HI monsanto!!
i don't try to reduce the intensity of mining.... yet.
It's not a concrete GPU that hangs ... or a concrete PCIe slot ...or with one riser.... only occurs when I put 6 gpu on a rig.
With 5 slots used, no problem.
Maybe I can edit reboot.bash to restart "./ethdcrminer64" instead of reboot whole rig "r" , but I think this is risky because maybe a reboot is good and only restarts claymore....
Now I'm using nicehash pool ... don't send mails, I think you're talking about ehermine (¿?)
Thnaks!
