  1. My motherboard will take 4gb but only alows 2gb ram, however bios will read upto 3gb with windows at 4gb or just under, but when 3gb is in I lose the win 7 logo on start up and get the vista bar which usally means ram prob but had no blue screen or is my processer holding me back

    Sound like a memory problem. Are the memory sticks you are using . The same kind or differant brands? Are they the right specs for you computer? Also you might want to post your system specs. This will help out with someone assisting you.

    There is a way to fix this issue under Windows 7 if you see this.

    1. open dos session using Run as Admin
    2. type: C:\Windows\system32>bcdedit

    Windows Boot Manager
    identifier {bootmgr}
    device partition=\Device\HarddiskVolume1
    path \EFI\Microsoft\Boot\bootmgfw.efi
    description Windows Boot Manager
    locale en-US
    inherit {globalsettings}
    default {current}
    resumeobject {xxxxxx-xxx-xxx-xxxxx-xxxx}
    displayorder {current}
    toolsdisplayorder {memdiag}
    timeout 30

    Windows Boot Loader
    identifier {current}
    device partition=C:
    path \Windows\system32\winload.efi
    description Windows 7
    locale en-US
    inherit {bootloadersettings}
    recoverysequence {xxxxxx-xxx-xxx-xxxxx-xxxx}
    truncatememory 0x800000000
    recoveryenabled Yes
    osdevice partition=C:
    systemroot \Windows
    resumeobject {xxxxxx-xxx-xxx-xxxxx-xxxx}
    nx OptIn
    numproc 4
    usefirmwarepcisettings No

    3. C:\Windows\system32>bcdedit /deletevalue {current} truncatememory
    The operation completed successfully.

    Reboot the system your problem will be corrected and the system will show the right memory usable amount.
    I've done the above on all my new and older systems were not showing the corrent figures.
    In my 32GB system I was showing 30.4 where it should be 31.4GB usable. 4GB were showing 2.91GB now shows 3.7xGB depends on what you have in your system.
