The battle is over. Microsoft is finally changing the measuring methodology in its Task Manager from Mega Hertz (MHz) to Mega Transfers per second (MT/s). This comes amid the industry push for more technical correctness in RAM measuring, where the MHz nomenclature does not technically represent the speed at which the memory is actually running. While DRAM manufacturers list both MHz and MT/s, the advertised MHz number is much higher than the effective speed at which the DRAM is running, resulting in confusion and arguments in the industry about choosing the correct labeling of DRAM. A little history lesson teaches us that when single data rate (SDR) RAM was introduced, 100 MHz memory would perform 100 MT/s. However, when double data rate (DDR) memory appeared, it would allow for two memory transfers per clock cycle.
