Hello, I have a NEW BUILD, I have a EVGA nForce 780i MOTHERBOARD with 4 GB ram (Two Corsair 2GB DDR2-800 modules) in MS Vista. It only shows that I have 2.75 GB when I go to the window that shows the hardware configs. How can I check to make sure I am accually using 4GB, or do I have a bad module. I believe I have them in the 1st and 3rd slots on the motherboard. Can someone please advise or give a solution please, thanks. Can I check my ram memory in a bios setting?? Will Vista show more than 2.75 GB of ram??You're using 32 bit Vista CORRECT?
If yes you're never going to see full use of those 4 gb of RAM.

You will need to upgrade to 64 bit Windows if you want to use the full 4 gb. But upgrading to 64 bit isn't without its own headaches.Hi, Yes, thank you very much, I am using 32 bit Vista Home Basic. The website made me feel so much better, I was thinking something was wrong. So can I ask this then, is it ever worth putting in more Ram in the future?No, not unless you switch to a 64 bit version of Windows.
