☑️ Key Features

• ECC memory support: Enables memory error detection and correction in systems that support and activate ECC.
• DDR2-800 performance: Provides an 800 MT/s speed rating for supported platforms.
• Standard 240-pin construction: Fits the full-size DDR2 ECC UDIMM sockets used by the listed systems.
• 1GB replacement capacity: Useful for restoring an existing configuration or adding capacity in supported increments.
• Multiple replacement references: Covers matching manufacturer modules and OEM service, assembly and option numbers.
• Automatic memory configuration: The system reads the module’s SPD information to select supported operating settings.
• Legacy equipment support: Helps maintain compatible servers, workstations and custom systems built around the listed motherboards.

Applications and Use Cases

• Server maintenance: Replace failed memory in supported rack and tower servers.
• Workstation repairs: Restore memory capacity in compatible engineering, office and technical workstations.
• Storage systems: Maintain supported file-server and network-storage configurations.
• Memory expansion: Add 1GB modules where the platform’s capacity limits and population rules allow.
• Custom server builds: Install in supported Supermicro, Intel, ASUS, TYAN and Gigabyte motherboards.
• Repair benches and spare inventory: Keep matching ECC UDIMMs available for servicing multiple legacy platforms.
• Training and test environments: Maintain compatible hardware used for operating-system testing, hardware diagnostics and technical instruction.

⚙️ Fit Notes

• Match the complete memory type: The system must support DDR2 ECC unbuffered UDIMMs. Pin count and capacity alone do not establish compatibility.
• Buffering matters: Registered RDIMMs and fully buffered FB-DIMMs are different memory types and cannot be substituted for this module.
• Rank may vary: The replacement references include both single-rank and dual-rank designs. When adding memory to an existing bank, follow the manufacturer’s requirements for matching capacity, rank and organization.
• Observe matched-pair requirements: Install modules in the designated sockets and use matching modules where required for dual-channel operation or supported population.
• Operating speed depends on the system: Some listed platforms operate memory below 800 MT/s. A supported DDR2-800 replacement runs at the speed selected by the processor, chipset and BIOS.
• xw4600 population: Follow the workstation’s supported one-, two- or four-DIMM configurations; three-DIMM configurations are not supported.
• PowerVault NF100 population: Install memory in supported two- or four-module configurations using matching module capacities.
• ECC operation depends on the platform: The motherboard, processor and BIOS must support ECC. Do not mix ECC and non-ECC modules.
• Capacity limits still apply: Check the system’s maximum memory capacity and supported capacity per slot before adding modules.
• Exact matching requests: If a particular part number or rank is required, specify it in the order notes.
