I have the same issue, I did call ati and they said that they dont worry about gpu temps intell around 110-120c so i wonder if the fan ramps up or not?. Also has anyone got rivatuner to work on auto for fan control as i have only got it to work on fix fan only. P.S. because in my left handed thinking 110-120c is to hot for me
visiontek's bios? where is that? im interested as i have a visiontek 3870x2 as well. I can push the memory OC to 955 (max catalyst allows) but the GPU can only go to 855mhz. It becomes unstable at 860mhz. and my card runs super cool since i have 2 120mm fans blowing air directly at it.
Riva Tuner 2.08 is what I have and the auto fan speed doesn't work correctly; it usually just stays at 34%. I have it set to fixed at 40%. I just finished a 3dmark06 run @860/955 with the fan speed at 40% and my max temp was 80 degrees. I'll try higher core soon, maybe tonight. I think you can use RivaTuner to get the core and memory higher than the CCC will allow, but I heard you lose the powerplay feature.
