Hello
I am running Windows 7 Home Edition.
Dell OptixPlex 790


MSINFO32.exe says my System Type= x64-based pc.

I have four DIMMS for memory.
Two of them are currently populated.

Can I add two more 2GB DIMMS to get a total of 8GB memory?

Just because my System is x64, how do I know my Windows 7 Home System is x86 or x64?

Thanks

If you right-click 'Computer' and select properties, there is a System Type like '64-bit Operating System'. That means you have a x64 windows OS and can support up to 16 Gb depending on which version of Windows 7 Home you have.
