Ok, I downloaded and installed the new beta version of ATI Tool 0.0.23 and I overclocked my videocard. The default core speed was 324 and memory speed was 189. I made a new profile and brought the core speed to 375 and memory speed to 195. Now, after I close ATITool and turn it back on, it goes back to my default core and memory speed. I tried so many times but that keeps happening. I even clicked the "Set Clock" thing but it just doesn't work for some reason. There are no artifacts also. What's the problem? Did i miss something? Did I overclock my videocard too much? Is it a bug? Someone please help. Thanks.
