Question How to look for compatible laptop ram?

[lockdown744]

I am planning to buy an acer nitro 5 2019(Acer Nitro 5 AN515-54 53RN) but it only comes with 4gb or ram and I want to upgrade it to 16gb(2x8gb). What should I look for to determine if the ram is compatible with the laptop?

Any sticks of DDR4 memory working at 2666 MHz will work. Acer is a good partner with Kingston and Crucial, so pick this brand to be on the safe side.

I live the philippines and the only available 2666mhz ram is g.skill, the kingston ones are only at 2400mhz. Can g.skill rams work?
