you can't go higher than the speed of the RAM that is currently installed, whatever the system bus speed is for the laptop is the max speed of ram you can use. If you put in higher speed ram is would be accepted but run at the slower speed. like a Ferrari can't show its potential in 30 mph zone.
all you can do is remove the 4GB ram stick and replace it with an 8 GB to give you the total RAM of 16GB.
thanks and take care. Jay
