## Summary description

The HP 398707-051 memory module offers 2 GB of DDR2 RAM with a clock speed of 667 MHz. Designed for PC and server use, this 240-pin DIMM module features ECC for error correction, ensuring data integrity. With a CAS latency of 5, it provides reliable performance for various applications.

## Long description

The HP 398707-051 memory module provides 2 GB of DDR2 system memory operating at 667 MHz. This 240-pin DIMM is equipped with ECC (error-correcting code) to detect and correct single-bit memory errors, supporting data integrity in compatible PCs and servers. With a CAS latency of 5 and a 1.5 V operating voltage, the module is intended for systems that accept DDR2 240-pin ECC DIMMs and requires proper motherboard and BIOS support for ECC functionality.
Advantages
The module’s ECC capability improves reliability by reducing the risk of data corruption in environments where memory integrity matters. The 667 MHz clock speed and CL5 timing deliver predictable performance for legacy platforms that rely on DDR2 memory. The standard 240-pin DIMM form factor ensures compatibility with many desktop and server motherboards designed for DDR2 ECC modules, and the 1.5 V rating matches the electrical requirements of typical DDR2 memory slots.
Suitable for
 Legacy servers and workstations that require ECC DDR2 memory
 Systems needing 2 GB DIMMs to expand existing DDR2 configurations
 Environments prioritizing data integrity over high-frequency memory
Key specifications
 Brand: HP Enterprise
 Manufacturer part number (MPN): 398707-051-RFB
 EAN: 5711045792182
 Capacity: 2 GB
 Memory type: DDR2
 Form factor: 240-pin DIMM
 Clock speed: 667 MHz
 CAS latency: 5
 ECC: Yes (error-correcting code)
 Voltage: 1.5 V
How to use
Power off the system and disconnect it from mains before installing the DIMM. Consult the motherboard or server manual to identify the correct memory slots and any channel/population rules. Align the module’s notch with the slot key, insert the 240-pin DIMM evenly until the retention clips engage, and verify that the module is fully seated. After installation, power on the system and check BIOS/UEFI settings to confirm that the memory is recognized and that ECC is enabled if required by the platform.
Usage recommendations
Ensure motherboard and BIOS compatibility with DDR2 ECC 240-pin DIMMs and verify maximum supported memory capacity per slot and channel. When mixing modules, use identical specifications (capacity, speed, ECC support) to maintain stability. For systems that rely on ECC for fault tolerance, enable ECC in BIOS/UEFI and perform memory diagnostics after installation.
