Why is the speed of this RAM module shown as 1600 MT/s instead of 1600 Mhz?
When it comes to measuring DDR RAM speed, MT/s and MHz are used interchangeably, which is not actually correct.
DDR stands for double data rate which means data is transfers on both the rising and falling edges of the clock signal. Meaning that the transfer rate is roughly twice the speed of the I/O bus clock. This RAM module runs at 800MHz per second, but the effective rate is 1600 megatransfers per second (MT/s) because there are 800 million rising edges per second and 800 million falling edges per second of a clock signal running at 800 MHz.
