## Summary description

The HPE 805358-B21 is a 64 GB DDR4 memory module designed for PCs and servers. It features a 2400 MHz clock speed, 288-pin DIMM form factor, and ECC for error correction. With a CAS latency of 17, this module ensures reliable performance and stability, making it ideal for demanding applications and workloads.

## Long description

The HPE 805358-B21 64 GB DDR4 2400 MHz ECC is a registered DIMM memory module designed for use in enterprise and SMB servers as well as compatible workstation platforms. With 64 GB capacity, DDR4 technology and ECC error-correction, this module is intended to deliver stable, high-capacity system memory for virtualized environments, databases and other memory-intensive workloads. The module uses a 288-pin DIMM form factor, operates at a nominal 1.2 V and provides a CAS latency of 17 at 2400 MHz clock speed.
Advantages
This HPE memory module combines high capacity and error-correcting DDR4 technology to reduce risk of data corruption and improve system uptime. Registered ECC design helps maintain signal integrity in multi-module server configurations while allowing large memory pools. The 2400 MHz speed balances throughput and broad platform compatibility, and the 1.2 V operating voltage contributes to efficient power use in densely populated server systems. The module is qualified for HPE servers to ensure interoperability and predictable behavior under load.
Suitable for
 Enterprise servers running virtualization and consolidation workloads
 Database servers and in-memory processing systems
 High-availability and fault-tolerant systems requiring ECC protection
 Workstations and compute nodes that accept 288-pin registered DDR4 DIMMs
Key specifications
 Memory capacity: 64 GB
 Memory type: DDR4 ECC (registered)
 Clock speed: 2400 MHz
 CAS latency: 17
 Form factor: 288-pin DIMM
 Operating voltage: 1.2 V
How to use
Install the module in a compatible server or workstation motherboard that supports registered DDR4 ECC 288-pin DIMMs. Before installation, power down the system and disconnect power. Observe electrostatic discharge (ESD) precautions and consult the server or motherboard manual for correct DIMM slot population and channel configuration to enable optimal performance. After seating the module in the slot and securing the retention clips, reconnect power and verify that the system recognizes the full installed capacity in firmware or the operating system.
Usage recommendations
For best stability and performance, populate memory in matched pairs or according to the server vendor's recommended channel population rules. Use HPE-qualified DIMM combinations and firmware revisions to ensure compatibility and to take advantage of platform-specific memory features. Monitor system event logs and employ ECC reporting tools to identify and respond to any memory errors promptly.
