First of all i know how to overclock i just can't get it to run stable, im don't mean artifacts either. The card literaly over hits in a split second. As soon is a start a game at anything above the factory setting it overheats. My case gets great airflow its an antec 900 with and an additional side fan pulling hot air from the card out of the case. I need to know is there anyway to get around this. Ohh and my fan on the card is running at 55%.
