HP Compatible 16GB DDR4-2666 RDIMM

This 16GB DDR4-2666 ECC Registered RDIMM is built for HP server platforms needing reliable memory expansion. It targets administrators who want to maximise installed capacity without replacing existing infrastructure. The module meets OEM specifications and maintains service contract validity. It uses major-brand DRAM components from Samsung, SK Hynix or Micron.

16GB capacity at PC4-21300 speed

The single 16GB rank runs at DDR4 2666 with CL15 latency and 1.20V operation. It comfortably handles virtualisation workloads and reduces swapping by expanding total system memory. Performance scales linearly until all memory slots are populated or the memory controller reaches its maximum supported capacity. Beyond that point, additional modules cannot be addressed by the platform.

Third-party module with lifetime warranty

The module is guaranteed compatible with systems requiring the HP 840757-091 part number. It ships as a 100% HP-compatible alternative that preserves the original service agreement. A lifetime warranty covers the DIMM for the duration of its deployment. No additional software or accessories are included with the memory stick.

Questions about this item

Will this 288-pin DDR4-2666 RDIMM run at the correct speed when mixed with existing CL15 modules in my server?

Yes, the module operates at 2666 MT/s with CL15 latency and 1.20 V, matching the timing and voltage of other CL15 DDR4-2666 registered DIMMs so the memory controller can train all ranks at the same frequency.

How can I confirm the 16 GB registered ECC module is recognised and error-correcting after installation?

Check the BIOS or UEFI memory information screen — it should show 16 GB per DIMM, DDR4-2666 speed, registered mode and ECC enabled; the OS memory test or dmidecode will also report ECC capability and the correct 1Rx4 organisation.

Does the single 16 GB stick ship with any extra parts or do I need to buy a heatsink or bracket separately?

Only the 288-pin RDIMM itself is included; no heatsink, bracket or additional hardware is supplied or required for standard server DIMM slots.
