Vista and Memory

[AliasBDI]

I have a Mac Pro desktop and installed Boot Camp with Vista Home Basic. So far there have been very minimal problems like Flash.osx being lost, the date and time being messed up each boot, etc.

But my main concern is that Vista will not recognize all of my RAM. I have 8GB of memory in the Mac. OSX recognizes it all, but not Vista.

Any ideas?

Based upon a quick search (http://channel9.msdn.com/ShowPost.aspx?PostID=281738) via Google, it seems that 32-bit versions of Vista will never be able to support 8GB of RAM; in order to see all of your RAM in Vista, you'll need to install one of the 64-bit versions.

It should also be noted that Vista reports the amount of RAM you actually have accessible for processes, excluding some administrative, carved out portion (I'd explain better, but that's all I remember from training, and I don't feel like looking it up right now)

As I understand it, all 32 bit versions of Windows OS's will only address 4GB of ram total. This is a limitation of 32 bit OS's in general.

Vista is no different that XP in this regard. You will need the 64 bit version of Vista to address more than 4 GB. However right now Apple hasn't written any drivers for 64 bit versions of Window's OS's.
