    i have an old Sz-483N, my bios read 3200MB ram although i have 4GB ram installed. I have just installed win 7 64bit and system panel showed 4GB ram (3.12GB usable.) Anyone knows what can i do to make the bios read the 4GB ram?? I tried finding a bios upgrade for sz483n, but there isn't any online. Does any one encounter this problem?

    If you have a 32bit version of Windows, that is all you will see and be able to use. You need a 64bit version to see the full 4gigs.

    There is a hack to get it to work, but, it is a hack.

    SZ4 is limited to 3GB RAM by the BIOS. If you want to hack, you need to hack the BIOS first

    I do not recommend to hack the BIOS. Especially with SZ4 where the chipset that comes with it is not designed to support 4GB. If something goes wrong when hacking the BIOS, you are going end up with a very expensive brick!
