DDR4 3200 refers to DDR4 memory with a data rate of 3200 megatransfers per second (MT/s). Its actual clock speed is 1600 MHz, but because DDR (Double Data Rate) transfers data on both the rising and falling edges of the clock signal, its effective speed is 3200 MT/s. So, DDR4 3200 runs at 1600 MHz actual clock speed, but is marketed as 3200 MHz effective speed.
