[SOLVED] I want to buy a RAM, but I don't know which one. Can you help me?

Greetings, I have a fairly old laptop and would like to expand the RAM memory it currently has. My computer has 4 RAM slots, of which 2 are occupied by 2 GB DDR3 667 MHZ type memories, below they have all the complete features (https://prnt.sc/1sln6j5) In a well-known online store I am offered several models, but none it is exactly the same (here I leave them all: https://prnt.sc/1slp6cq) My idea was to install 2 modules of 2 GB each, my question is: Which of them is the most compatible with my computer? Thank you very much in advance for your help.

Make and model of that "fairly old" laptop?

You can only install RAM that is supported by that laptop's "build".

Go to the laptop's manufacturer's website.

Search for the laptop and look for the User Guide/Manual in particular.

There should be some listing of supported RAM modules along with the supported configurations of RAM modules.

Side note: I am not sure but you switched wording from "laptop" to "my computer" - is your intent to install RAM (if possible) from your computer into the laptop?
