Hi guys,
First post. I just updated my memory from 2.5gb (2x1gb 1x512mb) to 4 gbs (2x2gb) of RAM. Oddly after doing the update, my BIOS recognizes it as 4gb but windows 7 still thinks i have 2.5gb. Ubuntu recognizes that I have 4gb of ram also. Im currently running windows 7 64bit. Any help on how to update it would be appreciated.
Thanks again,
Anthony

Hello and Welcome to Windows7forums...

Not to worry, as long as your BIOS is recognizing the full 4GB's you should be good to go.. Windows 7 addresse's/distributes memory a little bit differently then Windows XP and Vista.. that is why it's only showing up as 2.5GB's.. Meaning there's really nothing to "fix" persay.. The memory is there, it's just being used by other components.. (ei: video card, sound card, etc..)..

If you open the start menu and type the following: msinfo32 Then hit enter, a report will come back and you will see exactly how your memory is distributed.. If on this screen it does not say that you have a total of 4GB's "Installed Physical Memory" then there may be a problem.. but...
