Not long because some cards don't work and therefore watchdog stops the miner. Add "-wd 0" to your command line to ignore failed cards as I told you already:
https://bitcointalk.org/index.php?topic=1433925.msg14837013#msg14837013Then when you confirm that it works, use "-di" option to select working cards and you can use non-working cards to mine something else if you cannot make all cards work.
Have you tried it? It seems no, instead you created several threads to discuss your problem.
I love you
Sorry for not following your instructions earlier.
It seems like it is working like that with -wd 0.
As far as I can see GPU #2 does not work.
Do I need to do anything else or can I just run it like this?
EDIT:
GPU #2 just started to mine.
So all 6 GPU's running like that
