Incorrect Memory Report from System

Right-click on 'Computer' and select 'Properties' or select System from the Control Panel, it reports I have 16G of Memory.

Don't I wish.

I only have 2G. Task Manager as well as the CPU usage Gadget both report that correctly. Just noticed the device manager reported it incorrectly. Other than that little spot, it's working great. Has anyone else seen this little detail?

Windows 7 64 Beta Build 7000
AMD Athlon 64 X2 4400+
2G DDR 400 OCZ Platinum
Gigabyte GA-K8N Pro SLI
MSI R4850 512M

Can you provide us with a screen shot of the screen showing the 16 gb and then another showing the 2gb? That would help me better think of where the problem may lie.

Here. One is the system report tool (the incorrect one showing 16G) the other is the task manager correctly reporting 2G.
