## Long description

The HPE 32GB DDR4-2133 288-pin DIMM is a registered memory module designed for HPE ProLiant Gen9 servers and similar server-class systems. This 1x32GB, dual-rank x4 DDR4 module operates at 2133 MHz with 1.2 V and supports ECC to help maintain data integrity in demanding data center and virtualization environments. HP SmartMemory technology allows ProLiant Gen9 systems to authenticate the module, enabling platform-specific tuning and extended memory features through the system ROM.
Advantages
HP SmartMemory for Gen9 servers provides validated compatibility and platform-level testing that ensures reliable operation and optimized performance in HPE systems. The DDR4 design reduces power consumption compared with DDR3, offers higher capacity per module, and supports features such as fault prediction when used with management tools like HPE OneView. Registered (RDIMM) configuration supports larger memory configurations and increased system stability.
Suitable for
 HPE ProLiant Gen9 rack and tower servers
 Server virtualization and cloud infrastructure
 Large database and high-performance computing workloads
 Systems requiring ECC registered (RDIMM) memory
