Hello guys,, i bought a notebook VivoBook X555QA-XO085T.

Someone can help me with this. I've tried to find any info in manuals, videos ,etc i can't find any info related.

Need to upgrade my laptop ram to 16GB and i don't know which brand, which frenquency, what speed, and how many pins.

The 8GB model i have is Intern RAM, so i don't know how many pins the RAM must have, or " PC4-19200" info. I only know because windows tells me the ram internal memory is a DDR4 with 2400MHZ. The BIOS can't show me anything about this internal ram. Using CPuz app i know the internal ram has frequency: 13-13-13-30-43
but i found that Crucial brand has some 8GB sodimm at 2400MHZ but with Frequency of 17CL, so how can i know if i can upgrade with those rams?

I'll add pictures. Hope you guys can help me. Because Asus official support and my retail can't.
