"Edit - I looked up the specs of the CPU and it only has a single memory channel, so adding a module with higher than 4GB capacity won't matter since you can't run dual channel mode. Get an 8 or 16GB 2133Mhz module if you really need more than 8GB. "

And here is the exact information you are looking for.

Memory controller

The number of controllers: 1 Memory channels: 1 <---------- Single Channel Supported memory: DDR4-2133 Maximum memory bandwidth (GB/s): 17.1

That's your CPU. It does not have Dual Channel support.
