32GB DDR4-2933 ECC RDIMM for HP Servers

This 32GB DDR4-2933 1Rx4 ECC Registered RDIMM is built as an HP-compatible equivalent to part number P38446-K21. It targets administrators upgrading or repairing supported HP ProLiant and Apollo platforms that require registered ECC memory at 1.20V.

Installation notes and common issues

The module installs like any standard RDIMM: align the notch, seat it firmly until the ejector clips lock, and ensure the server BIOS is current. Failures usually stem from mixing registered and unbuffered DIMMs, exceeding the platform's rank-per-channel limit, or populating slots in an unsupported sequence.

Pre-order checklist

Verify that your server model lists P38446-K21 or a 32GB PC4-23400 1Rx4 registered ECC part in its qualified vendor list. Confirm the maximum supported capacity per socket and the allowed population rules for the target generation. Ensure the operating voltage matches the 1.20V specification.
