Is that a hardware limitation or a BIOS limitation?
I remember when I bought my XPS M1530 it could only take 4GB, but after a year or so a new BIOS with support for 8GB arrived.
I imagine that it is a BIOS restriction but I do not know that for a fact.
8GB is all that Dell says will be be supported on that system.
Chipset and CPU can def do 16gb - let's hope Dell address this
note.on Kingstons site they state 2x8GB will work for XPS 15....
hey..... that was odd I have a mail with a post update - where "jj826" posted here that he tried with 16GB and it worked... however the post has been removed?
