Am I Able To Fit This Into My Laptop?(See Links)

[jamieyates14]

I was wondering if I could fit this(http://www.crucial.com/uk/store/mpartspecs.aspx?mtbpoid=107F9AC8A5CA7304) into my laptop, the website says that it is compatible but I have no extra slots. So would I take the old 2Gbx2 out and just put the 4Gbx2 in the same slot? Or would the 4gb Modules not fit into the original slots?

Also my laptop is a Sony VAIO VPC, it is capable of handling 8gb of ram it says.

They'll fit, but you need to remove the original modules.

Ok thanks, so they are the same size? Exactly the same?(Sorry for keeping asking, I just need to be really sure)

I don't know if they are exactly the same height, but they have the same number of pins, they have the same width and they'll definitely fit.
