Trying out a few hubs from Amazon here. I only have 2 sticks so far.

First this Orico: https://www.amazon.com/gp/product/B071FNC3VY/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1
Was only able to run both at 600mhz, any higher and at least one would stop hashing after a few minutes.

Next the Pluggable: https://www.amazon.com/gp/product/B00RM5OF70/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
While using this one I initially ran one stick at a time while upping voltage until they were nearly error free at 900mhz. Then I tried both at 900mhz. Every time one would stop hashing after a couple of minutes.

Finally this Anker: https://www.amazon.com/gp/product/B00VDVCQ84/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1
Rock solid with both running at 900mhz. I wish I had more of my stick orders in to see how it does with more sticks on it, but I will soon enough.
