So I have a rig which can handle a maximum 64GB DDR4 RAM. I have 8GB installed on the Motherboard right now in the form of 2x 4GB chips. I am looking into getting 16GB more in the form of 2x 8GB chips. I am not sure what the MHz are on the currently installed RAM but I know the chips I am looking to buy are 3200 MHz. If my old chips and my new chips have different MHz capacities would anything bad happen if all are installed on the mother board?
