Yes your motherboard supports that RAM.
But you should not mix different RAM modules.
It is recommended that modules with identical specifications from a kit are used when running in multi-channel mode.

Even though they might look "exact same" modules, there is no guarantee that they will work together. The RAM that goes into a kit (package) has been tested to work together. There are times that different modules, even if they look similar, they could have different IC chips brands.
Manufacturers don’t guarantee mixing or adding one module to another, even when they are the "exact same" model.
