Stock 16GB DDR4 2666 memory single rank or dual rank in my HP 17z-ca300 (upgrading to 32GB) ??

HP Recommended
17z-ca300
Microsoft Windows 10 (64-bit)

I am attempting to order 32 GB of memory for my newly purchased HP 17z-ca300.
I will be getting 2x16GB dual-channel (Kingston Hyper X Impact, G.Skill RIPJAWS, Corsair, or IPQ).
My question is: should get single rank or dual rank? As per usual the internet searching has netted varying and conflicting information. It seems that it can be extremely situational which is better. Since you guys know my computer specifics better than anyone, what say you?

Thank you all again! This HP community has been immensely helpful over the past week and has led me to finally getting the exact laptop I needed at a price point that was extremely fair!
I ordered every option available, this is how my specific machine is spec's out:

HP 17z-ca300
- Natural silver
- 17.3 full HD (1920 x 1080) display
- Full-size island-style backlit natural silver keyboard with numeric keypad

- AMD Ryzen 7 4700U processor + AMD Radeon graphics
- 16 GB DDR4-2666 SDRAM
- 256 GB PCIe NVMe M.2 SSD + 1TB 5,400 RPM HDD
- Intel AX200 WiFi 6 (2 x 2) w/ Bluetooth 5
- DVD-writer

Hi:

 

See if the free utility that I zipped op and attached below will provide that information for you.

 

Run the program and close out of the summary window.

 

On the left side of the window, click to expand the memory section.

 

Click on your memory module listed there.

 

On the right side of the program window, there should be a number of ranks report about halfway down.

 

This is the report from my desktop PC which indicates the memory I have installed is dual rank.

 

Number Of Ranks: 2
