    Hi

    windows 32bit edition has a limit of around 3gb
    3.25 to be exact.

    To get the full 4g you'll need to go 64 bit I'm afraid.

    All the best

    Not strictly speaking true, but for the purposes of this discussion yes.

    You'll need a 64-bit OS to properly register the RAM and use it all.

    If it's not true strickly speaking, then what is?

    I was referring to the maximum available RAM on a 32-bit system is determined by what's left over after all the other memory registers have their slice. With 4GB being the maximum registerable value 32-bit maths can deal with, you can be left with less than 3GB when it's all sliced up.

    For example, I'm dual-booting one of our edit machines in the office with XP 32-bit for compatibility with an old Decklink video capture card. The machine has 8GB RAM in it, but it also has a 1GB Nvidia Quadro, Asus Xonar D2 and a few other bits and bobs as well. As a result XP 32-bit only reports 2.4GB total system RAM.
  5. I have had xp report anything from 3.00 to 3.49 gig. It depends on configuration.

    3Gb is the 32bit limit but i split the difference between the top two, hence 3.25

    Mathew upgrade the os to Windows 7 to get the maximize the ram you have.

    the reason windows xp some times shows more is down to the pci reserved memory range...

    Vista 32 and windows 7 utilise 4gb.
