Below is the link to the service manual for your notebook.
The memory upgrade info can be found in chapter 1.
12 GB will work, but here is why you don't want add just 4 GB.
When memory is installed in mismatched capacities, it runs in the slower performing single data rate (SDR) mode.
Memory that runs in matched capacities runs in the better performing dual data rate (DDR) mode.
So hold off on upgrading until you can afford another 8 GB module to install.

soo correct me if i'm wrong (cuz i'm new to this) but basically what you're saying is that if i decided to upgrade my ram to 12gb it'll run slower than my current 8gb even though the 4gb and the 8gb are both ddr4 and have the same 2666 MHz fequency (both samsung btw if that makes any difference)?? anywayyy, thank you for all the tips

In your specific situation, because the one memory slot is empty, the PC is already running in SDR mode, since you have an 8 GB memory module in slot 1 and 0 GB of memory in slot 2.
So, if you have a 4 GB memory module lying around and you want to install it, the PC should run better with 12 GB of memory running in SDR mode vice 8 GB of memory running in SDR mode.
If you have to buy the 4 GB memory module, then in my humble opinion, you would be throwing good money after bad, when you can spend a little more, get an 8 GB module, have 16 GB of memory running in DDR mode.
