I am currently using ati catalyst 10.12. When I overclock my graphic card from 625/993 to 670/1053, windows crashes about 1 min after I boot into windows. I have opened up my case, the fan is running on the graphic card and it wasn't hot. I also ran hwmonitor and the temp was on 40C. I have used the overclocked settings on older version of catalyst and there was no problem playing games for hours. Temp max was 60C using catalyst 10.11. Anyone having this issue with 10.12?
