Memory module HP SPS-BD MEM 256M 72BT DDR with battery backup, 256 MB, 72-bit ECC

HP SPS-BD MEM 256M 72BT DDR with battery backup, 256 MB, 72-bit ECC is a compact server memory module designed for compatible HP servers and storage controllers. The module provides a 72-bit data path with ECC support and DDR technology to maintain data integrity and improve stability. Integrated battery backup preserves cached write data during temporary power interruptions, reducing the risk of data loss in enterprise environments.

Advantages

This 256 MB HP memory module offers ECC (error-correcting code) across a 72-bit data path to detect and correct single-bit memory errors and help prevent data corruption. The DDR technology provides synchronous data transfer suitable for legacy systems that require DDR modules. The built-in battery backup function maintains cached data when power is interrupted, enabling safe write-back operations and improving overall system reliability. The module is designed to meet HP compatibility specifications and is identified by MPN 309522-001-RFB and EAN 5711045912207.

Suitable for

• HP servers and storage controllers that accept 72-bit ECC DDR memory modules
• Enterprise storage systems requiring battery-backed cache for write protection
• Legacy DDR-based systems needing small-capacity ECC memory upgrades

How to use

Install the memory module into a compatible memory slot following the server or storage controller manufacturer's installation instructions and ESD safety procedures. Ensure the system is powered down and unplugged before insertion unless the server supports hot-plug memory replacement. After installation, verify the module is recognized in system firmware or hardware management utilities and confirm that battery backup status is reported as healthy. Configure the server or controller cache settings according to vendor guidelines to enable battery-backed write caching if applicable.

Usage recommendations

Use this HP 256 MB 72-bit ECC DDR module only in systems explicitly listed as compatible by HP. Periodically check battery backup health through system management tools and replace the battery or module according to HP maintenance recommendations to ensure continued protection of cached data. When upgrading or replacing memory, match ECC type and data width (72-bit) to maintain system stability.
