Where'd you hear that? You can install it with much less than that, probably less than 512MB.
Really? Where'd you hear that? That doesn't make much sense to me. Would that be a requirement of any other PC with the X1900 XT too?

I'm beginning to feel like the only one here that had no problems with X1900 XT drivers with a untouched default install of Vista (no Boot Camp drivers).
instead of dusting off the install DVD. also doesn't appear to detect bluetooth either so my keyboard isn't working either
this is correct. You need more than 1gb of ram for the ATI 1900XT to work in Vista (actually for any vid card to work). I confirmed it last night after dropping another 2gb of ram into my macpro after vista had a resource conflict on my 1gb macpro.
Now vista works with no issues. One thing I noticed is the bootcamp drivers don't fully install, so it doesn't allow you to switch "gracefully" between vista and OSX. need to figure that one out! Anyone have any idea's on that? switching back to OSX nicely

I'm still like to hear why more than 1GB RAM is required for the video card to work, and what types of systems it affects. Seems to me this would be a pretty MAJOR issue for people wanting to upgrade to Vista (not that they shouldn't get more RAM anyway
).Um. Hold down Option at startup?
Or does your bluetooth keyboard not work at that point?

Well I don't believe it's an issue with the video card. This is just an educated guess, but I'd say that it has to do with the new memory management/performance features incorporated into Vista. Check out some articles on Windows SuperFetch such as the following:

Basically once started (and unlike other systems) Vista via this technology consumes all of your physical memory installed. By that I mean none shows as free regardless of how much RAM you have installed. If it's not actively in use, it's cached and preloaded with the applications that it expects that you're most likely to use. Once this gets good at what those applications are, the apps load much faster as their data is now stored on cached physical RAM as opposed to being read from the HD. I suspect that on a system with 4 cores, 1GB is not sufficient in Vista's implementation of it's memory management and thus you get the errors that you do, but they go away once you get to a larger installed RAM size. Again just my suspicion.
As a matter of reference as I write this from my MacBook with 1.5GB installed, Task Manager reports that I have the following:
1.5GB Total Physical Ram
1GB Cached
0 Ram Free
Same thing happens with my Mac Pro which has 2GB. Not what you used to see with XP, but this is one of Vista's new performance features.

never knew about that one, thought I had to switch the OS's by using the startup disk program that's in windows and also in system preferences under OSX. I wish I knew why the vid card wasn't working because to me it still doesn't really make sense. oh well, i'm happy it works now.
