Hey guys i just updated my old amd catalyst into the 15.12 version. The problem here is that i can't overclock my gpu at all with this update. the moment I touch my memory clock my gpu temperature immediately rise to 40 degree and won't go back down even when i do nothing at all. It also lock my memory clock and i can't go back to the default memory clock setting. For example the default memory clock speed was 1400 if i go up to 1445 and hit apply and immediately hit the reset button it won't go back to 1400 and it is stuck at 1445 and wont go lower.
