I have an XPS 600 that need more RAM, but wonder if the motherboard will not handle what I want. I presently have 2x2GB cards in 2 of the 4 available slots. I was trying to install at least 8GB of RAM, will that be possible on this "dinosaur".  the model no. on the m.board is: CN-OGC375-13740-5AN-0055.

Any help you can give me would be greatly appreciated.
