Every graphics card has different oc capability. Yes, you can pass the heaven benchmark doesn't mean that your gpu is fully stable. Recommended ways are to run the heaven benchmark and directly play heavy games like BF3 and crysis 2/3 to test for gpu stability. Run the game for at least 2 hours to see for any anomalies or artifacts. If there is none, then your gpu is stable. Since the game crashed, you need to lower the core clock until the game runs properly smooth. If reducing core clock done nothing, please reduce the memory clock. You can try to increase voltage, increase the fan speed manually to like 60%, 85C is quite high, dont over 80 degree celcius is recommended. So lower the core clock!

You know what?....That's great. Hence, dont increase the voltage d...it will increase the heat......is it easy to apply the TIM onto the graphics card die? @@ i never try thou..Mind sharing with me?

What TIM hv u used? Arctic MX4?

Cool. Mind share a pic of ur rig? Haha ur specs seem so tempting!

Good, sometimes when your gpu is stable with the heaven unigine test doesnt mean it is fully stable. Games like BF3, Crysis 3 are still important for us to fully test the gpu stability. Playing those games like 2 hours are enough to test it. Glad to hear that yours is stable at that clock.

Nice Maximus V Formula...Sli somemore...u really rich hahahahha
