Hewlett Packard Enterprise HPE - DDR4 - module - 32GB - DIMM 288-PIN - 2133 MHz / PC4-17000 - CL15 registered - ECC (728629-B21)

The HPE 32GB DDR4-2133 ECC Registered memory module (1x32GB, dual-rank, x4) is designed for HP ProLiant Gen9 servers and other compatible systems requiring 288-pin DIMM DDR4 memory. With a clock speed of 2133 MHz, 1.2 V operating voltage and ECC registered design, this module provides higher capacity and platform-validated reliability for virtualization, database and high-performance workloads in data center environments.

Advantages

HP SmartMemory for ProLiant Gen9 servers verifies that installed memory has passed HP qualification and testing, enabling platform-specific performance tuning and some ROM-enabled memory features. Compared with previous generations and many third-party alternatives, this DDR4 module offers lower power consumption (1.2 V operation and up to 37% lower power vs DDR3 at the same speed), improved performance in rack/tower and blade systems, and integration with HP OneView for predictive fault notifications when supported.

Suitable for

• HP ProLiant Gen9 servers and compatible DDR4 288-pin DIMM systems
• Virtualized server environments and cloud infrastructure
• Large databases, high-performance computing and multi-threaded workloads
• Systems requiring ECC Registered memory for data integrity

How to use

Power down the server, follow the manufacturer’s service manual to access the memory slots, and install the 288-pin RDIMM module into an appropriate DIMM slot following the server’s population rules for dual-rank modules. Ensure the module is fully seated and the retention clips are locked. After installation, power on the system and check firmware/ROM settings to confirm the memory is recognized and any HP SmartMemory features or performance profiles are enabled if available.

Recommendations

Use this HPE 32GB DDR4-2133 ECC Registered module in matched configurations (identical speed, rank and timing) across populated channels for optimal performance and stability. When used with HP OneView and supported Gen9 server firmware, enable monitoring and predictive fault detection to reduce memory-related outages.
