Server ECC memory kit

This 128GB kit contains two 64GB DDR4 2933 ECC registered DIMMs built for HP ProLiant Gen10 servers. It targets administrators who need to expand memory capacity in supported rack or carrier-grade systems without mixing memory types.

Registered ECC requirement

The modules are 2Rx4 registered ECC RDIMMs and will not work in standard desktops or alongside unbuffered or load-reduced memory. Compatibility is limited to the listed HP ProLiant DL160 Gen10, DL180 Gen10, DL380 Gen10 Carrier Grade, DX170r Gen10 and XL450 Gen10 models.

Thermals and power

Operating at 1.2V with no heat spreaders, the modules rely on server chassis airflow for cooling. Power draw scales with the 128GB total capacity and registered buffer, while acoustic output is determined by the host system fan curves rather than the memory itself.

Preguntas sobre este artículo

Will 2933 MHz DDR4 run at that speed in my HP ProLiant DL380 Gen10?

The modules are rated for DDR4 2933 (PC4-23400) and are backward compatible with 2666 MHz, 2400 MHz and 2133 MHz; the server's memory controller and CPU generation determine the actual operating frequency.

Does the registered ECC RDIMM design limit which memory slots I can populate on a DL180 Gen10?

Registered ECC RDIMMs are required for these ProLiant servers and cannot be mixed with unbuffered or load-reduced DIMMs; follow the platform's population rules for 2Rx4 modules.

Will the 288-pin 2Rx4 sticks fit the DIMM slots on an HP ProLiant XL450 Gen10?

Yes — each module is a standard 288-pin DDR4 RDIMM with 2Rx4 organisation, matching the slot and rank requirements of the listed ProLiant models.
