Detailed Specifications
HP 466440-B21 - Server Memory Kit PC2-5300 FBD
Overview :
The HP 466440-B21 is a server-grade memory kit designed for enterprise systems using fully buffered DIMMs. It is typically deployed by infrastructure engineers who need reliable ECC memory in dual-module kits, and it addresses the need to upgrade existing systems with matched memory pairs for interleaving and redundancy. This kit comprises two 4 GB modules operating at DDR2-667 MHz (PC2-5300) and supports error correction to maintain data integrity in 24×7 server environments. It is intended for deployment in data centres, blade servers or rackmount systems - such as HP ProLiant blades or enterprise tower servers - where memory density and system compatibility matter. Integration is straightforward in HP platforms that support FB-DIMM memory, and it works within the broader HP server memory architecture to align with existing bank-population and interleaving rules.
Key Features :
Two 4 GB fully buffered DIMMs in one kit
DDR2-667 MHz (PC2-5300) memory speed
ECC support for error correction in server environments
Low-power dual-rank configuration (1.8 V)
240-pin FB-DIMM form-factor for HP server compatibility
