Hi:

Yes, since your notebook has a Ryzen processor it has a 2nd slot to install another 8 GB of memory.

Below is the link to the service manual:

Are you sure about it? Cause when i check this laptop using s/n i get information like this ( only 1 sodimm slot)

Your notebook has a Ryzen processor, correct?

Chapter 1, page 1 of the service manual indicates that there are two memory slots for the notebooks with the Ryzen processors.

Maintenance and Service Guide (hp.com)

Memory Two SODIMM slots, not customer accessible or upgradeable supporting up to 16 GB of RAM
DDR4-2400 dual-channel support (DDR4-3200).
Supports the following configurations:
● 16 GB (8 × 2)
● 12 GB (8 + 4)
● 8 GB (8 × 1) or (4 × 2)
● 4 GB (4 × 1)

Chapter 5 has the memory removal and replacement procedure:

Yeap, i have laptop with ryzen cpu. I don't have access to it right now so i can't check. That's why im asking about it. So i can add 2nd 8gb ram? 

[Paul_Tikkanen]

Yes, you can add another 8 GB DDR4-3200 CL22 memory chip in the empty slot.

Ok, thanka. Last question. Ram has to be 3200? Or can be lower? Ofc i don't want to affect the performence of it

[Paul_Tikkanen]

You're very welcome. 

Your notebook's Ryzen 5xxx processor runs the memory at the full 3200 MHz speed.

So, you don't want to install anything slower than that. 

The older processors referenced in the manual run the memory at 2400 MHz.

I have exactly this cpu RYZEN 3 5300U. So ram has to be 3200 mhz at least?

[Paul_Tikkanen · Accepted solution]

That is correct. 

DDR4-3200 CL22.

Nothing more, nothing less.
