16GB DDR4 2933 ECC RDIMM for HP servers

This 16GB DDR4 2933 ECC RDIMM module is built for HP server and workstation platforms that require registered memory with error correction. The single-rank 1Rx4 design operates at PC4-23400 speed with CL21 latency and standard 1.20V voltage. It targets administrators who need to expand capacity in compatible HP systems using major-brand chipsets.

Replaces ten HP part numbers directly

The module serves as a compatible equivalent for HP part numbers P19041-B21, P00920-K21, P00920-B21, P03051-191, P14633-001, P19041-H21, P19254-001, P14117-B21, P03051-091, and P00920-H21. Using this replacement lets you add 16GB of registered ECC memory without sourcing the original HP-branded modules. No extra software or accessories are included in the package.

288-pin DIMM installs in standard DDR4 slots

Installation follows normal DDR4 DIMM procedure: align the notch, press firmly until the latches click, and verify seating. Registered ECC modules must match the platform's memory mode and population rules; mismatched ranks or mixing unbuffered DIMMs will prevent boot. Always confirm the system's qualified vendor list and maximum supported capacity before adding this module.

Questions about this item

Will the 16GB DDR4 2933 ECC RDIMM module itself require any scheduled maintenance or replacement?

No, the solid-state module has no moving parts and is designed for the life of the server; replacement is only needed if a fault occurs or capacity must be increased.

What limit appears first when the 1Rx4 registered DIMM runs at full DDR4 2933 speed continuously?

The memory controller’s maximum supported rank count per channel is reached before the single-rank module hits any thermal or bandwidth ceiling.

How much heat and power does the 1.20V DDR4 2933 RDIMM produce during all-day operation?

At the standard 1.20V the module draws minimal power and generates low heat, allowing passive airflow in a server chassis to keep temperatures in check.
