Integrated GPUs can use some RAM for video exclusively.
This can also be controlled / adjusted in some BIOSes.
What graphics card do you have?

It is generally recommended to use identical RAM sticks by the same manufacturer.
your CPU 3550H use share memory for video ,
this memory video part cant be use for classic memory usage , it is reserved for video ONLY
