ASUS P5Q does reports 6 GB of memory instead of 8 GB installed. Win 7 64 bit

Discussion in 'Windows 64 Bit' started by Pehr Sjöstrand, Feb 7, 2010.

  1. I installed 8GB of memory on the motherboard P5Q but Windows 7 64 bit
    reports only 6GB. I have 4 DDR2 2GB boards installed. I have switched
    positions and do not think any memory bank is faulty. I use a Q9450
    2.66GHz. All works well but would like to know why it fails to report full
    installed memmory. Could it be a timing problem?

  3. Check your BIOS to ensure the Memory Hole Remap is enabled. Or,
    sometimes you have to reduce the clock speed of the RAM.

    Hi,
    For a full diagnosis download, unzip and run (no setup required) CPU-Z
    http://www.cpuid.com/download/cpuz/cpuz64_153.zip
    Now go to the Memory tab.
    - What size do you read in the "General" section?
    That should be 8GB in your system.
    Now go to the SPD tab.
    - Select each of the memory slots (Slot #1, Slot #2, etc.) while watching
    "Module Size".
    - Are all your modules there, reported with the same size?
    - Are all your modules reported as equal?

  6. This isn't an X58 mobo. The X58 mobos are all "P6" something from Asus.
