    Only 8 GB Ram recognised of 12 GB


    Hello,
    i am dealing with a very strange problem right now.

    first of all, my system specs:
    PT6 SE Mainboard
    Intel Core I7 920
    12 GB ram (6 x 2GB DDR3)
    Nvidia GTX 260
    Windows 7 Ultimate 64 bit

    Recently windows 7 only shows me 8 of 12 GB Ram, when I check with CPUID it shows me all 12 GB ram. The bios shows me 8 as well.
    what is wrong and how can I fix this? I thought of the mainboard or the chips being bad but if that would be the case CPUID woudnt show me all 12 GB RAM.

    Enable 'Memory Remap' in your BIOS

    Uncheck Max mem from msconfig (msconfig>Boot>Advanced options)

    Also check in System Configuration for Maximum Memory set to Zero (0)

    If not, set that & save & reboot computer.

    I checked Maximum Memory and it was allready unchecked.
    And I still cant find Memory remapping in my Bios...
    its not under Chipset.

    Each different Mfg of Bios's seems to hide it it different sub-menus. Sometimes, I have to go through each menu & sub-menu, 1 at a time until I find what I need to change.

    I just went throu every sub menu & menu in my Bios and there was no such thing as Memory remmaping. How can this be? could it be that the Asus PT6 SE doesent support that function?

    What speed are you running the RAM at? When using all six slots in the P6T it is recommended not to use any of the XMS settings.

    And what does XMS mean?
