Hi

How it's possible to make script that copies my own cgminer.sh script to /etc/init.d/cgminer.sh on startup?

And how to make script that restarts the miner with like 3 hour intervals? As there has been some downtime with overclocking and unit just shutting down=)

now 500gh/s semi-stable 2 module november saturn, was on during the night. Started clocking each die individually. To make it stable i needed to get rid of those fault 4:s turning up after some time. I think they have timer on them and that causes some overtemp-protection to trigger in after some time.

Values for asic 4 are 361 and asic 0 varies in between 361 and 2C1.

vrm's for asic 0 die 3 make fault 4 risen above that 30.  Asic 0 is heating more than 4 in overall.
