RE: Max Memory on Dell Inspiron 15 (3521) Touch
I do trust Dell, which is why I am doing my research because they don't often lead me astray. I do know that the technology does move fast and sometimes with BIOS updates, or new CPU's/mobo chipsets the systems "CAN" indeed support more than they originally could. It would not shock me at all that Dell says 8GB and supports 8GB, but it might in fact run just fine with 16GB.
Thanks for the link to the Crucial 4GB DIMM on Amazon. In the reviews, somebody posted that they put this chip into a 3521 and it worked flawlessly, so that is exactly what I wanted to know. My plan was to put this laptop on 8GB of RAM and now I know that I can do it.
