Hello

Just started testing Vista Enterprice 64bit, the PC has nVidia GF 6600GT
video card. With both the retail DVD and latest beta drivers, display
properties show there are 256MB shared memory used by the video
subsystem. Aero is disabled. Why is this and how can I limit the driver
to only using the card onboard memory.

Thanks

This isn't controlled by the OS. Check in the BIOS or in the display
properties for the card for a setting for this.

The card is PCI-Eand there are no settings in the motherboard BIOS about
shared memory.

As I said, there are no controls for this in Vista AFAIK. It would be
either through the settings provided by the driver, or the BIOS.

You could contact nVidia tech support as well.
 
Look in the BIOS for: "Frame Buffer Size" = Frame buffer size is the total
amount of system memory locked by the BIOS for video. A larger frame buffer
size
should result in higher video performance.

Also "Aperture Size" = Establishes the maximum amount of system memory that
the
Operating System can use for video memory. This is
primarily used for buffering textures for the AGP video device.
