Hi All have this Veriton M464 running windows 7  and need to run a program requiring 4mb or more, so fitted new suited chips to 4mb but it will only use 2.75 of ram although recognising the 4mb installed ? Also I note that when I look at the device manager it shows the co-processor not installed correctly and shows the yellow exclamation mark . When I go to download or upgrade the software it cannot do it and says drivers for this device not installed (code 28) 
Looking deeper the mainboard ID is a MCP730  
Bios version 08.00.15
SMBIOS 2.5
System BIOS id RO1-A4 
BIOS releas date 06/02/2008 

Two questions how can I get the software to update the driver for the coprocessor ?
Does the BIOS also need updating ?

Any help appreciated Paul

    32-bit systems have access limit to RAM management and no more than 4Gb can be attached.
    So, with the percentage consumed by Windows and GPU only 2.4 to 2.9Gb are available.
    Only x64 bits can manage more RAM.

    Yes.
    Just go to the Microsoft website and download an official ISO x64 and proceed with the installation.
