P06033-B21 - HPE 32GB DDR4 Server Memory

HPE P06033-B21 — 32GB (1×32GB) DDR4-3200 Registered Smart Memory Kit (2Rx4, CAS 22)

What it is

P06033-B21 is an HPE Smart Memory Registered (RDIMM) module designed for HPE ProLiant servers that support DDR4-3200 RDIMM memory. It comes as a single 32 GB stick with error-correcting code (ECC) and is built to HPE’s server-grade specifications for reliability and compatibility.

Why buyers pick P06033-B21 (plain English)

Enterprise-grade reliability: ECC detects and corrects memory errors, which boosts uptime and protects data integrity.

Registered buffering: RDIMM improves signal stability and enables higher total memory capacities in servers compared to unbuffered modules.

Right balance of capacity and performance: 32 GB is a common building block for virtualization hosts, database servers, and general compute workloads.

HPE Smart Memory: Ensures proper voltage/timing/firmware compatibility with ProLiant systems, minimizing incompatibility issues.
