Hi there, I have a dell xps 17 (L702X) with 4gb RAM (2 sticks of 2gb each) and I want to add an extra 8GB (another 2 sticks of 4gb each) so to get to 12GB. Now, the laptop allegedly has 4 slots and at the moment only 2 are taken. I don't know much about hardware and about DIMM A,B, C and D, but the problem I am having is that I can only see 2 slots with 2 pairs of securing clips and both of them are already taken by the current sticks. Just below these two slots there is some space as to accomodate more memory but the slots are different and I tried to insert the memory modules I have already but it doesn't get in because the memory-module connector seems to have a slightly different shape (in that it doesnt have a pin.) Does it mean that the modules I need to buy are different from the ones I already have?
I went onto the crucial website and scanned my system to make sure that I had 4 slots and here's the report generated http://www.crucial.com/uk/systemscanner/viewscanbyid.aspx?id=356ECF4831D926C3&click=true, so judging from it I do have 4 slots but it looks like I have only two or at least, if they are 4, they have different memory-module connectors.
ANy idea please?
