I don't want to quote because the post he made was very long.  It's been awhile and I got help from the guys on here and the ones in the Kano Discord, but adjusting the vCore voltages for whatever reason made everything happy.  I currently have 9 Compac F's running at 500MHz (I am waiting on another batch of Gekko hubs so I have one on a hub that can't do more than 2.0A (if it blips above for more than a second it shuts the port down and resets the stick), but I have all 3 hubs connected via their own USB cable to a single Raspberry PI 4 (8gb version). 
Rasp Pi4 has only 4 usb ports, how do you manage to plug them all in including keyboard & mouse

and i assume you're not running windows, as i tested out 500MHz on windows, the WU sits at 4,4xx/m while yours runs @ 4,6xx/m.
  is it on Linux ?

The vcore voltage adjuster is the little VERY small phillips head looking screw on the bottom right of the PCB if you are looking at the heatsink side.  There is a post somewhere in here talking about adjusting them and how much to.  I went through and did every one of them one at a time.  End result though was all 8 (now 9) working together with no issue

     I will search for the post, thanks.
Also i noticed the V - adjuster has 2 flat ends, while adjusting each of them, did they all end up in the same position ?
If so, what is the position ?
