i can't get my third compac f miner to run for any length of time at the same mhz as the other two 
wanted to set all 3 miners to 575mhz now - the first two went step by step to 575 with no problems and the third stopped at 405mhz and then went back to 200mhz... now he tries again to go to 575mhz
what could be the cause of the whole problem?
my compac f including fan are connected to the gekko usb hub as follows:

my compac f including fan are connected to the gekko usb hub as follows:
Code:
0: GSF: port 7 (compac f) <-> port 6 (fan)
1: GSF: port 5 (compac f) <-> port 2 (fan)
2: GSF: port 4 (compac f) <-> port 3 (fan)
1: GSF: port 5 (compac f) <-> port 2 (fan)
2: GSF: port 4 (compac f) <-> port 3 (fan)
You maybe pulling too much power from the USB port and the regulator is shutting it down, have you been tuning that setting with the USB Power meter? I can't stress that enough even though someone said you can eyeball it, it's probably true when you are at 500-525MHz but at 575 you are starting to pull some extra power and if you aren't sure it is just going to keep failing.
I am running 12 sticks all at 575MHz, as you can see in my previous pictures only 5 or 6 have Noctua fans, the rest are only cooled by a Noctua fan on top of them blowing down. Since I have 2x USB Power readers I literally spent quite awhile tuning them doing only 2 at a time where they MAX at 3.1A (some were not happy if I tried to keep at 2.9-3.0A). Each stick is different so what works on one, 99% of the time won't work on the other. I learned this long ago when I only had 3-4 sticks and started messing with the pot. on them. LOL!
