I have Samsung lapatop with 2 Gb RAM and i want to upgrade it . Now the question is my laptop has 2 slots. 1 filled wih 2gb ram and another one is empty. that empty slot i want to fillup with another 4 gb ram(which makes 6gb total). 2 Gb Ram specification is DDR3-1333MHz-204pin SODIMMM RAM(PC3-10600S) and manufacture code is M471B5773CHS-CH9....Now i am going to buy another 4gb RAM which has manufactring code is M471B5273CHS-CH9 (rest specs are same). so should i buy this RAM? i mean will there be some compatibility issue? or which kind of RAM should I prefer?(tell me specs if you can)

Thanks in Advance

    The most important characteristics when changing RAM are:

    • RAM size (SODIMM in your case)
    • RAM type (DDR3)
    • RAM version (PC3-10600)

    From what I found on Google, that 4GB ram you found has the same parameters, so there should be no compatibility problem.

    However, as far as I know you can only get the best perfomance when using a pair of two identical ram modules. So I would recommend you buy a second 2GB M471B5773CHS-CH9, or in the best scenario, two 4GB M471B5273CHS-CH9.

    EDIT: Using two identical module for best performance is not true, thanks acejavelin for pointing it out. Still, I'd recommend two 4GB ram (because one never has enough ram ^^)
