A thermal envelope that wasn't even close to being approached. I was a solid 40 degrees below the max of this card.

As long as restart fixes it, there's nothing to worry about.

Yeah, wasn't too worried. Just wasn't sure what was exactly causing it. Thanks smile.gif

Nvidia actually released a statement asking users not to run furmark as it can damage a card. Just something to consider while testing your OC: http://forums.nvidia.com/index.php?showtopic=194254

65 degrees on water?
Seems quite hot that,mines never been over 52-53 degrees in summer @915core.

Do you have high ambients?

It's caused by the driver not fully recovering from the error that was caused ... until you restart thumb.gif

I don't see how it would do any more damage that any other stress testing... with proper cooling and safe volts, there is no reason it would cause issues.


 It can create loads on the GPU that 3D graphics will never induce. This is the reason why its not recommended for OC testing. 

 

**the google link in my post has plenty of stories about people that didnt see any issues stress testing OC's with Furmark either rolleyes.gif ..there are plenty more on this forum too.

Regardless whether furmark should be used or not is here-nor-there...I have seen the same issue pop up in BF3, EVGA OC Scanner, 3D Mark.

Do you have high ambients?

At that time, ambients were around 27C and under full load from BOTH Intel Burn Test and Furmark.

During just Furmark tests at standard ambient temps, I never went higher than 54.

I understand that now, definitely interesting that the driver in a way has safeguards built in.

And in plenty/most of those stories people are complaining about the temps being outrageously high. Like I mentioned earlier, where I chose to use furmark is here nor there, as the same issue happens with other programs.
