If you cannot see or access the unused slot near the used slot under the RAM door, then unfortunately it is probably on the opposite (top) side of the mainboard in your machine. Jack E/NJ

Hey , can you look at this picture: 
My ram speed is so slow. Changing this one memory can improve performance?

Might make a huge difference but no 100% guarantee. I might be tempted to try  replaceing the 8GB with a 16GB DDR4 module just to see if it makes a huge difference as long as I could return it to the vendor if it doesn't. Just to avoid adding another 8GB module to the top slot.  Jack E/NJ
