HP Compatible Server Memory

This 16GB DDR4-2666 registered DIMM is built for HP servers requiring part number 835955-B21. It targets administrators who need to expand memory capacity in supported platforms using validated third-party modules.

Thermals and Power Draw

Operating at 1.20V, the module follows standard DDR4 voltage levels for registered server memory. ECC and registered buffering add minimal overhead while maintaining signal integrity under sustained workloads.

Bundled Value

The unit ships as a standalone 288-pin RDIMM with major-brand DRAM from Samsung, SK Hynix or Micron. Compatibility is guaranteed for systems accepting this specification, preserving existing service contracts without additional software or accessories.

Questions about this item

How do I install this 288-pin DDR4 RDIMM and which step is commonly missed?

Align the notch on the module with the key in the server DIMM slot, press straight down until both retention clips click, then verify the system BIOS recognises the full 16GB at DDR4 2666 speed.

What maintenance or replacement will this registered ECC module need over time?

No scheduled maintenance is required; if a correctable ECC error count rises, replace the individual 16GB RDIMM rather than the whole set.

What limit appears first when this CL15 1.2V module runs sustained workloads?

The DDR4 2666 transfer rate and CL15 latency set the throughput ceiling before voltage or thermal limits are reached.
