RAM upgrade for HP Laptop 15-db0004dx

[IrishAdvantage]

I'm looking to upgrade the RAM in my laptop.   Model number is 15-db0004dx

Processor is AMD Ryzen 3 2200U with Radeon Vega Mobile Gfx, 2500 Mhz, 2 Core(s), 4 Logical Processor(s)

Laptop 15 manual says 

* Two memory module slots (Ryzen, A9 processors)

*  DDR4-2400 dual channel support (Ryzen, Athlon processors)

According to System Information, it has 8 GB RAM installed now.  I don't know whether it's 1- 8GB module, or 2-4 GB modules, and don't plan to open it up to find out.  I plan to have my local IT hardware repair guy (I live in a very rural area) install the new memory once I have it.

Is this the right module to order?   

        8GB DDR4 2400MHz (DDR4-2400) PC4-19200 (PC4-2400T) Non-ECC Unbuffered 1.2V CL17 1Rx8 Single Rank 260 Pin SODIMM Laptop Notebook PC Computer Memory RAM Module Upgrade (8GB)

 I was planning to order 2 of them, in case what's in there now is 2 @ 4GB. 

FYI, the HP parts store lists this:   8GB, 2400MHz, PC4-17000, 1.2v DDR4 SODIMM but they're out of stock.

Thanks for the help!

Its specs

It has 8 GB DDR4-2400 SDRAM (1 x 8 GB) now and supports 32GB max. You can upgrade to

   (a) 16GB: Add SAME existing 8GB to slot 2

   (b) 32GB: install 16GB each to both slots using  : https://www.crucial.com/memory/ddr4/ct2k16g4sfd824a/ct14359362

If you want to get a matching 8GB module to add to your existing 8GB module, you can run something like CPU-Z  and it will tell you what is installed.
