    What about Trinity / Piledriver with GCC using -bdver1 -bdver2 ? Will they have any positive effect?

    I guess all of them were default and configured by SPD on chip/bar?
    At a guess, the timings don't work out ideally with other clocks in the data path? If there is a 2:3 (or 5:4) ratio in there somewhere, it could make the performance a bit more weirdly sensitive to instruction timings and such.

    The highest RAM frequency officially supported is 1866MHz so it's not surprising that was sent to review sites. What's surprising is that 2133MHz is not officially supported, even though it works.
