    32 bit OS only uses 3.25gb of address space.
    you need to install ubuntu 64,xp 64,or vista 64 bit for use full 4gb ram

    Wrong mate!
    32bit OSes can address 4GB , but some of it's addresses are reserved for Peripherals such as VGA likewise.. so if u wanna use the full 4GB ram u gotta use a 64bit OS and enable Memory remapping feature in BIOS (Enabled by default on my mobo)
    What memory remapping does is mapping the peripheral memory addresses above the 4GB address space.. :D

    Guys,is it useless upgrade windows 32 bit up to 4Gb?
    Even it doesn't show 4Gb,(show 3Gb)..Will it use 4Gb ram? I means isn't performance goes up to 4Gb,.

    As i heard,even it doesn't show,32bit either support 4Gb....

    correct me if am wrong..Said what I heard from the users who use 4Gb,bit shows only 3Gb.
