If I were to upgrade to 4GB of RAM, would Windows see it all and be able to use the full 4GB of RAM? I have looked at my motherboards manual, it says it can support 4GB of RAM. So if I were to upgrade to 4GB of RAM, would I be likely encounter any problems?

Should be fine as long as your are using service pack 2, XP can cope with up to 4GB.

One to check is this:
You said your motherboard manual can support 4GB of ram. I assume that this the max it can support, right?
What I have found frequently, is often when you either fill all the ram slots and/or install the maximum amount of ram supported, the bios will lower the ram FSB speed. For example, if you install 4GB of DDR400, the bios might lower the FSB speed to 333MHz.

This is not to say that you will experience this problem, but it would be worth checking out on the motherboard manufacturers website. You may even find that there's a bios update available to overcome any such issues.

Thanks for the replies both.

Yes, it's the maximum the motherboard can support. Thanks, I'll check up on that. I've heard that even if you put the maximum amount of RAM in, Windows won't 'see' it all. Is this true?

I think there is an issue with anything over 3GB in XP but I'm not absolutely certain as I've read conflicting reports on this subject.

windows XP only allows the use of 3.25 G's for the RAM and the other .75 for systems swap space

i think this is correct i could be wrong but
XP can only handle up to 3.25 gigs

and what would you need 4 gigs for thats a bit of overkill for now anyway
