HP Compatible 16GB DDR4 RDIMM

This Brute Networks module is a 16GB PC4-21300 DDR4-2666 registered DIMM built with major-brand components. It is designed for HP servers requiring ECC registered memory and matches HP part number 840756-091. The module operates at 1.20V with a CAS latency of 15. It targets administrators upgrading existing compatible HP infrastructure.

Verify 288-Pin DDR4 Slot And Registered Support

Before ordering confirm your server accepts 288-pin DDR4 registered RDIMMs and supports 2Rx8 organisation at 2666 MT/s. The system must handle registered ECC modules at 1.20V. Mixing registered and unbuffered memory is not supported. Check the platform qualified vendor list for this exact part number equivalence.

Sustained Load Stability With Major Brand Chips

Under continuous operation the module maintains rated 2666 MT/s throughput with CL15 timing at 1.20V. Major-brand Samsung SK Hynix or Micron ICs provide consistent signal integrity during extended workloads. Registered buffering reduces electrical load on the memory controller for stable multi-DIMM configurations. ECC corrects single-bit errors throughout sustained duty cycles.

Questions about this item

What comes in the box and is anything else needed to install this 288-Pin DDR4 RDIMM?

The module itself is supplied; no extra brackets, cables or cooling parts are required — just an available registered-DIMM slot on a compatible HP server.

How do I decide between the 16 GB 2666 CL15 2Rx8 registered stick and other capacities or speeds?

Choose this exact 16 GB PC4-21300 CL15 2Rx8 registered module when your HP server requires that precise speed, rank and voltage combination; different capacities or timings will not match the validated configuration.

What does the PC4-21300 2666 MT/s rating deliver once the RDIMM is seated in the server?

It provides 16 GB of ECC registered memory running at 2666 MT/s with CL15 latency at 1.20 V, giving the bandwidth and error correction the platform expects for stable operation.
