HP 405477-061 Registered ECC DDR2 667 Server Memory Module

HP 405477-061 – 4GB PC2-5300R Server Memory Module

Overview :

The HP 405477-061 is a 4 GB DDR2-667 (PC2-5300) ECC registered memory module designed for enterprise servers and blade systems. Engineers specify it when upgrading or maintaining legacy server platforms that require registered server-class DIMMs with error-correcting capability. It supports dual-rank x4 architecture and operates at 1.8 V (or 1.5 V in some listings) consistent with server memory standards. This module is broadly compatible with platforms in the HP ProLiant DL and BL series, especially G5 and earlier generations. In a data-center context it fits in rack or blade server memory sockets. It integrates with HP’s server firmware and memory calibration processes and will appear alongside other registered ECC DIMMs under HP memory preference listings.

Key Features :

• 4 GB capacity in a single 240-pin DIMM format

• DDR2-667 speed (PC2-5300) rated for high-end server use

• ECC Registered design for error detection and system stability

• Dual-rank x4 configuration optimised for server memory channels

• 1.8 V (or 1.5 V variant) voltage specification for legacy HP systems
