IBM 39M5790 PC2-5300F 667MHz DDR2 2Rx4 FBDIMM ECC Server Memory 38L5905

Overview
IBM part number 39M5790, also known as PC2-5300F 667MHz DDR2 2Rx4 FBDIMM ECC Server Memory (38L5905), delivers reliable, high-performance memory for mission critical servers. This fully buffered DIMM (FBDIMM) is engineered to support large memory capacities while maintaining error correction (ECC) to protect data integrity in demanding data-center environments.

Key Features

• 667 MHz data rate (PC2-5300) for fast data access
• ECC (error correcting code) to detect and correct single-bit errors
• Fully buffered design reduces electrical load on the memory controller
• 2Rx4 organization provides a balanced mix of capacity and performance
• Compatible with IBM System x and other platforms that support DDR2 FBDIMM
• Low power consumption for efficient operation in dense server racks
