Capacity and Compatibility

This module provides 64GB of DDR5 server memory in a 2Rx4 ECC Registered RDIMM format. It is built as a direct equivalent to HPE part number P43331-B21 and carries the PC5-38400 DDR5-4800Mhz specification. The unit is designed for deployment in compatible HPE server platforms.

Intended Use Cases

This memory suits administrators upgrading or repairing HPE systems that require this exact registered ECC configuration. Buyers who need unbuffered DIMMs, non-ECC modules, or a different capacity should look at something else because this part is fixed at 64GB with registered buffering and error correction.

Deciding Specification

The registered ECC RDIMM form factor is the single attribute that determines whether this module fits the target server. Only systems designed for registered error-correcting memory can use this part.

Questions about this item

How do I install this 64GB DDR5-4800 RDIMM and what is the common mistake?

Align the notch with the slot key, press straight down until the retention clips click on both sides, and ensure the module is fully seated before tightening the chassis cover; the step often missed is verifying both clips engage.

What maintenance or replacement will this 2Rx4 ECC RDIMM need later?

No routine maintenance is required; if a correctable ECC error count rises, the module should be replaced under the lifetime warranty.

What limit appears first under sustained load with this PC5-38400 memory?

The thermal limit of the DDR5 chips is reached before the 4800 MT/s data rate throttles, so adequate case airflow is essential.
