HP 805347-B21 8GB DDR4-2400 ECC Registered DIMM Memory Module

Data centers and enterprise IT departments running HP ProLiant Gen9 servers often need to expand memory capacity without compromising stability. The HP 805347-B21 8GB DDR4-2400 ECC Registered DIMM is engineered for exactly that scenario—delivering reliable performance for virtualization, database workloads, and memory-intensive applications.

Key specifications

• Capacity: 8 GB
• Memory type: DDR4 SDRAM
• Speed: 2400 MHz (PC4-19200)
• CAS latency: CL17
• Voltage: 1.2 V
• Form factor: 288-pin DIMM
• Error correction: ECC
• Buffering: Registered (RDIMM)
• Rank: Single rank
• Chip organization: x8

Why choose it

This module reduces the risk of data corruption with ECC technology, while registered buffering improves signal integrity in high-density server configurations. Its 2400 MHz speed balances performance and power efficiency, and the 1.2 V operating voltage lowers energy consumption compared to older DDR3 modules.

Ideal use cases

• HP ProLiant Gen9 server memory upgrades
• Virtualized environments (VMware, Hyper-V)
• Database servers and business-critical applications
• Memory-intensive computing and caching

Good to know

Compatible with a wide range of HP ProLiant servers that support DDR4 ECC registered DIMMs. Always verify your server's memory configuration rules before installation. The module is single rank, which can be advantageous for achieving higher memory speeds in certain configurations.
