I need to play with it some more.  But the hub is really pretty good.

 I am able to run quite a bit higher freq 350 and 0 errors  2 sticks around 20gh.

Yet I can't run 3 sticks at good numbers..

I have many hubs and will do more testing tommorrow.

I have 3 pc's
 I have 1 doing windows 7 pretty new build and i5 cpu ------------ This is doing 8 sticks at freq 150
 I have 1 doing windows 7 in a vm shell a mac mini i5 ------------- This is doing 7 sticks at freq 125

 I have 1 doing windows 10 an i5 cpu new build new mobo -------- This is doing 2 sticks at freq 250 perfectly  I can go to freq 350 perfectly on 2 sticks  So far this setup is the really weird one as it allows 2 sticks as high as freq 350 yet does not  like to do 3 or more sticks.
could be a mobo issue. 

I am a bit tired will get back with more info
