I would like to upgrade my Asus X550LC memory. Currently I have a 2 memory sticks of 4Gb each (one of the memory is soldered). I would like to replace the second memory stick (a M471b5173bh0-Yk0 Samsung 4Gb DDR3SODIMM 1600Mhz) with a one that with 8Gb. I am note sure if it is OK that I can add a Dual rank memory since the memory I have is a single rank. I searched on the internet to determine whether my motherboard support dual rank, but I did not find anything relevant.
Any comment or a suggestion is welcome Thanks in advance
