Hi:
The Ryzen processor your notebook has runs the memory at 2400 MHz.
Your notebook's M.2 slot supports both SATA and NVMe (PCIe) SSD's.
I would get this memory if you can in Egypt.

Thank you! This should work? And can I add more than 16 GBs?

You're very welcome.
Yes, that would be the 8 GB memory chip you want to buy.
You can also do this to determine what the maximum amount of memory you can install in your notebook is...
1. In the search box, search for cmd and click Run as administrator. This will open the command prompt.
2. Once command prompt is opened, type wmic memphysical get maxcapacity and hit enter. There, it will show the maximum RAM capacity your PC's motherboard can support.
The capacity is shown as Kilobytes, so you have to convert it to Gigabytes by dividing the number provided in the report by 1,048,576.

Thank you, I didn't buy it, *yet*. I was asking before I order it, I've heard that 16 is the max, some people say it's 32 so I'm not sure, I'll get back to you as soon as i receive it tomorrow.
