I am new to the forum and just got my notebook. It came with 4gigs of Ram but I run a Virtual machine and would like at least 8 gigs of ram. I have been searching threads on adding ram and I came across a bunch of threads where people were having trouble adding ram to these machines. What ram should I get? Can I use a 4gb stick instead of the 2gb stick? I would like to get the most of the the ram slot under the keyboard so I was hoping on adding a 4gb stick. Could someone please paste a link or two on something that will work?
