You should check out the temp of the card before trying to overclock. Run it on normal settings with a demanding game for about 15 minutes, close it out, and immediately check the temperature of the card.



If you really want to do overclocking, do some research, learn about how it works before attempting yourself, so you lessen the chance of frying your card. Also might want to check out ntune.
