HPE DDR4 2933 32GB ECC RDIMM

This 32GB DDR4 2933 registered DIMM provides error-correcting code memory for HPE servers and workstations. It operates at 1.20V with CL21 latency and a 1Rx4 organisation. The 288-pin module uses major-brand DRAM chips and is validated for the HPE P38448-B21 part number.

Suited for HPE server upgrades needing registered

This module fits administrators expanding memory in compatible HPE platforms that require registered ECC RDIMMs at DDR4 2933 speed. It is not for systems that accept only unbuffered UDIMMs, for builds needing a lower or higher data rate, or for configurations that cannot address a 32GB single rank.

Deciding specification — 1Rx4 registered ECC

The single rank 1Rx4 registered ECC design at DDR4 2933 determines whether the memory controller can populate the slot without exceeding rank limits. Verify that your HPE system supports 1Rx4 registered modules at this speed before purchase.

Questions about this item

Will the 288-pin DDR4 RDIMM fit my HPE server DIMM slots?

The module uses the standard 288-pin DDR4 RDIMM form factor and is built for HPE systems that accept PC4-23400 registered ECC memory.

What is the correct seating procedure for this 1Rx4 registered DIMM?

Align the key notch with the slot, press straight down until both retention clips click, and verify the module sits evenly — the most common error is stopping before the clips fully engage.

How long will the Samsung, Micron or Hynix DRAM chips last under continuous server workloads?

The major OEM chips are stress-tested under load and covered by a lifetime replacement warranty, so no scheduled replacement is expected.
