Yes overclocking ram puts stress on the IMC in your cpu reducing the amount you can overclock the cpu. However 1600 is not a high overclock and will not adversely affect cpu OC potential. Assuming your on the standard consumer platform cpu's only support dual channel memory so anywhere from 2-4 sticks is fine and with achieve the best performance.
