16.0 GB (7.96 GB Usable)???

I just installed my new Asus Sabertooth 990x mobo and then I put in my 4x4 ram of Corsair XMS3

If anyone has experience with this, could you tell me what options there are to change in the UEFI bios...

I am also running windows 7 64 GB/ GTX 570/ 1 SSD.

  1. Hi there, check the max RAM.


  2. Check the system configuration settings
    This problem may occur because the Maximum memory option is selected incorrectly. To fix this, follow these steps:
    Click Start, type msconfig in the Search programs and files box, and then click msconfig in the Programs list.
    In the System Configuration window, click Advanced options on the Boot tab.
    Click to clear the Maximum memory check box, and then click OK.
    Restart the computer.

    Check possible issues with the physical RAM
    The problem may occur because there are issues with the physical RAM installed.
    Check whether you have bad memory modules

    To check whether you are experiencing this issue, turn off the computer, unplug the computer, and then swap the order of the memory.
    Make sure that the memory arrangement is correct

    Refer to the User's Guide of the computer to determine in what order the memory modules should be inserted into the memory slots. The system may require you to use specific slots when you are not using all the available slots. For example, the computer has four slots available. But you may have to use slot 1 and slot 3 if you want to use only two memory modules.
    Check whether memory standoff cards are used

    If you use a memory standoff card to hold multiple memory modules on the computer, the system may require specific configurations for this scenario. Therefore, the usable memory may be less than expected.
  5. What version of Windows 7 are you running? Windows 7 home basic only supports 8 GB of RAM.

    home premium gets you to 16GB.
