Windows 7, changed many GFX drivers. I have 3 7970 card and using the riser with power supply on it . Why is my 3rd card only hash about 360KHS while other cards hash 700Khs. If I switch the card order its always the 3rd card, so hardware does not have problem.

It is a common myth that Bitcoin is ruled by a majority of miners. This is not true. Bitcoin miners "vote" on the ordering of transactions, but that's all they do. They can't vote to change the network rules.

Its your settings, try playing around with your GPU-thread 1 and 2 and the threads count... leave voltage, engine and memory clock alone until you get the best threads...
