Physical Address Extension (PAE) Information

Hi there.
I'm currently running Windows XP Home Edition 32bit. As with all 32bit OS I can only use 3.25GB of RAM which is kind of annoying. I heard of something called Physical Address Extension (PAE) that can allow me to use more than the 3.25GB. I know almost nothing about it so I was wondering if someone could give me a bit of info.

Thanks in advance!

    The simple explaination of PAE memory extention is kind of like virtual memory without the harddrive. The system doesn't actually address more than 4 GB at once. It pages memory much like virtual memory, but much faster.

    Unfortunately, Microsoft has disabled PAE memory extensions in all consumer versions of Windows. So if that was your intent, you will not be successful.
  2. Ok, thanks for that. Looks like it's finally time to upgrade to 64bit 7 =P
