    Default 16GB RAM not working in M15x?!

    Hello everybody, I recently bought these RAM sticks for my m15x:
    Newegg.com - G.SKILL 16GB (2 x 8G) 204-Pin DDR3 SO-DIMM DDR3 1333 (PC3 10600) Laptop Memory Model F3-10600CL9D-16GBSQ
    I saw that some people were able to put 16GB into their system. So, I bought these hoping it would work. Now everytime I put them in they will just make my computer reboot. I tried putting 1 at a time. The only difference I got was:
    When I put 2 sticks in the windows logo would not even appear,and When I put 1 stick in I can see the 4 balls then it restarts.
    I have updated the bios to A09, and tried Memtest+, however, Memtest would also reboot and if it is in fail safe mode, It will freeze.
    Help Me Out! These are my system specs:
    Alienware M15x
    i7 620M 2.66
    4GB RAM (for now)
    Nvidia GT 240M
    Just in case, I am putting a picture of cpu z for my 4GBRAM:Click image for larger version.

    I think it is the CPU (the 620m has only 2 cores).

    You would need a 720qm or better if you want to use the 16GB ram.

    Yup that will work (and it is a great price), you can also get a faster CPU if you want more something even faster as well, but that will work just fine.

    I believe the R1 boards use the GM965 chipset, with a max RAM capacity of 8GB. Also, are you running 32 bit windows or 64 bit?

    Yes, I do have a 64 bit system and I bought my M15x in April 2010. So, I think it is r2. At least that's what I heard online.
