So I'm using MSI Afterburner to do my overclocking, and I have a 750w continous power supply. But when I overclock I can only seem to run any game for about 10-15 minutes before it freezes. Metro Last Light will just freeze and BF3 will say "Direct X Error". When I don't Overclock the game plays fine. Here are the values I've recently tried that also didn't work. Core clock +50mHz, power 110%, memory clock 0%. It's not that the card is getting too hot, it seems to stay under 45. Any ideas as to why this is happening? I would really like to get the most out of these cards. Thanks.
Here's my rig
