I have a Dell Inspiron N7110 i7 with 8GB RAM, 1Tb HDD, full keyboard etc. I am running Windows 7 Home Premium, and I see that the limitation on RAM is 16GB with Home Premium, yet it seems as though the laptop hardware only supports a maximum of 8GB RAM (2x4GB Modules)? Is this true? If so, would upgrading my OS to Ultimate allow me to add more RAM. I want to put in 2x8GB RAM modules to give me 16 GB.
