1. Description
This Hynix unbuffered Dual In-Line Memory Module(DIMM) series consists of 1Gb Z version. DDR3 SDRAMs in Fine Ball
Grid Array(FBGA) packages on a 240 pin glass-epoxy substrate. This DDR3 Unbuffered DIMM series based on 1Gb Z
ver. provide a high performance 8 byte interface in 133.35mm width form factor of industry standard. It is suitble for
easy interchange and addition.
