Memory Module HPE DDR3 32GB 1333MHz ECC

The HPE 647903-B21 Memory Module HPE DDR3 32GB 1333MHz ECC provides 32 GB of DDR3 ECC RAM at 1333 MHz and CAS latency 9, designed for HP ProLiant servers. This module is intended to improve server memory capacity and stability for enterprise workloads while supporting error correction to maintain data integrity. It is compatible with HP SmartMemory functionality introduced for ProLiant Gen8 systems, enabling qualification and authentication features when used in supported HP servers.

Advantages

This HPE DDR3 32GB 1333MHz ECC module delivers higher memory capacity and ECC reliability required for virtualization, large databases and high-performance computing. The module’s ECC support helps detect and correct single-bit memory errors, reducing the risk of data corruption. When installed in HP ProLiant Gen8 systems, HP SmartMemory authentication allows the system to verify that the module has passed HP qualification and to enable extended memory performance features via the system ROM.

Suitable for

• Enterprise servers running HP ProLiant Gen8 and compatible models
• Virtualized environments and hypervisors
• Large database and transactional applications
• High-performance computing and data center workloads
