The HPE 64GB Registered Smart Memory Kit is a high-capacity, server-grade memory designed for HPE ProLiant environments that need strong performance, stability, and predictable compatibility. Using DDR5-5600 RDIMM technology, it supports higher bandwidth and better efficiency for modern compute workloads while maintaining the reliability expected in enterprise server platforms.

This kit excels in situations where you’re maximising memory per host—such as dense virtualisation, large in-memory databases, analytics, and application servers with heavy concurrency. The 64GB module size is ideal when you want to increase overall capacity while keeping DIMM slots available for future expansion, helping you scale without immediately filling every channel.
