Hi, im a total noob when it comes to overclocking, have used ati burner and right now using evga, changed gpu clockset to 135mhz and the memclock to 295, if i go over 300 the game runs fine on about 70 degrees, the problem is that both evga and ati afterburner shuts down ( i dont have both installed or running at the same time) if i go over 300, anyone else have this problem?
