I'm not great with hardware, this is my first time upgrading RAM.
My notebook is Asus VivoBook X556UR. It seems to have 1 slot soldered (4GB in my case) and 1 free slot.
From what I gathered the soldered RAM is MTA8ATF51264HZ-2G1 with 2133 MHz and CL15.
The CPU is i5-6200U and it seems that max supported RAM speed is 2133 MHz.
In my local store the only 8GB choices are:
  • Kingston KVR32S22S8/8 with 3200MHz and CL22
  • Patriot PSD48G266681S with 2666MHz and CL19
If I understand correctly the CPU should just force any of these two to use 2133MHz frequency and they should work just fine?
But because of CL, it would be better to choose Patriot because the latency will be lower and close to the soldered RAM latency.
I've read that mixing RAM from 2 different companies and with different latencies is not a great idea but I don't have much choice here.

Go here and run the scanner see what it shows.

Cruical suggests Crucial 8GB DDR4-2400 SODIMM, CT8G4SFS824A (CL17).
And kingstonmemoryshop.co.uk suggests Kingston 8GB DDR4 2666MT/s SODIMM, KCP426SS8/8 (CL19)

I also found this in local store: Kingston Fury Impact SODIMM 8GB DDR4 2666Mhz, KF426S15IB/8 (CL15).
