Sorry.  New to this FOSS stuff.  OE is a complete OS download with local code
not pulling from mainline kernels (from what I can tell).  It was tricky for me
to patch it.  I am trying to be transparent so others can reproduce my results
easily.

OK- I built many.  368 is the closest I got.  I have to head to the office.  I
uploaded all dmesg, tests.  What I don't understand is the pll numbers go up
and down, despite having the higher max vals.  This concerns me..

Hope it helps.  I assume you do not want to run all pc's at max.  Else
tolerances at the hardware/silica/chipset level may result in similar results
to my sys.  But at least now I can tune my sys.  :)  

368 is much higher than 100.  LMK if you need more. TIA.
