  • Question

  • Hey guys,

    Windows 7 is only detecting 16GB out of 24GB in my system - any ideas?

     

    Windows 7 Home Premium

    Asus Rampage III Extreme

    Intel Core i7 x 990

    6 x 4 GB RAM Corsair Vengeance

    2 x nVidia GTX 570 SLI

     

     

    Thanks!

  • Hi tenekox,

    Windows 7 Home Premium 64-bit has the limitation that it can only address 16GB of RAM.  If you would like to utilize more memory than that, you'll need to upgrade to Windows 7 Professional, Enterprise, or Ultimate.

  • Hi Tom,

    Question I have is...given that tenekox has 6 x 4GB RAM, will he be running 3 sticks on triple-channel and 1 stick on single-channel, if he continues to run Windows 7 Home Premium 64-bit (assuming the other 2 sticks are redundant)? Or will the system run 4 sticks on dual-channel?

    Thanks.
