Hello<br />
I am running Windows 7 Home Edition.<br />
Dell OptixPlex 790<br />
<br />
<br />
MSINFO32.exe says my System Type= x64-based pc.<br />
<br />
I have four DIMMS for memory.<br />
Two of them are currently populated.<br />
<br />
Can I add two more 2GB DIMMS to get a total of 8GB memory?<br />
<br />
Just because my System is x64, how do I know my Windows 7 Home System is x86 or x64?<br />
<br />
Thanks

How much memory can my system support

Components are those devices that are internal to a computer -- the PC boards, the central processor (CPU), the memory (RAM), disk and video controllers and so on.
