    Hi,

    If your system is designed for accepting DDR (Double Data Rate) memories of 184pin DIMM (usually desktops) or 200pin SODIMM (usually laptops) built, for your system to fully recognize 1GB capacity per memory slot, you need to use 'Low Density - 64Mx8 config' 1GB module. If you use 'High-Density - 128Mx4 config' 1GB module, your PC may only recognize it as HALF the size at 512MB or most of the time it will not work.

    In summary:-

    • LOW DENSITY modules have 100% compatibility with ALL systems and ALL chipsets as it fully follows JEDEC guidelines.
    • HIGH DENSITY modules only have 10% compatibility and are VERY SLOW as it breaks all JEDEC  (Joint Electron Devices Engineering) Council guideline

    I would also suggest you to contact IBM support center and check.
