Why is the speed of this RAM kit shown as 800 MT/s instead of 800 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 kit runs at 400MHz per second, but the effective rate is 800 megatransfers per second (MT/s) because there are 400 million rising edges per second and 400 million falling edges per second of a clock signal running at 400 MHz.
