Which ram should I add to my 255 G8 3500U having 8 gb 2400Mhz CL17 ram?

[Ayushch]

My laptop name- HP 255 G8 Notebook PC (3K1G7PA)
Specs- 

Processor

AMD Ryzen™ 5 3500U (2.1 GHz base clock, up to 3.7 GHz max boost clock, 4 MB L3 cache, 4 cores)

Memory

8 GB DDR4-2400 MHz RAM (1 x 8 GB) Transfer rates up to 2400 MT/s.

Memory Slots

1 SODIMM

Internal drive

1 TB 5400 rpm SATA HDD

So, I want to upgrade the RAM, please suggest the best compatible RAM, 8 GB or 16 GB with names!

I'd go with this one:

Amazon.in: Buy Crucial Basics 8GB DDR4 1.2v 2666Mhz CL19 SODIMM RAM Memory Module for Laptops and No...

The DDR4-2666 MHz memory will automatically bridge to 2400 MHz CL17, because that is as fast as your notebook's processor can run the memory at.
