HP - DDR3 - module - 8 GB - DIMM 240-PIN - 1600MHz / PC3-12800 CL11 registered ECC

The HPE 647899-B21 Memory Module HPE DDR3 8GB 1600MHz ECC provides 8 GB of DDR3 system memory at 1600 MHz in a 240-pin DIMM designed for HP ProLiant servers and compatible PCs. This HP Enterprise module includes ECC support and is engineered to meet server-class reliability and stability requirements. It is compatible with ProLiant Gen8 platforms and uses HP SmartMemory technology for validated performance and system-level features.

Advantages

HP SmartMemory verification enables the server to identify and authenticate the module, allowing extended memory performance features on supported ProLiant Gen8 systems. ECC support improves data integrity by detecting and correcting single-bit memory errors, while the 1600 MHz clock and CAS latency 11 balance performance and compatibility. The 240-pin DIMM form factor and standard 1.5 V operation make this module suitable for a wide range of legacy DDR3 server configurations.

Suitable for

• HP ProLiant Gen8 servers requiring validated HP memory
• Server and workstation upgrades that need ECC memory for stability
• Virtualized environments and database servers where memory reliability is important
