Changing Amount of Shared Memory in Windows 7 on BootCamp

[mr.staggs]

I installed win 7 Home Premium, and I am being robbed of my ram because I can't change the shared video memory settings. Does anyone have a solution to this? I have the iMac with the ATI 4670 so I already have plenty of VRAM for what I do.

You are not being robbed. Windows 7 lets video cards "stake a claim" to system RAM as extra VRAM, but it will only be used if you are ever in a situation where the video driver actually *NEEDS* it, and it's available. (In a game where system RAM needs are lower than VRAM needs, for example.)

ok well, I just made an "educated" guess thinking that was my problem. Is that why when I go to system properties, it says 4.00 GB (2.9 Available)?

if it is anything like windows xp 32bit, Wdows can only address 4gb memory. this includes vga memory. if you add them together you may see that it adds up to 4gb

mr.staggs it definitely sounds like you installed a 32 bit version of Windows. If you had installed a 64 bit edition and some RAM was being reserved for the GPU you should see closer to 3.5-3.7 GB available.

If you bought Windows retail, just install from the 64 bit disc instead.
