Hello all,
I am new to mining. I just built a mining rig with an ASRock 970 extreme 4 mobo and a Sapphire HD7950 4L GPU. I'm trying to use BFGminer, however my computer just completely turns off randomly when mining. What are the best arguments / flags to tweak in bfgminer? The best I can get is no greater than 300 MH rate, which I know this card and do 450... The current flags I have been using is below. I am running the latest catalyst AMD kernel for the vid card, as well as the latest SDK. I compiled bfgminer from source, and am running Ubuntu 13.04 Raring.
./bfgminer -o

Please let me know your thoughts. I am just experimenting with bitcoin and am finding it fascinating!
