    I recently installed Windows 7 Ultimate 64 bits and after failing to install with 8 GB of memory, reduced the memory to 4GB and the installation succeeded, however Windows will never complete the startup after I add the 4GB extra to make a total of 8GB.
    Memory installed: 4 banks of 2 GB each Crucial Technology CT25664BA1339
    Video card: ATI RADEON HD 3800 series
    Motherboard:Intel original DP45SG
    CPU:Pentium Dual- core E2220 2.4 GHZ PRODUCT CODE:BX80557E2220
    Hard Disk:Western Digital 1.5 TB SATA model WD15EADSSP
    I get many different messages:
    BAD_POOL_HEADER
    STOP:0X00000019

    Ntfs.sys
    PAGE_FAULT_IN_NONPAGED_AREA STOP:0X00000050

    WimFsf.sys
    PAGE_FAULT_IN_NONPAGED_AREA STOP:0X00000050

    MEMORY_MANAGEMENT
    STOP:0X0000001A

    Windows Memory Diagnostics Tool
    Status:No problems have been detected yet

    I tried switching all memory modules and I discovered that one of them is defective because Windows does not start with this module installed. However I wonder why the Windows Memory Diagnostics Tool did not detect any errors.

    After running the Windows Memory Diagnostics Tool again with no issues I was able to see the login screen, I entered my credentials only to see
    PAGE_FAULT_IN_NONPAGED_AREA followed by a quick restart. Tried after the restart to enter in Safe Mode and I see MEMORY_MANAGEMENT

    Hi,
    This is an obvious hardware fault!
    The Windows diagnostic will tell you what error was caused by the faulty memory chip(s) but doesn't know where or what the problem is in the actual chip, that's normal for the OS.

    Windows 7 will read as much memory as you can put on your board as long as the chips all match.
    I work with 12 GBs of Patriot DDR3 on a tri-channel Asus mobo and i find no problem at all.

    I strongly suggest you replace the faulty chip before all other data gets corrupted and lose everything you have; even on other hard drives than the OS (C drive).  It happened to me before with brand new memory chips.

    Your issue will be solved then.

    Best regards,
    Remi
