Getting Windows to use more than 2 Gig of Ram on 1.1 Mac Pro?

[lloyd709]

I'm running Vista on a 2006 1.1 Mac Pro under Boot Camp. The computer has 12 Gig of memory in but Windows will only use 2 Gig of it. Is there any way I can get it to use more than 2 Gig - even if it means upgrading to Windows 7?

...is it a 32bit version of winVista?

If so, it should see ~2.7Gb of RAM like winXP does on my whitebook...

If its a 64bit version are you running it via a VM (virtual machine), maybe your just allocating only 2Gb of RAM to your VM partition?

You can also try adding the 3gb switch as per this link:

Not tried it, but then again I wouldn't run any Windoze version on a Mac to begin with.
