And i am wondering if i can add 1x8gb of this RAM - http://www.flipkart.com/kingston-hyperx-ddr3-8-gb-1-x-gb-pc-ram-khx1600c10d3b1-8g/p/itmdg5dhjqffe2vb?pid=RAMDG5DHBP3SQVZH&ref=50c475b8-d25c-42f0-a6e4-547ef1d2acdd
And later upgrade another 8GB of same model...?
Previous ones are in B1 and B2 (2nd and 4th slot) slots (DIMM) of my mobo, and will add new one at A1 (Closest to CPU).
