I just purchased an Aspire 7 Laptop (A715-72G-79BH)
It comes standard with:
GeForce GTX 1050 4 GB GDDR5
Intel Core i7 8th Gen 8750H (2.20 GHz)
8 GB DDR4 2400 Memory 
1 TB HDD
Comes standard with 8gb of RAM and i'd like to upgrade it to 16Gb.

I'd like to use just a single stick of RAM and leave a slot open for an m.2 card in the future.

For the life of me I can not find any information about the RAM in this laptop. There are plenty of places selling ram for the A715-72G line, but they are selling both Single Ranked and Dual ranked.
Does it matter if I'm only using one stick? Would it be better to run 2x8gb and forget the m.2, and if so, does it matter if its Single Ranked vs Dual Ranked?

I'll admit, my knowledge of RAM is limited, and these questions have arisen as a result of me trying to figure out what RAM to get.

This is what I THINK I should buy (it was suggested when i typed in the model of the laptop) - https://www.crucial.com/usa/en/aspire-a715-72g/CT12463062

Any information would be greatly appreciated. Also, i've flirted with the idea of upgrading to ddr4 2666. The same questions apply to that speed of memory as well.

Thanks in advance.
