Don't overclock, maybe your system isn't enough for this clocks. Or even the card. Overclocking when your system, voltage or card is not good enough for the clock may break the card and void warranty. So I don't recommend that. If you however sure your system or card is OK, have you tried giving lower clocks like 500Mhz?
