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.
Try increasing your power factor to 20%..
this screenshot is not exacly mine, i found it on internet. But mine gpu usage was like this. I solved the problem
What was the problem then? I also have this when I setup my GPU for the first time, I tried increasing power factor and it work. Did it work for you too?
nope didnt woked for me, i tried everything, this can happen when temp is high but mine wasnt high. I just unistaled GUIminer and instaled a CG miner. And now it wokrs perfectly
