    DDR4 speed typo in UltraZed-EV HWUG?

    buckd

      Hi,

       

      In the hardware user guide here:

         http://zedboard.org/sites/default/files/documentations/UG-AES-ZU7EV-SOM-G-V1.pdf

      I read that DDR4 RAM can do 2400 Mbps (mega bits/sec) transfer speed. Is this correct?  Or is it actually DDR4-2400 RAM that that does MT/s (mega transfers/sec), so 2400 * 64 bits (x64 mode) which is actually 153,600 Mbps?

       

      Thanks!

       

      FYI we're attempting fast PL DMA transfers and are searching for bottlenecks. If the spec sheet is right, and not a typo, then it would be our bottleneck.
