P64707-B21 - HPE 64GB 2Rx8 DDR5-5600 Server Memory

HPE P64707-B21 — 64GB 2Rx8 DDR5-5600 Server Memory

What it is

P64707-B21 is an HPE server memory module designed for HPE ProLiant and select HPE Synergy systems that support DDR5.
It’s a 64 GB DDR5 UDIMM (Unbuffered DIMM) rated at 5600 MT/s, built to deliver higher performance and efficiency for mainstream enterprise workloads, virtualization, and memory-intensive applications.

Why buyers pick P64707-B21 (plain English)

High capacity & speed
64 GB of DDR5 memory at 5600 MT/s gives you plenty of space and bandwidth for multitasking, virtualization, and data-intensive applications — boosting performance compared with older DDR4 modules.

Modern memory technology
DDR5 improves performance, efficiency, and reliability over earlier generations with features like higher speeds, improved channel efficiency, and on-die ECC.

Optimized for HPE servers
Validated and qualified by HPE for predictable compatibility and stability with supported ProLiant platforms.

Scales with your needs
64 GB per DIMM lets you build large memory configurations without overfilling slots — great for virtualization hosts and database servers.

Where it fits (and when to choose something else)

Perfect for:

• HPE ProLiant servers with DDR5 support

• Virtualization and hyperconverged platforms

• Memory-intensive enterprise applications

• Balanced capacity and performance builds

Choose something else if:

• You need higher capacity per DIMM → 128 GB or 256 GB DDR5 modules

• You’re on older platforms lacking DDR5 support → DDR4 memory

• You want registered/buffered modules → RDIMM/LR-DIMM (for supported systems)

TL;DR

P64707-B21 is HPE’s 64 GB DDR5-5600 server memory module:
a high-performance, high-capacity DIMM designed for enterprise servers needing responsive, efficient memory for virtualization and demanding workloads.
