hmm my eth-proxy is ok, my .bat worked in the past and I have modified nothing and my sapphire nitro r9 390 (that I bought just to offset the price, eth can of course tank without warning).
at nanopool with ethminer. the card spool up under load normally.
so lemme tell you a story. it stopped mining (DAG has read/write permission, the are 3 now DAGs in the default ethminer folder. and it spooled down for many hours at many different times in the past several days. so i know it stopped mining. internet is fine.. should I be worried?
its spooled up now and working..normal is 1040mhz clock 1500 mem (that is default setting for nitro) @ 31 gh/s
Hmm I have two boxes running 24/7 many weeks without hiccups (only 1 gpu per machine). Have you checked that the psu is OK? Temperatures are within normal operational range?
I used to have a rig with old busted up crap (3x old 290s) mining away and it restarted 1-x times every day. I never found the cause before it completely died, but I think it may have been the gpus where faulty, crashing the drivers and bringing the rig down. In the end I think all equipment died, all except cpu and ram, but everything else stopped working.
Every time the machine crashed it needed to create new DAG files. But mostly I had to delete the old ones prior to starting the rig, otherwise it was mining 0 MH/s at full blast.
