Only 64mb Video Ram in Windows (Bootcamp)

[cobaltmetallic]

I have a 2GHx MacBook with 2GB RAM. I've read elsewhere that Windows recognizes the Intel GMA 950 as having 128mb of RAM. After installing XP Pro through Bootcamp, I can only get it to show 64mb max video RAM. I have tried installing the drivers off of Intel's site and reinstalling Windows, but I still only show 64mb max RAM. I know that the GMA 950 can handle up to 224mb and OS X only allows 64mb, but Windows should be able to use more than 64mb. How can I enable the computer to use more that 64mb?

when i had my mac mini it recognized the video card as having 128 MB of shared memory

wonder why yours doesnt

Did you try to install the drivers from the Boot Camp Drivers CD. This is assuming:

1) You ran Boot Camp to install Windows.
2) You made a driver CD like it asked you to.

Sorry if you did, it just seems like from what you said that you didn't try the Apple driver CD.

I did use the Mac Drivers CD. When I didn't get that to work, I tried downloading the drivers. I find it very odd that everyone else has windows recognizing 128mb ram while mine will only recognize 64. I am surprised that there isn't some way to change the allocated memory.

Could anyone else out there running XP with bootcamp on a MacBook let me know what kind of numbers they are getting with their video ram?

Is there a specific reason you want more than 64 MB of VRAM?

Because it is using main system RAM for VRAM anyway, as long as you have enough memory for your frame buffer (horizontal pixels times vertical pixels times bit depth divided by 8, times two for double buffered, or about 12 MB for the MacBook's internal screen at 32-bit color, triple buffered,) then it doesn't matter. All modern video cards will use main system RAM for textures if there isn't enough onboard memory, so since main system RAM and VRAM are the same thing on the MacBook, it doesn't matter.

Unless you happen to be trying to run a program that actually INSISTS on more than 64 MB of video RAM for some unknown reason.
