SYMPTOMS

The Microsoft System Information (Msinfo32.exe) tool reports the incorrect amount of physical memory in a Windows Server 2008-based or Windows Vista SP1-based computer that has more than 4 gigabytes (GB) of physical memory installed. Specifically, the tool never reports more than 4 GB of total physical memory. For example, assume that a Windows Server 2008-based or Windows Vista SP1-based computer has 8 GB of physical memory. However, the Total Physical Memory item under the System Summary node in the Msinfo32.exe tool reports less than 4 GB of memory.

CAUSE

This issue occurs because an incorrect data type is used to calculate the total physical memory in the Msinfo32.exe tool.
