Ram numbers can be confusing as they are based on powers of 2, so there is no such thing as 1G of ram... fetching my calculator hold on....

2 raised to the 30th power would be 1,073,741,824, some people just say 1024 raised to the third.

It gets even more confusing with hard drives and then more so with telecom.

Another test of the memory size is not the system properties but using task manager to see how much memory is available for commitment. Sure the BIOS can count it but can the computer use it?

I got a lecture from Microsoft once that mixing sizes wasn't a good thing, don't know never verified it myself... anybody?
