Boot Camp/Fusion RAM problem

[rontheancient]

I recently got my 2008 Mac Pro and decided to use VMWare Fusion's ability to virtual boot off a Boot Camp partition. Aside from CS3/Microsoft activation issues, everything seems to be fine. However, some time after installing Fusion and XP (in Boot Camp), I added another 2GB of RAM for a total of 4GB. I set Fusion to use 2GB, but now, when I do a real boot into XP using Boot Camp, Windows only sees 2GB (1.99). I opened up 3DMark06 and it says the same thing. Anyone have a idea on whats going on here?

Thanks.

XP Pro or Home?

Whoops, sorry about that...

Windows XP SP2 Pro
Mac OS 10.5.2
1.3TB HDD
4.0GB RAM

And Mac OS sees all 4GB BTW.

It's a limitation of Boot Camp, and has nothing to do with Fusion. 32-bit XP and 32-bit Vista see up to only 1.99GB of RAM in a Mac Pro.

64-bit Vista (with Boot Camp 2.0.1 drivers available with the "early 2008" Mac Pro Leopard installation DVD) can address all your memory, but there are pros and cons to 64-bit Windows.

Not exactly the news I was hoping for, but thanks for all the help.
