    I Solved AMD's 4 DIMM PROBLEM

      Hi All

       

      Am not sure if am sharing this information in the right place but here goes

       

      what I found to be the main problem with running high speed memory on ryzen when running 4 dimms was the ohm rate it was set to and recommended to be set to this tip will also help with 2 dimms and high speeds

       

      first thing to do is set your xmp profile in my case I have ddr4 with
      base clock of 2133 15-15-15-15-36
      and oc profile of 2933 15-17-17-17-35

       

      after setting your xmp reboot back to bios

       

      if your bios still shows the base clock then you have the same problem as me (base clock speed on the right of bios still shows 2133)

       

      so I fixed this by reducing the ohm rate from 60 to 40

       

      now I have 4 dims running at 2933 with no issues or problems

       

      so with a further overclock of the FSB to 102.2 they are running fine and stable at 2997

       

      not sure if this is the right place for this post as its my first post here and not quite sure where to post this but I hope this helps anyone having any memory problems

      ill be back to post more about this as I have been advised I can run the fsb at 104 with no issues so am running some tests and all seems great so far

      thanks for the advice
