FAQ's
What systems are compatible with the 405476-551 memory module? This memory module is compatible with HP servers and workstations that support 2GB DDR2-667 PC2-5300 ECC Registered 240-pin RDIMMs. Compatibility depends on the motherboard memory slot specifications and chipset support. What does ECC Registered mean on this memory? ECC Registered indicates the module includes error-correcting code (ECC) to detect and correct memory errors and is registered (buffered) to improve signal integrity in larger memory configurations. Can this module replace non-ECC or unbuffered memory? No, ECC Registered memory requires motherboard and chipset support. It cannot directly replace non-ECC or unbuffered memory modules without compatibility issues. What is the significance of the 240-pin form factor? The 240-pin design specifies the physical connector and slot type for DDR2 RDIMM modules. This module fits standard 240-pin DDR2 memory slots on compatible HP hardware. Is this memory suitable for desktop PCs? This module is intended primarily for servers and workstations supporting ECC Registered DDR2 memory; it is generally not compatible with standard desktop PCs that use unbuffered non-ECC modules. Does this module support dual-channel memory configurations? Dual-channel support depends on the motherboard and system architecture. The module itself supports DDR2-667 speeds and can operate in dual-channel mode if supported by the system.
