2 GB ram only for windows xp boot camp?

Y

Yes

Original poster
I got a Mac Pro and use boot camp.
For OS X I get to use all my 9GB ram but for
Windows XP it recognizes 2GB only.

I think if I'd use Windows Vista, it would recognize all of it.

But is there any way to increase the ram usage for Windows XP?

Cheers
 
You can force XP to use up to 3 GB by adding a switch to its startup options. I don't recall it off the top of my head for certain, but I think it's "/PAE". If you search, you should be able to find instructions on how to do it.

But, yeah. AT BEST, you will get 32-bit XP to recognize a little over 3 GB of RAM. Your options to use more RAM are to use a 64-bit OS. For Windows, this is either a 64-bit copy of Vista (If you buy the "full retail" package of Ultimate, it will come with both 32-bit and 64-bit versions in the box; although you can only use the installation code for one, you don't get to use both. If you buy an upgrade copy, it will be 32-bit only. If you buy an "OEM" copy, or a full retail copy of anything other than "Ultimate", you'll have to make sure you get the 64-bit version, as they are packaged separately,) or "Windows XP Professional x64 Edition". You probably want Vista. It was 64-bit from the start, so it has better driver support.
