HP Compatible 16GB DDR4-2133 RDIMM

This 16GB registered DDR4 module operates at 2133 MT/s with CL15 latency and 1.20V power. It uses a 2Rx4 organisation and 288-pin form factor with ECC for data integrity. The part matches HP 753221-S21 and is built with major-brand DRAM chips.

For servers needing HP-qualified registered ECC

Suits administrators upgrading or repairing compatible HP systems that require registered DDR4 RDIMMs at this speed and rank configuration. Not for workstations or desktops that accept only unbuffered UDIMMs. Not for platforms requiring a different voltage, pin count, or memory generation.

Registered DDR4 RDIMM with ECC

The registered buffer and ECC capability determine whether this module functions in a given server; systems expecting unbuffered non-ECC UDIMMs will not POST with this part installed. Verify the platform requires registered ECC DDR4 before purchase.

Questions about this item

Does my server need DDR4 288-pin registered DIMM slots to use this 16GB module?

Yes, this is a 288-pin DDR4 registered RDIMM that requires a server platform supporting registered ECC memory at 1.2V.

Can I mix this CL15 2133MHz stick with slower DDR4 modules already installed?

The system will run all modules at the speed of the slowest installed kit, so this 2133MHz module will down-clock to match older DDR4.

How can I verify the module is running at PC4-17000 with ECC active after installation?

Check the BIOS memory information or OS tools such as dmidecode to confirm 2133MHz speed, CL15 timing, 1.2V voltage and ECC enabled status.
