Don't trust 'some people'. Trust crucial.com: http://www.crucial.com/store/listparts.aspx?model=Inspiron%20N5030&Cat=RAM says 8 GB DDR3 PC3-12800 in 2 slots. So it's either 2x2=4 or 2x4=8, never 6!
I'm sorry if this question has been asked several times before but I've tried googling but I'm getting conflicting anwers. I have a Inspiron N5030 running 64 bit Win 7. What is the maximum amount of ram I can install? Some peope are saying 8gb and some 6gb. Which is correct if either?
