IBM 38L5903 server / storage / networking hardware Server Hardware / Parts

The IBM 38L5903 is a 1GB PC2-5300F (DDR2-667) fully buffered ECC memory DIMM, 2Rx8 rank, 240-pin, running at 1.8V. It is cross-referenced under the related part numbers 39M5785, 44E5033 and 44E3540, and is a standard memory upgrade/replacement module for IBM System x servers of the DDR2 generation, including the x3650 family. Fully buffered ECC DIMMs of this type were the standard memory technology across IBM’s mid-2000s System x range, and genuine modules remain a routine requirement for restoring full memory capacity or capacity expansion on machines that are still in productive service. Confirm the exact server model and memory configuration before ordering, since fully buffered DIMMs are typically installed in matched sets. IBM System x hardware of this generation remains in active use across many established deployments. Tech-Star (UK-based, shipped worldwide) stocks IBM System x memory.
