32GB DDR4 ECC RDIMM for HP Servers

This 32GB DDR4 3200 ECC registered DIMM is built for HP server and workstation platforms that require registered memory with error correction. It suits administrators upgrading compatible HP systems to handle larger workloads and improve data integrity.

Straightforward DIMM installation

The module uses a standard 288-pin DDR4 DIMM form factor and installs like any registered DIMM. Issues usually arise when the target system expects unbuffered memory, a different rank configuration, or a lower maximum speed, so verifying the exact HP part number is essential before fitting.

Verify HP part number and memory population rules

Confirm that your server lists one of the HP part numbers such as P07644-B21, P25203-B21, or the other referenced codes in its qualified vendor list. Also check the system's maximum supported capacity per slot, total memory limit, and any required population order for registered ECC modules.

Points forts

  • 32 GB capacity lets servers handle larger workloads
  • DDR4 3200 MHz speed accelerates data throughput
  • ECC RDIMM design corrects memory errors automatically
  • Registered 2Rx8 architecture supports dense multi-module configs
  • 2 V operation matches standard DDR4 voltage

Questions sur cet article

How can I confirm the 32GB DDR4 3200 ECC RDIMM is running at the correct 3200MHz speed and CL22 latency after installation?

Enter the system BIOS or UEFI and check the memory information screen; it should report 3200 MT/s, PC4-25600, CAS latency 22, 1.20V and registered ECC operation for the installed module.

What is included in the package and are any additional components required for installation?

The package contains one 32GB 288-pin DDR4 ECC RDIMM; no extra cables, brackets or cooling parts are needed — just an available registered DIMM slot on a compatible HP server motherboard.

Which HP part numbers does this 32GB 2Rx8 module replace so I can choose the correct version for my server?

This module is a direct replacement for HP part numbers P07644-B21, P07644-H21, P07644-K21, P11038-B21, P11445-1A1, P20502-001, P21675-001 and P25203-B21.
