    Hello Everyone...

    I need some help here..

    I have a notebook that been 2 years use. Mine was Zepto Znote 6615WD, Denmark Assembly, bought in UK.
    Now, i'm having this weird condition that i cannot upgrade the memory upto 4GB or 3GB, i stuck at the max 2.5GB. The sound and modem wont start if i put 4GB or 3GB mem.
    I'm thinking that this is the cause of a bug in BIOS.
    My motherboard is ACER MPAD-MSAE Customer Reference Board, with the latest version BIOS from Zepto as the manufacture is version z1.09. ftp://ftp.zepto.dk/

    Now, i want to ask you guys/girls...
    Can i use an ACER BIOS Release for other motherboard and flash it to my notebook motherboard?
    Which one is it?

    My Notebook Specs:
    T7600, Nvidia 7600 go, 2.5GB mem, 160GB HDD, 15.4".
    BIOS: ftp://ftp.zepto.dk/Notebooks/Discont...IOS/v1.09v.iso

    Thank you for everyone that wlling to help.
    You can mail me at:
    Thanks

    BG,
    iyep

    The memory limit could be a limit of the machine. I'm not super famillar with Zepto machines. Upgrade to the latest official BIOS to see if than helps. You could also run memtest on your sticks to see if either is defective.

    Have you updated your BIOS to the latest version available from Zepto ? Don't risk flashing an Acer BIOS, as it can brick your mobo, and you'll have to send it to Zepto to have it revived.

    Because your notebook is based on the Napa Platform, it has a 32-bit chipset/memory controller. It will not address any more than ~3GB of RAM.

    I have seen many notebooks with the 7600GO having addressing issues due to a bug related to the Nvidia GPU, so try out the latest BIOS build and that might solve your problem, but you'll be stuck at ~3GB....

    @Zaz
    In the manual, it says that this notebook memory support was max at 2GB.
    But, i believe that the intel 945PM can handle upto 4GB mem.
    I am using the latest release from the manufacture site ( ftp://ftp.zepto.dk/).
    The version is z1.09.
    I had a memtest and all went well.

    @Andy
    Same answer for BIOS.
    About the GPU, should i upgrade the GPU BIOS too? if there any.

    Thanks
