Do you have any problems with GPU mining, post it here. We will try to solve them.
I had this one
Gpu usage on 2 of my GPUS 7950 increasing and decreasing. Other 4 worked fine with continuos 100% usage. Same computer configuration on all cards.
I used same clock and tryed even to use stock clock but it didnt worked. I just started to use CG miner instead of GUIminer. I am not say tht GUI is not good but that solved my problems.
