thanks you, somehow i manage to get it running by using "-d 0 --gpu-platform 1"
However, i dont see the GPU temp and fan speed in cgminer, it was blank. Also i tried "--gpu-fan 50 --gpu-engine 1060 --gpu-memclock 1500" (which was my optimal setting for mining) but there is no change in hash. So i think those command dont work. Afterburner and trix cant too.
