which RAM?

[lord_tiso]

So i wanted to add a ram stick to my laptop to make it dual channel, The present one is an hkhynix 8gb 2666mhz .
Do i have to buy from same company or can i buy any ram?

You can technically buy any ram of the same timings and speed BUT often if it isn't the identical ram in the laptop a laptop will put it at the lowest speed which is 2133mhz. Depending on what cpu you have this can be a noticable impact on performance or it will just be a tiny one.

I am not sure, but refer to this video https://www.youtube.com/watch?v=bTS0ybQ3lCI&ab_channel=LinusTechTips . Also, make sure it is SO-DIMM 260-pin https://ca.pcpartpicker.com/products/memory/#t=15

I found a ram identical to the one in my laptop, will it work in it's best config?
