Apparently you are mining from a country with low electricity. These cards at 250 watt consumption without BIOS modification and the almost 20 Mhash they give in a country like mine where electricity cost is 0.16 euro/kwatt surely its a suicide to mine with these cards. In fact if you check Ebay Italy you will find these cards being sold as cheap as 80-90 Euro so for some people who live in India or Iran where electricity is super cheap these maybe a really good option to mine but for Eurozone main countries no. I am happy at 90 watt and 24.1 Mhash mining ETC with GTX 1060 3GB.
