    I upgrade my laptop's ram to 8GB (2*4Gb). A 64-bit version of Windows 7 shows that I have 8GB of memory but there is only 3 GB of usable system memory. How i can use the 8GB. My version of the Bios is 2.00. In the Bios, i have not found the option "Enable the memory remapping feature".

    Such option doesn’t exist in BIOS and the whole thing is controlled automatically. BIOS update will not change anything.
    As far as I know on Toshiba notebooks you cannot “force” notebook to use defined amount of RAM.

    it is normal to say that this laptop supports up to 8 GB of memory and then the system only detects 3 GB.

    Start msconfig (in search type msconfig)
    Then go to ->boot -> advanced option -> make sure maximum memory is unchecked
