Increase Shared Video Memory in Windows 7 - Boot Camp

[LukeSS]

hi guys, i have 4 gb of ram, and would like to increase the shared video memory in windows 7, that i am using via boot camp. i know you can do it using the bios, but because there is no bios, is there any program that emulates the bios for boot camp, or another solution to do this?

then, why does windows 7 read just 3 gb of ram, when i have 4?

What machine are you using? Many of the earlier Intel Macs could physically take 4 gigs of RAM but can only address 3, there is no way around this.

The 3GB thing is because you're running a 32 (x86) bit version of Windows 7, not 64 bit. That's the RAM limitation.

Furthermore, you cannot up the Shared Graphics memory amount, nor do you want to. There's no performance boost whatsoever, and you might see a decrease in performance because you have less ram for the system.
