  1. Could be several things, first make sure you have the memory in the right slots, if that is so, try this

    click start button and enter msconfig in the search field and hit enter

    go to second pane - Boot

    click advanced settings and make sure that max memory is unticked, if it is not, untick it and reboot.

    If you are still only seeing 4 GB try testing each stick separately with memtest or similar application.
  2. Memory is in the right slots.

    I did enter to msconfig ( boot advance ) as well unchecked and still shows 4 GB memory ram total.
  3. Thanks again for your prompt response.
  4. Hmm sorry to hear that it is not an easy fix.

    Try going through Ram not detected (Troubleshooting) from ASUS site.
  5. Thanks again lothdk.

    The Asus forum looks promising.....

    That being the red ones, 2nd, 4th and 6th from CPU right ?
  7. Does your BIOS show 1 XMP profile option or 2 XMP profile options?

    Hello...

    I make sure all of them are in the right slots.....i think it has to do how these are configure in the bios system?

    Thanks again for your help!

    It does show 1 XMP when is not set to manual configuration?

    Perhaps it has to do with CPU voltage?

    Under profile options it shows only this (X.M.P.)?
