Okay,
I found out I needed specific drivers from Samsung for the M.2 drive. Got those and the Magician SSD optimization app as well. Seems to be working great.
Used the clean instal tool from AMD and reinstalled the graphics driver.
There IS a newer BIOS release available from MSI, but not sure if that is necessary.
I put it into what I think is the lowest Overclocking mode ( they make it so simple now) and enabled XMP mode. Big difference in overall system performance, yet when using Raptor Pro on certain patches, if I play an arpeggio slowly, then increase the speed of the notes, the audio begins to break up horribly as the sustain of the notes begin to overlap.
Been playing with the disc buffer settings, both lower and higher, but I still get breakup. The CPU Meter stays low (I have Load Balancing enabled) but one bar will jump high and the sound distorts. I seem to hear slight distortion even when no cpu bars go high.
To be clear, the playback and recording of Sonar seems to be working good, it's the soft synth plugin, real time sound synthesis part that's totally uncool. Ya know?
