Win7 x64 Virtual memory?

[Noid]

My previous thread was closed for some reason

I have 4GB of DDR400 installed in my ASROCK 939S56-M ( SiS 756 chipset )

BIOS says 4096
CPU-Z says 4096

However Task Manager and System Identification says only 2gb PHYSICAL memory.

I just found another utility in Win7 under

Performance Information and Tools > Advanced Tools > System Information
(View advanced system details in system information )

What is 'Virtual memory' ...?

Is this what happened to my unused 2gb of physical memory?
Or is this a combination of pagefile and the 2gb of physical memory?

Virtual Memory is physical memory + your page file. In your case you have 2gb RAM AWOL, so you have 2gb RAM+2gb page file=4gbVM

Ok, thanks. That's what I thought, but wanted confirmation.

Actually it's not, however you're right in that is how the stupid System Information tool in Windows calculates that value.
