I see this used in a lot of setups. I'm using dual 7970s, should I add -k diablo? What does it do? ^_^;;
SECOND QUESTION:
I use --gpu-engine 1155. It is not dynamic. When I try to use a static memclock --gpu-memclock 350, it doesn't work, and sets it to 1375. Why does it do this? ;-;
1) Did you read the readme for CGMiner? The "-k" option specifies a kernel. Diablo makes a kernel (also used in his own DiabloMiner), and is somewhat popular for 7xxx cards. I have found that letting CGMiner determine the best settings for 7xxx cards yields the best results, tho, so I would remove this comment.
2) CGMiner can only clock the memory 150MHz lower than your core engine clock. For you, at "--gpu-engine1155", this would be "--gpu-memclock 1005". If you set anything lower than this, it defaults to the cards stock memory speeds, which is apparently 1375 for you. I would recommend not using the "--gpu-memclock", and using the "--gpu-memdiff -150". Either one would work, esp if your clock is not adjustable, or completely static.
