Go up one level in this thread



these are two examples of slates upgrade from 2x1400mhz,  to 2x1533mhz.


out of the three tests, one of the tests had the analysis shown at different
  times and different depths, didnt seem to be a good comparison.

but the two tests below are close enough to see a difference, since the
time and depth were pretty close in the analysis.

i added the kns. value.     first test gain of 137kns.
     second test gain of 171kns.  first test was accessing egtbs
