## Summary description

HP Enterprise P07642-B21 is a 16 GB server memory module (1 x 16 GB) in 288-pin DIMM format. It uses DDR4 technology at 3200 MHz with ECC support and CAS latency 22, designed for internal server memory expansion and reliable error-correcting operation in enterprise-class systems.

## Long description

HP Enterprise P07642-B21 is a 16 GB server memory module (1 x 16 GB) in a 288-pin DIMM form factor. It uses DDR4 technology at 3200 MHz with ECC support and CAS latency CL22, designed for internal server memory expansion and error-correcting operation in enterprise-class systems. The module is intended for use in HPE server platforms and follows HPE SmartMemory qualification standards to ensure compatibility, signal integrity and consistent performance under server workloads.
Advantages
This module provides higher bandwidth and improved latency at 3200 MT/s compared with lower-speed DDR4 parts, while ECC support helps detect and correct single-bit memory errors to improve system reliability. HPE SmartMemory qualification ensures compatibility with supported HPE server platforms, reducing the likelihood of incompatibility issues and unnecessary DIMM replacement. The module is built from selected DRAM components and undergoes HPE testing and validation for stable operation in virtualized, database and cloud workloads.
Suitable for
 Expanding memory capacity in HPE enterprise and SMB servers
 Database servers and applications with moderate to high memory demands
 Virtualized server environments and cloud infrastructure
 Systems that require ECC protection to maintain uptime and data integrity
Key specifications
 Capacity: 16 GB (single module)
 Memory type: DDR4
 Speed: 3200 MT/s (commonly referenced as DDR4-3200)
 Form factor: 288-pin DIMM
 ECC: Error-correcting code support
 CAS latency: CL22
How to use
Install the module into an empty compatible 288-pin DIMM slot on a supported HPE server motherboard following the server vendor's service manual and safety procedures. Power down the server and disconnect power before installing or removing memory modules unless hot-swap/online replacement is explicitly supported by the specific platform. Align the module with the slot notch, insert evenly until the module latches, then reconnect power and verify system POST and BIOS/UEFI memory reporting to confirm that the module is recognized and operating at the expected speed and ECC mode.
Usage recommendations
For optimal results, populate memory channels according to the server platform's recommended channel and slot population rules, use matched modules for multi-module configurations, and verify firmware/BIOS compatibility and settings to enable the full 3200 MT/s speed and ECC functionality. Regularly update server firmware and monitor memory health via server management tools to maintain reliability.
