16GB Registered DDR4 Module

This 16GB DDR4-2133 Registered RDIMM delivers ECC error correction and registered buffering for stable server operation. It runs at PC4-17000 speed with CL15 latency and 1.20V voltage. The module uses a 2Rx4 rank configuration on a 288-pin form factor. It is built with major-brand chips and matches HP part number 726719-S21.

Suited for HP Server Upgrades

This module fits administrators expanding memory in compatible HP servers that require registered ECC DDR4. It is not for desktop PCs or laptops that accept only unbuffered non-ECC memory. Buyers needing higher speeds, larger capacities or different rank layouts should look at other modules. Workstations without registered memory support cannot use this DIMM.

16GB Capacity With Registered Headroom

The 16GB capacity handles typical virtualisation workloads and database buffers in supported HP platforms. Registered signalling reduces electrical load on the memory controller, allowing larger total system memory than unbuffered alternatives. The limit is the 16GB per module ceiling; servers needing more memory per slot must use higher-density RDIMMs.

Questions about this item

Does this 288-pin DDR4 RDIMM require a server motherboard that supports registered ECC memory?

Yes, the module is a registered DDR4 RDIMM with ECC, so the system must accept registered ECC DIMMs at 1.20 V.

Will this CL15 2133 MHz module run at the correct speed if installed alongside slower DDR4 DIMMs already in the server?

The memory controller will down-clock all modules to the lowest common speed, so this 2133 MHz stick will operate at the slower DIMM's frequency.

How can I verify the module is recognised as 16 GB at 2133 MHz with CL15 timing after installation?

Check the BIOS memory information or an OS tool such as dmidecode; it should report 16 GB, 2133 MT/s, CAS latency 15 and registered ECC type.
