16 GB DDR4-2666 ECC RDIMM for HPE servers

This 16 GB registered DDR4 module runs at 2666 MHz with CL19 latency and 1.20 V operation. It is built for HPE server and workstation platforms that require ECC RDIMM memory. The 2Rx4 organisation and 288-pin form factor match the HPE 835955-X21, 835955-H21 and 835955-K21 part numbers.

Sustained load behaviour

Registered buffering and on-die ECC keep data integrity stable during continuous workloads such as virtualisation, database processing or scientific computing. The module is stress-tested under load before shipment to verify reliable operation over extended periods. Major-brand Samsung, Micron or Hynix DRAM chips provide consistent timing at the rated PC4-21300 speed.

Pre-order checklist

Confirm your system accepts DDR4-2666 registered ECC RDIMMs and that the memory slots support 2Rx4 modules at 1.20 V. Verify the maximum supported capacity per slot and the total number of available 288-pin slots. Check the HPE service manual for any population rules or firmware requirements before installation.

Questions sur cet article

How much power does this 1.2V DDR4 RDIMM draw when the server runs continuously?

Each module operates at 1.2V, the standard DDR4 voltage, so power draw stays low even under sustained 2666MHz workloads in HPE servers.

What must the motherboard provide for this 288-pin ECC registered DIMM to function?

The board needs DDR4 RDIMM slots that support registered ECC memory and a 2666MHz memory controller; the 2Rx4 organisation is handled by the module itself.

Can this 2Rx4 PC4-21300 module share a channel with 1Rx4 or 2Rx8 sticks in an HPE platform?

Mixed-rank populations are platform-dependent; HPE's own memory guides list which rank combinations are validated for each server model.
