First to my previous problem I think I have worked it out to a power issue. I can get 3 Newpaks to run at 400MHZ on a GekkoScirence hub with 8 Amp power supply. If I try a fourth one then it eventually kicks one or more of off. So my question is have I got it wrong? I don't have the meter to confirm this unfortunately. But I want to think that I am wrong because why build a hub with the ability to run 7 sticks if you cant feed it enough power to do so?
After much trial and error this is what I ended up with to get stable. I have 1 stick in a usb on the PC directly and 4 on the hub. ! of the ones on the hub shut itself off. Lots of reading on the previous posts to even get to here.

Second what is the minimum system needed to run a farm. I have a MSI H270-A Pro motherboard that I was going to build out for GPU mining. Could I instead build it out with Linux and run a far of sticks on it? Lots of USB ports on this thing. Limiting factors? RAM needed? Run from Thumb drive -vs- SSD?
Could I run say 6 R606 one to a USB port? or can you put multiple R606 on a hub without hitting a USB bottleneck?
Sorry lots of questions. Tweaking these things is a bit addictive.
