Today i went ahead and played with small overclock. Everything went well for a while then bam system reboot due to graphic card error. Now every game i run will crash with driver saying it had to close app cause of card error. The card is still in warranty and it works fine in 2d like destop but not for any benchmarks or games. I sent in a rma for it. I have a back up 5850 to use till it comes back. Anyone got any idea's why its doing this? I didn't adjust any voltages.
