Why does XP only recognize 2.5 GB of RAM for me?

Oh wait a minute, I see it has an integrated gpahics chip, maybe that's why. How do I turn that off?

Edit-nevermind, that was probably a stupid suggestion.

I'm using A-data 2X2GB RAM I bought from newegg, identical RAM running in dual channel mode.

It's not a stupid question.  I had the same problem with an 8800 GT.

Is it recognizing the GFX card?  Mine wasn't recognizing the card, I had to download new drivers.

I should hope that my 8800GT is being recognized as I've been playing Crysis on high settings. But even if the integrated graphic isn't being used, would it still take memory?
