Laptop pc Soldered RAM Memory advice/question

[divarx]

Hey,
I have "Asus x556ur" laptop with "Micron Soldered 8GB 2133MHz DDR4" memory, and I have 1 free slot to upgrade, im a bit puzzled about compatibility with soldered ram.

Will RAM with higher frequency than 2133MHz and different CL will be compatible with the existing soldered ram?
Does different DDR memory brand with the similar specs can cause compatibility problems? or do I have to find Micron?

For example will "Kingston 8GB 2666MHz 260pin 1.2V CL19" will be compatible with my Soldered memory?

Added CPU-Z pics for more info about the Soldered ram , thanks you

Anything is possible with ram, best thing you can do is just find ram with same speed and timings as original.

Anything you put in there will downclock to 2133 and negotiate the 'worst' timings between the two.

I'd just find something 8G 2133 15-15-15-35 to put in there, unless you needed more than 16G of aggregate RAM.
