ETC+SIACOIN dual miner is giving more than LBC coin with AMD VGAs, even with woolf "special" miner, who I don't recompensed at all. After 6 month of mining, and just one week using woolf miner and LBC with R9 380 VGAs, my friend/partner lost three rigs, to be precise thee PSUs CM M750 burnout/dead.

LBC is nvidia's territory..specially now at low prices and higher network hashrate.
should have bought w0lf's miner early, dump mined LBC for ROI of the purchase.
your PSU is the culprit. don't cheap out on that.
I have better in development.
