I was seeming to get good hashrates relatively (like ~520 - 550 GH/s) Just got home see that my rate was around 385 with two dead cards (currently I have my miner restarting once an hour in case that happens...look like it didnt seem to help this last go round
)
to restart my miner, in ssh type
crontab -e
*/60 * * * * sudoopt/bitfury/start-miner.sh
No offense, but this kit is wierd, awkward, lacking, whatever you want to call it. So far I've spent a lot of time:
Taking all cards out and slowly adding them and running it for 30 minutes to see how high they go and to attempt to set them to around 30 GH. I tuned the majority of them to stay on, here is my up to the minutes stats from CAT:

Not terrible but by no means any good by what Dave quoted earlier. (might have increased slightly because my main window shows 475 GH/s)
Good job to the
dumbass misguided helper who chose the smaller than atomic particle Potentiometers (something just a little bit bigger that wouldve been easier to catch with a screwdriver would have made all the difference to me) that are too small for anything. Smallest screwdriver I could find in frys barely seems to catch them most of the time. Extremely frustrating when trying to undervolt the cards for the sake of keeping them on.
I have a SHIT-TON of heat sinks - The only thing I could think to do more now is to buy up another 32 tiny heat sinks to put onto the top and the back of the voltage regulator.
