM slot in an HPE ProLiant DL560 G10 is required for this 2Rx4 registered ECC module to function.
