## Long description

Battery-backed DDR memory module 40-bit 64MB for HP systems (MPN: 305416-001-RFB, EAN: 5712505610756) is a compact, board-mounted DDR SDRAM module with integrated backup battery designed to preserve volatile data when main power is lost. With a 40-bit data path and 64 MB capacity, this module is intended for HP server and embedded platforms that require short-term non-volatile storage for cached data, configuration settings, or write buffers. The module fits specified HP system sockets and follows form-factor and electrical characteristics compatible with targeted controller boards and RAID or embedded controller designs.
Advantages
This battery-backed DDR module provides immediate data retention during power interruptions through an on-board backup battery, minimizing data loss for critical cached writes. The 40-bit data width supports parity or ECC arrangements used by compatible HP controllers to maintain data integrity. Its 64 MB capacity is suitable for temporary storage needs without requiring external power supplies or complex supercapacitor arrangements. The module is field-replaceable and designed to match HP system mechanical and electrical interfaces for straightforward swapping and maintenance.
Suitable for
HP RAID controllers and cache modules requiring short-term non-volatile RAM

How to use
Before installation, power down the host system and follow HP service instructions for safe module replacement. Handle the module using electrostatic discharge (ESD) precautions and align the module with the designated socket on the controller or system board. Press into place until the module is seated and secured according to the system’s retention mechanism. After installation, power on the system and verify that the controller’s firmware recognizes the module; check system logs or management interfaces for battery-backed memory status. Replace the module or battery according to HP service intervals or when the controller reports reduced retention capability.
Usage recommendations
Store and operate the module within the host manufacturer’s specified temperature and humidity ranges. Use genuine HP replacement parts (MPN 305416-001-RFB) to ensure compatibility. When disposing of the module, follow local regulations for electronic waste and battery-containing devices. For best results, consult HP service documentation for battery-backed memory handling, replacement intervals, and firmware procedures to ensure continued data protection in the target HP systems.
