    Ryzen memory clock misreport

    in Memory Heaven (air/extreme)

    Posted

    it's been awhile, there are records out there since ryzen 3000 launch 

    I think it's not hard to figure out there are mis readings of ryzen 3000's memory speed up to 5.1GHz

    which barely there is no single one software can particularly report it right

    people choose not to say or take advantage from it, used for marketing or competition, some may presented for companies

    last week I take a chance to check out those weird results, and double check with some softwares

    and oscilloscope, and found out those softwares are truly broken and fail to report the right frequencies

    as you can see from attached pitcures, all software except ryzen master are reporting the wrong clock

    and they still can pass cpuz validation which means software fail to report correctly

    though, rzyen master is not always right, becasue it can't detect the out side BCLK, once you jump up 

    the BCLK rzyen master only reads the memory clock at 100MHz

    here is the validation I just add to show CPUz's buggy memory frequency

    CPUz shows 5.916GHz, but actually it's 55*102 not 58*102
