32 GB DDR4 Registered DIMM

This 32 GB DDR4-2133 module is built for servers and workstations that require ECC registered memory. It targets administrators expanding capacity in HP-compatible platforms or any system accepting 288-pin RDIMMs at PC4-17000 speed. The 2Rx4 organisation and 1.20 V operation match the original HP 728629R-B21 specification. Buyers needing unbuffered UDIMMs or faster DDR4 speeds should look elsewhere.

Installation and common issues

The module installs like any standard 288-pin DDR4 RDIMM: align the notch, press firmly until the retention clips lock, then verify the new capacity in BIOS. Because it is registered ECC, the system must support registered memory; inserting it into a board that only accepts unbuffered DIMMs will prevent boot. Mixing ranks or voltages across channels can also cause training failures, so populate identical modules per channel whenever possible.

Compatibility checks before ordering

Confirm the motherboard or server documentation lists support for DDR4-2133 registered ECC RDIMMs at 1.20 V and CL15 latency. Verify the maximum capacity per slot and total system limit to ensure 32 GB modules are accepted. Check that the platform qualifies 2Rx4 organisation, as some older chipsets restrict rank configurations. Cross-reference the HP 728629R-B21 part number with your hardware vendor’s qualified-vendor list for guaranteed compatibility.

Questions about this item

How can I confirm the 32GB DDR4 2133 module is running at the rated CL15 latency after installation?

Enter the server BIOS or UEFI and verify the memory speed shows 2133 MT/s with CAS latency 15; the registered ECC design will also report corrected errors in the system event log if it is functioning correctly.

What ships with the 288-pin RDIMM and what must be sourced separately?

The box contains only the 32GB 2Rx4 1.20V registered DIMM; no heatsink, cable or software is included, and any additional DIMMs for multi-channel population must be purchased separately.

Should I choose the 32GB 2Rx4 version or a different capacity for my HP server?

Select this 32GB 2Rx4 PC4-17000 module when the service tag or maintenance manual calls for part 728629R-B21; other capacities or rank configurations will not match that specification.
