Server-grade DDR4 ECC memory kit

This 16 GB kit consists of two 8 GB registered DIMMs built for HP ProLiant DL60 Gen9 and DL80 Gen9 servers. Each module runs at DDR4 2133 MHz with CL15 timings and 1.2 V operation. Error-correcting code and registered buffering protect data integrity in multi-socket configurations.

Sustained-load behaviour with registered buffering

The registered design places a buffer between the memory controller and the DRAM chips, reducing electrical load on the bus during continuous operation. Memory will clock down to run at optimal speeds depending on processor model and number of modules installed, ensuring stability across all populated slots.

Thermals noise and power draw in normal use

Operating at 1.2 V keeps power consumption low and eliminates the need for a heat spreader. The modules generate minimal heat inside the server chassis, allowing standard system airflow to maintain safe temperatures without additional cooling noise.

Questions about this item

Does the 1.2V DDR4-2133 ECC registered kit add noticeable heat or power draw when the ProLiant DL60 Gen9 runs 24/7?

Each 8 GB module operates at 1.2 V with no heat spreader, so the pair draws minimal extra power and relies on the server's existing airflow for cooling.

What server hardware do I already need to install this 288-pin registered DIMM set?

You need an HP ProLiant DL60 Gen9 or DL80 Gen9 with a supported CPU installed, because only 8 DIMM slots are active with one processor and 16 slots with two.

Can I mix these 2Rx8 CL15 RDIMMs with older LRDIMMs already in my DL80 Gen9?

No — the platform prohibits mixing RDIMM and LRDIMM types, so all populated slots must use registered ECC modules like this kit.
