## Long description

Memory module 16GB DDR4 2400 MHz ECC 288-pin DIMM for HP Enterprise servers is a server-grade 1x16GB DDR4 DIMM designed for use in enterprise and entry-level HPE server platforms. The module supports ECC error-correcting code to maintain data integrity in continuous-operation environments, operates at a standard 1.2 V and runs at a clock speed of 2400 MHz with CAS latency typical for this class of memory. It fits standard 288-pin DDR4 DIMM slots and is suitable for system upgrades, virtualization hosts and workloads that require reliable 24/7 operation.
Advantages
This HP Enterprise 16GB DDR4 ECC module offers error-correcting capabilities that reduce the risk of data corruption in server workloads, improving overall system stability. The module is built to HPE quality and testing standards and is validated for compatibility with supported HPE server families, which helps simplify deployment and reduce troubleshooting. Operating at 1.2 V and 2400 MHz, it delivers industry-standard performance while offering better energy efficiency compared with earlier DDR4 2133 MHz modules.
Suitable for
Server memory upgrades for HPE ML and DL Gen9 and compatible systems
Virtualization hosts and hypervisor environments
Database caching and in-memory workloads requiring ECC protection
24/7 business-critical applications and remote branch servers
Key specifications
Capacity: 16 GB
Memory type: DDR4
Form factor: 288-pin DIMM
Clock speed: 2400 MHz
Voltage: 1.2 V
Error correction: ECC (error-correcting code)
How to use
Power down the server and follow the manufacturer's safety procedures before installing the DIMM. Open the server chassis to access the memory slots, consult the server manual for correct slot population and channel balancing, and insert the 288-pin DIMM into a compatible DDR4 slot until the retention clips engage. Reassemble the server, power it on, and verify that the system firmware/BIOS recognizes the new 16GB module and that ECC is enabled where applicable. For mixed configurations, ensure matching speed and voltage specifications or allow the system to negotiate appropriate settings.
Usage recommendations
Install memory in matched pairs or according to the server manufacturer's channel population guidelines to achieve optimal performance. Use HPE-validated memory configurations for guaranteed compatibility and run firmware updates recommended by HPE to ensure correct ECC support and system stability.
