HPE 32GB Dual Rank x8 DDR5-4800 EC8 Registered Smart Memory Module

The HPE P43328-B21 is a server memory module that adds 32 GB of DDR5 capacity to compatible HPE systems. By running at 4800 MT/s, it delivers the extra bandwidth that modern virtualization hosts, database engines, and cloud applications demand without forcing a system overhaul.

This module uses a dual-rank architecture built on x8 devices, so data moves smoothly even when workloads push the memory controller to its limits. Registered signaling and built-in ECC continuously check and correct bit errors, keeping virtual machines stable and protecting critical transactions from silent corruption.

Because it draws only 1.1 V, the module helps lower thermal output and reduces power costs across dense server racks. Each unit ships as part of the HPE Smart Memory line, meaning firmware and hardware have been validated together for true plug-and-play recognition in HPE servers. Installation is straightforward: seat the 288-pin DIMM in an open DDR5 slot, power up, and the additional capacity is ready to use.

Whether you manage a small cluster that runs containerized microservices or a high-traffic database farm, this module offers a simple path to higher concurrency, faster response times, and more room for growth.
