SYMPTOMS

A Windows Vista-based or Windows Server 2008-based computer uses a graphics adapter that has at least 4 gigabytes (GB) of physical video memory. After you start the computer, the physical video memory capacity is displayed correctly on the screen during the Power-On Self Test (POST) stage. However, after you log on to the system, the system incorrectly reports the physical video memory capacity.

This incorrect information appears in different user interfaces. For example, when you view the adapter information in the Display Settings item in Control Panel for a graphics adapter that has 4 GB of physical video memory, the Dedicated Video Memory section shows only 0 megabytes (MB).

CAUSE

This problem occurs because some APIs represent the video memory in 32-bit values instead of in 64-bit values.

RESOLUTION

Note The following hotfix is only for 64-bit versions of Windows. No hotfix for 32-bit versions of Windows is available or expected. 

This hotfix only corrects the incorrect physical graphics memory information that appears in the Display Settings item in Control Panel. Other user interfaces, such as the MsInfo32.exe interface, are not changed by this hotfix and continue to show inaccurate information.
