I want to upgrade ram on my laptop. It has one empty slot. I am thinking of upgrading to one more 8gb (total 16gb ram). What I am not sure about my soldered 8gb ram specifications like channel mode (single or dual) and chip organization (x8, x16). soldered 8gb ram speed is 3200 MT/s. How do i know of this before buy a new ram (is it necessary too to know of this).
so, which ram should i go for???
