    Correction:
    I updated to Windows 7 64bit Home Premium and you are correct about Windows 32bit OS not able to support more than 4gb. This is why I updated.

    Hi all
    as i had the same problem, i dropped in the give my experience and solution to the bios don't show full mem capacity problem.

    you can also see this thread where i 1st posted about this problem:
    Windows 7 64bit recognize 4GB of 6GB RAM - Rage3D Discussion Area

    the problem on my PC was a bent socket pin on the mobo (as the i7 cpu doesnt have pins just flat surface connectors), it was pulled back to place with a tiny screwdriver and a magnifying glass and now all is working fine and all 6GB of mem are recognized and used by the system.

    hope this will help somone in the future.

    Right.

    Sone 32-bit OS do offer that already, for free. MS Windows are not among them.
