HPE 64GB DDR4-3200 ECC Registered DIMM geheugenmodule (P11446-1A1)

Data center administrators running HPE ProLiant servers often face memory bottlenecks when virtualizing multiple workloads or running in-memory databases. This 64GB DDR4-3200 ECC Registered DIMM (R-DIMM) from HPE directly addresses that challenge, delivering high capacity, speed, and reliability for demanding enterprise applications. With error-correcting code (ECC) and registered architecture, it ensures data integrity and stable operation even under heavy load, making it a trusted upgrade for mission-critical environments.

Why choose it

This module is engineered for server environments where uptime and data accuracy are non-negotiable. ECC technology detects and corrects single-bit memory errors, preventing silent data corruption. The registered design buffers command and address signals, allowing greater memory scalability across multiple DIMMs per channel—ideal for high-density server configurations. With a 3200 MHz transfer rate, it provides the bandwidth needed for virtualization, database management, and compute-intensive tasks.

Ideal use cases

• Virtualization hosts running VMware, Hyper-V, or KVM
• Enterprise databases (SQL, Oracle, SAP HANA)
• High-performance computing (HPC) clusters
• Memory-intensive analytics and AI/ML workloads
• Upgrading existing HPE ProLiant servers to maximum capacity

Good to know

This is a genuine HPE Smart Memory module, validated for compatibility with a wide range of ProLiant Gen10 and Gen11 servers. It operates at a standard 1.2 V for energy efficiency and meets JEDEC specifications. The dual-rank design offers a balance between capacity and performance, and the CL22 latency is optimized for server workloads. Always verify your server's memory configuration guidelines to ensure proper population order and maximum performance.
