Why choose it

Built as HPE SmartMemory, this module is tuned for maximum performance and reliability on ProLiant platforms. ECC detects and corrects single-bit errors, preventing silent data corruption in critical applications. Dual-rank architecture boosts memory bandwidth, while the low 1.2V voltage reduces power draw and cooling costs. It’s a drop-in upgrade that extends the life of existing servers.

Ideal use cases

• Virtualization: VMware, Hyper-V, KVM with high VM density
• Database servers: SQL, Oracle, PostgreSQL with large in-memory datasets
• In-memory computing: SAP HANA, Redis, Memcached
• High-performance computing: simulations, analytics, rendering
• Enterprise applications: ERP, CRM, collaboration suites

Good to know

Always verify compatibility with your specific ProLiant model and processor generation. Mixing with non-HPE memory may disable SmartMemory features. Installation requires anti-static precautions and matching of rank and speed across channels for optimal performance.
