Assuming the laptop can make use of the 16GB of RAM, it will not improve your gaming performance at all.
You need faster RAM to gain performance, not more RAM. Becnhmarks have shown that using faster RAM does improve gaming performance, but that was tested on a desktop PC with a motherboard capable of faster RAM.
You need to find out what is the fastest RAM your laptop can use. I might be in the manual or you need to call HP.
