Dell G5 5587 RAM Upgrade

Hi,

it has been almost 2 years since i bought my Dell G5 5587 laptop with i5-8300h cpu and 8gb (2x4gb) of 2666MHz ddr4 RAM, and i believe it is finally time for me to upgrade to 16gb. Unfortunately there are so many upgrades on the market that it is hard to make a choice, and it got even worse when i came upon an old post that mentioned compatibility problems between my laptop and ram sticks that support xmp. From there i decided to see what ram sticks would work for me according to crucial compatibility tool

https://www.crucial.com/compatible-upgrade-for/dell/dell-g5-5587

Well, lets just say that after searching on that website i got confused even more as it showed compatible ram with 3200MHz that i'm pretty sure would not work on my laptop that supports only up to 2666MHz ( correct me here if i'm wrong ? ). Or maybe it does work but runs at lower speed and is basically useless for me to buy ?

So the reason im writing this is, i would really appreciate if someone would answer these simple questions for me:

1. Does Dell g5 5587 really cannot run ANY sticks that support xmp ? If so how do i tell which ones are without xmp, most websites doesnt mention that. My first choice that i wanted to buy were Corsair Vengeance 2666MHz DDR4 2x8gb but i believe they do have xmp built in. I also considered HyperX Impact 2666MHz DDR4 2x8gb. ( links to both below, sorry for non-english website but the spec is visible )

2. Is my laptop actually able to run 3200MHz ram like the crucial website says ? I've seen many posts saying that all the RAM sticks from there would definately be compatible with my desktop. 

If that makes any difference i'm running the latest 1.13 bios version.
