*Speed (MT/s) - MT/s measures the actual data transfer rate (speed) of DDR (Double Data Rate) SDRAM. MT/s stands for megatransfers (million transfers) per second and represents how much data is transferred during each clock cycle. DDR SDRAM memory modules transfer data on both the rising and falling edge of every clock cycle (1Hz) and is effectively double the Clock Rate (MHz).
