16GB DDR4-2400 Registered ECC Module

This 16GB DDR4-2400 RDIMM provides registered ECC memory for server platforms requiring PC4-19200 speed. It operates at 1.20V with a CL15 latency and uses a 2Rx4 organisation across 288 pins. The module is built with major-brand components and validated as 100% compatible with the HP 836221-B21 part number.

Suited for HP Server Memory Expansion

Administrators expanding memory in compatible HP servers to support additional virtual machines or reduce paging will benefit from this registered DIMM. Systems that require unbuffered UDIMMs, load-reduced LRDIMMs, or speeds other than DDR4-2400 cannot use this module. Buyers needing capacities beyond 16GB per slot should look at higher-density alternatives.

Third-Party Compatibility Guarantee

The module is sourced from Samsung, SK Hynix or Micron to match OEM specifications and preserve existing service contracts. A lifetime warranty covers the hardware against defects. No additional software, cables or cooling accessories are included with the memory stick.

Questions about this item

Does this 288-pin DDR4 RDIMM require my server board to support registered ECC memory?

Yes — the module is a registered ECC DDR4 DIMM, so the motherboard must accept registered error-correcting DDR4 memory for it to function.

If I add this 16 GB PC4-19200 stick to existing DDR4-2400 modules, will the system run at the lowest common speed?

The module operates at DDR4-2400 CL15 1.20 V; when mixed with other DDR4-2400 DIMMs the memory controller will run all channels at that shared speed and timing.

How can I confirm the 16 GB 2Rx4 module is recognised at full speed after installation?

Check the BIOS memory information or OS tools such as dmidecode — they should report 16 GB, 2Rx4 organisation, DDR4-2400 (PC4-19200) and registered ECC status.
