clockspeed

Hi. I just ordered the TridentZ RGB DDR4 32GB (16x2) clocked at 2400Mhz. I will be using this with Ryzen 7 2700x and X470 motherboard. Now my question is if I overclock the RAM 3000Mhz will the performance be same as buying 3200Mhz or 3000Mhz RAM? or Should I buy RAM with faster clock speed...
