None of my units run properly. I've tried everything, but the cards just drop offline if they show up in the first place. Then slots start going dead entirely and cards never show up on them again. I thought maybe I had a bad component. I just got two new 100gh units today, that I bought specifically to get my October unit working finally. These ones are just doing the same thing, so there goes that plan. They don't even run for 2 minutes without dropping cards. I've lost so much time and money and these things it's disgusting. I've averaged about 50gh on my october unit, and I'm talking about 15 cards not 1.
Try this post from GandalfG from a while back that was helpful to create a bunch of troubleshooting configs.
I recently had a rig go "weird" on me where a card decided to just up-and-die after 2-5 minutes. Plenty of airflow and cooling. It's in a Spotswood case for stability, and had been working fine for a month or so now.
Had to set the one "weird" board to aIfDSo 52 in /opt/bitfury/best.cnf and the rig has been humming along well since.
pi@bf02:/run/shm$ cat /opt/bitfury/best.cnf
1 aIfDSo 52
2 aIfDSo 52
3 aIfDSo 52
4 aIfDSo 52
5 aIfDSo 52
6 aIfDSo 52
7 aIfDSo 52
8 aIfDSo 52
9 aIfDSo 52
10 aIfDSo 52
11 aIfDSo 52
12 aIfDSo 52
13 aIfDSo 52
14 aIfDSo 52
15 aIfDSo 52
16 aIfDSo 52

Okay I got it working. The only problem I got now is that I can only get bank number 1-11 working. I have 12 plugged in. but only 11 looks to be working.
I’m have a problem running the rig when I have all 16 h boards plugged in. it would just power up and shut off. But when I remove 4 (left with 12) it would power on and I would be able to hash. However it would only hash with 11 boards. i've also notice that after hashing for about 20min or so, some of the h boards stop hashing. only 4 would be hashing still and the rest would stop. why is that?
Any idea on how to fix this problem.
i doubt that its the psu. but i could be wrong. my psu is 700w and 570w towards 12v. i have 2 pci-e cables on the psu.
if you think its the psu. please direct me to the right place to buy the right psu.
psu model:
coolmax
cu700b
Mboard version ?
mboard is v3.0
Ok there is 16 factory overclocked board. I think PSU can't handle that much.
First set speed on all boards to 52
Login to Pi and do command
rm /opt/bitfury/best.cnf ; for i in {1..256} ; do echo -e "$i\taIfDSo\t52" >> /opt/bitfury/best.cnf ; done1 - After that try run with 12 boards for test for 30 min.
2 - If no hash drop, shutdown miner and add 1 more board.
3 - Make test.
Repeat for max board count working stable.
I strongly suggest decrease voltage on all boards. Turn little pot near Pulse inductor on Hboards counterclockwise about a quarter turn or so.
