    I did some research and found that a person installed 4 gigs into an XP Pro O.S. He only had 3 gigs "showing" as well. I ran across several posts like this. Some said they read 3.2 gigs of ram. Ask mocrosoft. I am going to, (now). Good Luck.

    your OS is probably a 32-bit. there are 64-bit OS's, but there is not much compatable with them. i looked into this for hours, even something as simpe as antivirus is hard to find with a 64-bit OS.

    32 only supports 3 gb i believe

    64 is made for 4+

    The operating system determines whether its 64bit or not. You have the 32bit version. If you didn't it would say Windows XP 64bit Edition on the startup screen.

    Your PentiumD will run a 64bit OS, so you get the 64bit XP or Vista and use that. But you won't be able to use that 4 gigs in 32bit XP.

    So can I just upgrade my xp pro to 64bit? And as the last guy posted will this be a problem with software? or games?

    What you can do first is delete your Windows cache. The reason or part of the reason you only see 3GB of memory is because Windows counts virtual (hard drive) memory towards total system memory, and because Windows XP can address only 4GB of memory and your computer already has a GB of virtual memory addressed then you lose the extra GB of actual memory you have installed.

    If you do delete your cache, I don't know if any or all of your programs will still work.

    Windows XP will reserve 2GB of memory for its self and leave 2GB for other program usage.

    You'll have to enable the memory remapping feature in your BIOS to protect some memory addresses allocated to the PCI system. I think it's the PCI system. :)

    If you do all of this and it still doesn't work and you ask me why it doesn't work, I'm gonna say, "I don't know." because I don't have any experience with 4GB of memory and everything I've just spued at you is from various posts I've read.

    No. There may be some problems finding drivers for some more obscure hardware, common hardware shouldn't be a problem though. Programs won't be a problem, XP64 will run 32bit programs just fine.

    You can't just 'upgrade' to 64bit XP though, it will require a clean install.

    I'm running pro 64, drivers arent hard to find now that its been out for a while. Vista pretty much forced software company to get with the 64bit program
