Task manager shows 3200Mhz speed but in speccy(a program to see detailed information of hardware on your device) it's showing that RAM frequency at 1600Mhz
I don't know much but I think its because of single-channel correct me if I'm wrong
Also, what else other than frequency should I look for(if any) while choosing a compatible ram stick for the upgrade? and how one could get it upgraded without getting warranty void?

    Ram is 'ddr' double data rate, so it's 3200hhz and 1600mhz :) 

    The 'real' clock is 1600, but it can do an operation at the start and end of the request, so the speed gets doubled to 3200 , hence the difference

    Single channel and dual channel is different, dual channel is when there are two sticks running at the same speed and latency, you can talk to both sticks at once so it's much faster

    Ah sorry missed that, so if you are buying one stick, make sure it matches the same frequency (3200) and Latency (cl) as the other stick. You can get the latency by downloading CPUz and its under the SPD tab i think (or the memory one)

    As to not void the warranty this depends on the region, if there are no stickers, its just a case of be carfull when you swap the sticks, try and avoid too much static and you are good. if there is a sticker its generaly not possible to upgrade it without breaking that sticker which would void the warranty
