HP-compatible DDR4-2666 ECC UDIMM

This 16 GB unregistered module runs at DDR4-2666 with CL15 latency and 1.20 V operation. It targets administrators who need to expand memory in HP servers that accept PC4-21300 ECC UDIMMs. The 2Rx8 organisation delivers standard density for dual-channel configurations. Major-brand DRAM ensures the same component quality HP uses in its own labelled parts.

Verify slot type and rank limits

Confirm the server accepts unregistered ECC UDIMMs rather than registered or load-reduced variants. Check the platform’s maximum rank-per-channel allowance, because this 2Rx8 module counts as two ranks. Ensure the BIOS is current enough to initialise PC4-21300 speed without down-clocking. Matching modules will be supplied so mixed-rank populations are avoided.

Sustained load behaviour

ECC corrects single-bit errors continuously during long compute runs, preventing silent data corruption. The 1.20 V JEDEC voltage keeps power draw stable across extended workloads. Major-brand ICs from Samsung, SK Hynix or Micron maintain timing integrity at 2666 MT/s under thermal stress. Lifetime validation testing backs reliability for mission-critical deployments.

Questions about this item

Does the 16GB DDR4-2666 ECC UDIMM come as a single stick or a kit, and is anything else required for installation?

This listing is for one 16GB module. No extra parts are needed; it installs directly into a standard DDR4 UDIMM slot on a compatible HP system.

How do I decide between the different speed or capacity options shown for this part?

The module is specified as 16GB PC4-21300 DDR4-2666MHz CL15 2Rx8 1.2V. Choose this version when your HP server or workstation requires exactly that speed, rank and voltage.

What does the CL15 rating on this 2666 MT/s module mean for actual system responsiveness?

CL15 means the memory controller waits 15 cycles at 2666 MT/s before reading the first word of a burst, which is the standard latency for this DDR4 speed grade.
