Could Windows XP support 4GB of RAM?

    I've been looking around on the Web for random things, and came across the website that features the Firefox Myths page. While it's been proven time and time again that the Firefox Myths page is complete bunk, his other pages are apparently actually good, so I checked it out, and found this. Important part is the bolded, but read it all.

    I'm always looking to increase my tech knowledge, so I ask the following questions -

    1) Is there any truth to this?
    a) If the answer is yes, can Windows use PAE to use 4GB of RAM?

    Well PAE is a real thing. relate this to a Video Card. VC's can be over clocked or made to go faster than rated, this is because the hardware does have a higer range. The same is true for windows. If it has the PAE switch witch allow to see over the hill, and you have a mother board that does support 4 gigs then you can accomplish this.

    You can run up to 2.75gb of RAM on the 32-bit edition of XP, I don't know what the limit is on the 64 bit edition but i do know that it's higher.

    I'm fairly certain that article is lying.

    You can go up to 128GB of RAM on certain 64 bit Windows OS's. As for overclocking to support 4GB I'd avoid that if I were you. Sounds like a good way to break some components.

    Now Windows XP Pro does come in a more expensive (and less common) 64 bit version. You can easily get 4GB RAM supported by going that route too as long as your CPU is 64 bit.
