HPE Server ECC RDIMM Upgrade

This 32GB DDR4 2933MHz CL21 registered DIMM is built for HPE systems requiring ECC error correction. It targets IT administrators expanding memory in compatible HPE servers and workstations where data integrity and stability are mandatory. Buyers needing unbuffered UDIMM modules or non-ECC memory for consumer platforms cannot use this product.

Thermals Power and Noise

The module operates at a standard 1.2V without a heat spreader, relying on server chassis airflow for cooling. Registered buffering and ECC logic add minimal power draw over unbuffered equivalents. No moving parts are present so the module itself produces no audible noise in normal operation.

Included Module Only

The package contains a single 32GB 288-pin RDIMM tested for compatibility with HPE part number P28225-B21. No additional brackets, cables or software utilities are bundled. Installation follows the server manufacturer’s documented memory population rules.

Questions about this item

How do I install this 288-pin DDR4 RDIMM in an HPE server, and which step is often missed?

Align the notch on the 288-pin module with the slot key, press firmly until both retention clips click, then verify in BIOS that the 2933 MHz speed and ECC registered mode are detected.

What maintenance or replacement will this 32 GB ECC RDIMM need over time?

No scheduled maintenance is required; ECC corrects single-bit errors on the fly, and the module should only be replaced if the server logs uncorrectable memory errors or a DIMM failure alert.

What limit appears first when this CL21 1.2 V module runs sustained workloads?

The CAS latency of 21 cycles at 2933 MHz sets the access timing ceiling, so sustained throughput is bounded by that latency figure rather than the 1.2 V power envelope.
