hi! I currently have 4x4gb ddr4 2400 for a total of 16gb installed on the 4 out of 8 DIMM slots of my mobo (msi x99s sli plus).

Im planning on adding more RAM (I use the pc for cad and intensive 3d model and rendering), my question is:

can I add 4x8gb to the remaining 4 slots to have a total of 48gb or it should be the same 4x4gb sticks?
