☑️ Key Features

• 2GB Individual Module: Suitable for replacing a corresponding module or expanding a supported memory configuration.
• ECC Protection: Provides error-correcting memory functionality in compatible systems.
• Registered Architecture: Designed for server and workstation platforms requiring registered DDR2 DIMMs.
• Dual-Rank 2Rx4 Organization: Matches supported configurations using dual-rank modules built with x4 memory devices.
• DDR2-667 Performance: Supports operation at up to 667 MT/s, subject to the installed processor and memory configuration.
• Address/Command Parity: Supports parity checking on compatible registered-memory platforms.

⚙️ Fit Notes

• Single-module sale: Each quantity ordered includes one 2GB module.
• Memory type must match: Requires support for DDR2 ECC Registered DIMMs. This module is not interchangeable with DDR2 unbuffered memory or fully buffered FB-DIMMs.
• Matched population requirements: Many compatible systems require matched pairs or larger groups. The xw9400 requires matched pairs; the PowerEdge R805 requires matched groups of four. Purchase the quantity needed to complete the required configuration.
• Processor-specific support: DL165 G5 and DL185 G5 compatibility applies to configurations supporting PC2-5300 dual-rank memory. For the DL365 G5, the listed dual-rank DDR2-667 option is documented for Opteron 2352, 2354, and 2356 processors.
• Rank and organization: Match capacity, speed, rank, and device organization within each required memory pair or bank.
• Slot availability: On multiprocessor systems, some memory slots require the corresponding processor to be installed.
• Operating speed: Actual memory speed depends on the processor, BIOS, installed modules, and memory population.
