I'm using the same settings on stratum and front end like suprnova , did the cgminer crashes just when you mine on my pool ? or is happening on other pools to ?
cgminer crashesh due to the aspiration of people to increase intensity
On undervolted 280x and not overclocked, -I 4 and -w 64(default for kernel hefty) all is stable 1050 gpu 1500 mem, 9.6Mh
Increasing of intensity or increasing of work size does not lead to better results
