Meaning that the transfer rate is roughly twice the speed of the I/O bus clock. When it comes to measuring DDR RAM speed, MT/s and MHz are used interchangeably, which is not actually correct.ĭDR stands for double data rate which means data is transfers on both the rising and falling edges of the clock signal.
Why is the speed of this RAM kit shown as 1066 MT/s instead of 1066 Mhz? On MacOS however, this number is rounded up so that it shows 1067. Good question! The actual speed is 1066.66 MT/s but in the RAM industry manufacturers round this figure down to 1066. Just contact us if you need help! Why is this RAM kit 1066 MT/s when my existing RAM is 1067 MHz? Here at RamCity we've been upgrading Mac's since 2004 and have experts ready to answer your questions.
