So I just purchased an Alienware M17x R4 with 6GB of pre-installed RAM because I did not see any point in paying extra for RAM that I could just install myself. I ended up purchasing 16GB of DDR3 1600MHz RAM off of Amazon and when I went to install the 16GB of RAM I was unable to find where the 6GB of pre-installed RAM was located. It does not appear to be located in the same location where I was able to install the 16GB of RAM. Not sure if anyone else has noticed this or if I am just not looking in the correct area. Thanks!
