First, you should go to your laptop's manufacturer (official website) page and view the specific specs on your device. Most will list the current RAM specs and speeds as well as have a list of approved RAM (Brand and model) for your device.
You may use this command on cmd prompt - systeminfo or sysdm.cpl or SystemPropertiesRemote

And the second option is, you may use a third-party app/website that will scan your computer and return to you the value of your internal hardware and from there you'll be able to match RAM with your existing device. A few will also tell you the maximum amount of RAM that can be used in your laptop. This is to say, your laptop can only support 4GB and you install 6GB, in the end, only 4GB will actually be usable, the remaining 2 will literally be wasted.
