Hi, today I purchased 2GB of RAM and installed it into my computer (a Compaq Presario CQ50Z-100 CTO Notebook). I now have 2.5GB of RAM as opposed to the 1GB of RAM I had earlier.
I am running the Windows 7 Ultimate RC 32 bit OS. I need to know if I also need to upgrade to a x64 bit edition of Windows to use ALL of my availiable RAM. Thanks.
Solved! Go to Solution.

it shows 2.5G instead of 3 because the system used up some already.
Also, you need 64bit capable CPU to run 64bit OSes.
