MT/s = MHz? noisebomb44 By noisebomb44 October 6, 2015 in CPUs, Motherboards, and Memory Share https://linustechtips.com/topic/462465-mts-mhz/ More sharing options... Followers 2 Go to solution Solved by Glenwing, October 6, 2015

Yes. Megatransfers is the actual unit for those numbers, not MHz.

 

You'll notice memory is not listed as "2133 MHz", usually it's just "DDR3 2133". That is because it doesn't actually operate at 2133 MHz, it operates at 1066.6 MHz, but because it's DDR it does two operations per cycle, so it's as if it were 2133 MHz, but it technically isn't. So the proper unit to use would be 2133 MT/s which is the actual number of transfer operations that occur rather than the frequency, since those are no longer the same number with DDR memory. So you can think of "MT/s" as basically "effective MHz".

    The highest DDR3 data rate = 2133 MT/s

    The highest DDR3 clock speed  = 2133 MHz

     

    are those the same thing?

    Hz = 1/seconds

    Don't ask to ask, just ask... please 🤨

    They are equivalent. 1 Hz or 1/s can be read as "once per second" or "one <thing> per second." Thus 1 transfer per second (T/s) is 1 Hz, and 1 MT/s is equal to 1 MHz.

    yep. Hz refers to basically anything to measure frequency. MT/s is specifically what memory does, but you can call it Hz as well. T/s is transfers per second (with MT/s being Megatransfers per second)... you can just call it Hz or MHz since you're just referring to frequency and it's easier.

    Thanks! this is gold, none of my sources even tried to mention that
