Server Memory Upgrade

This 16GB DDR4-2666 ECC Registered RDIMM targets administrators who need to expand capacity in compatible HP servers. The module delivers 16GB at PC4-21300 speed with CL15 latency and 1.20V operation. It suits workloads that demand error correction and registered signalling for stability.

HP Compatible Assurance

The stick carries part number 867855-B21 equivalence and uses major-brand Samsung, SK Hynix or Micron components. Third-party sourcing means the module meets OEM specifications while preserving existing service contracts. Buyers who require vendor-locked firmware or proprietary thermal sensors should verify support before purchase.

Registered RDIMM Build

A 288-pin registered design adds a buffer that reduces electrical load on the memory controller, allowing larger populations per channel. Single-rank 1Rx4 organisation keeps signal integrity high at 2666 MT/s. Systems that accept only unbuffered UDIMMs or require different rank configurations cannot use this module.

Questions sur cet article

Will the 1Rx4 ECC registered RDIMM need replacement under normal server loads?

The module uses major-brand Samsung, SK Hynix or Micron chips and carries a lifetime warranty; replacement is only required if a chip fails or capacity needs increase.

What limit appears first when the 2666 MHz CL15 kit runs at full load continuously?

The DDR4-2666 JEDEC speed ceiling is reached before any thermal or power limit on this 1.20 V registered DIMM.

How much heat and power does the 1.20 V 288-pin DDR4 module produce during all-day operation?

At the rated 1.20 V the 16 GB RDIMM draws minimal power and generates low heat, well within standard server airflow limits.
